Introduction
This article provides additional data on distribution and ecology of
lignicolous macrofungi in the Danubian Lowland (Podunajská nížina
Lowland). It is a continuation of our previous report (Tejklová & Zíbarová
2018) and summarises records in 2018–2020. We visited again several
interesting localities in the phytogeographic district Danubian Lowland,
mostly in Bratislava City (Slovakia) and its vicinity. According to our

6 Catathelasma 21 December 2020 December 2020 Catathelasma 21 7
taxonomic interests and due to miming of our visits we focused mostly
on lignicolous fungi. This group of fungi is often overlooked by many
eld mycologists, despite its immense ecological importance. For
characterisation of the study area and historical literature on lignicolous
fungi see Tejklová & Zíbarová (2018).
The aim of present work is to provide additional data on distribution and
ecology of lignicolous macrofungi in Danubian Lowland.
Materials and Methods
We focused on macrofungi, mostly on pyrenomycetes, polypores,
heterobasidiomycetes and corticioid fungi, less attention was paid to
agarics (localities were visited outside of the main agaricomycete fruiting
season) and discomycetes.
The article is focused on fungi on the wood and similar substrate (such
as bark) – apart from the true wood-degrading (lignicolous) fungi, also
resupinate mycorrhizal fungi (mostly Tomentella and allied genera)
are included, as collection protocols for those are similar and it is often
impossible distinguish between both ecological groups in the eld. In
addition, we included species associated with lignicolous fungi. Many of
the species recorded from old fruitbodies are not apparently restricted to
this substrate (e.g. some records of Athelia, Sistotrema or Trechispora). In
addition, in some species (e.g. Tremella spp.) the parasitic or saprotrophic
ecology is not evident and they are often included in inventories of
lignicolous fungi. The rest of fungicolous species are included for the
sake of completeness. As borderline between lignicolous and terrestrial
saprotrophic fungi is often blurred, it should be claried, that we did not
include most species growing from ne wood debris on the ground (e.g.
some Psathyrella species).
Data were collected during the eld trips in following periods: 13–17th
April 2018, 5–9th November 2018, 1st March 2019, 3–7th May 2019,
4–9th November 2019 and 4th March 2020 (Table 1). Selected collections
were documented by photographs and/or herbarium specimens. The
macroscopic descriptions are based on fresh material, studied specimens
of basidiomycetes and pyrenomycetes were dried in a portable dryer within
12 hours after collection. Discomycetes were studied microscopically in
living specimens (see Baral 1992). Micromorphological characters of
the rest were studied mostly in the dry material. Microscopic characters
were observed in water, Melzer’s solution and in 10% KOH aqueous
solution as appropriate. Measurements were based on Melzer’s solution
preparations under oil immersion at 1000× magnication. Voucher
herbarium specimens are deposited in the herbarium of the Museum of
Eastern Bohemia (HR) and the Slovak National Museum in Bratislava
(BRA). For other herbarium acronyms see Thiers (on-line). For some
records no herbarium material was collected or preserved, those are
indicated in the text by „not.“ abbreviation.
Nomenclature follows recent general monographs on broadly dened
groups: corticioid (Bernicchia & Gorjón 2010), polypores (Rivoire 2020)
and agaricoid (lamellate) species (Knudsen & Vesterholt 2012). For the
rest of the species groups authors tried to apply a conservative approach
to the generic names.
The full list of studied taxa recorded during our eld trips are given
together with data on circumstances of each record: date, locality, habitat,
substrate and collectors. The records with the same combination of
species, substrate and locality as in previous article are not included. For
each species a presence in the Checklist of non-vascular and vascular
plants of Slovakia (Lizoň & Bacigálová 1998) as well as threat category in
the Red list of fungi of Slovakia (Lizoň 2001) is indicated. As the studied
area is close to Slovak border, we also added the data about species
presence and threat category in the surrounding countries based on:
The Fungi of Austria: Checklist and Red list (Dämon & Krisai-Greilhuber
2017), Red list of fungi (macromycetes) of the Czech Republic (Holec
& Beran 2006), Hungarian list of protected species (Siller et al. 2006)
and presence in Red data book of threatened plants and fungi of the
oodplain forests of the Dolní Morava Biosphere Reserve (Řepka et al.
2017, further referred as Red book of Dolní Morava). It should be noted
that quality and actuality of information as well as systematic coverage
varies among respective checklists of each country. A legal protection
status of species in each above mentioned countries (where applicable)
is indicated. Protected, endangered, rare or otherwise interesting species
are briey commented.

Localities
Most important visited localities (in alphabetical order). The characteristics
of localities are based on The national list of specially protected nature
areas of the Slovak Republic (http://uzemia.enviroportal.sk/). Geographic
coordinates (WGS-84) are given to the centre of localities.
Bodíky

17°26‘51“E.
An area southwest and southeast of Bodíky village. The area is not
protected apart from being a part of PLA Dunajské luhy and much of its
oodplain forests in the area were replaced by plantations of fast-growing
poplar hybrids. We visited some of the remaining willow-poplar oodplain
forests there. Fungal data from the locality are insufcient, we only found
a record of Fimaria leporum by Janitor (1996).

This blue-green coloured tomentelloid species was previously published
from Podunajská nížina Lowland (Kopáčsky ostrov NR) by Čížek et al.
(2007) as the rst collection from Slovakia. Our record (the second one for
the country) is just about 6 km from the rst one, but from rather different
habitat. While Čížek et al. (2007) collected it in a periodically ooded
depression in open steppe habitat, we found it in a closed Populus alba
dominated oodplain forest. For further discussion and description also
see Zíbarová & Tejklová (2019).

In our previous paper (Tejklová & Zíbarová 2018), we reported this
stromatic pyrenomycete from Panónsky háj only. However, our new
records suggest it might not be rare in Podunajská nížina Lowland. So
far, we found it exclusively on dead still standing or recently fallen thin
(up to 5 cm diameter) individuals of Ulmus (directly on trunks or branches
attached to them). We suppose that further searching in localities with
similar substrate and hosts composition could reveal more localities of this
species in warm parts of Slovakia. We believe it is opportunist pathogen
on elms dying from other causes than primary cause of their death.

A stromatic pyrenomycete restricted to Prunus padus in Central Europe
(Læssøe et al. 1999, Vasilyeva & Scheuer 1996, Zíbarová & Kout
2017). While it is rather common in many of the localities we visited
in Podunajská nížina Lowland, it was not previously published from
Slovakia. Nevertheless, there are already unpublished specimens from
two localities in Podunajská nížina Lowland deposited in BRA (Petržalka-
Zrkadlový háj, Dunajské ostrovy NR) and several localities are known from
neighbouring areas in Austria (Læssøe et al. 1999, Vasilyeva & Scheuer
1996). In our experience, it is a part of typical inventory of oodplain
forest of warmer parts of central Europe and it occurs in habitats where
its host is present in greater abundance. However, it is more scattered in
colder parts of the region even if Prunus padus is present.

A corticioid species with conspicuous rust-coloured anamorph, that
could cover several dm2. Most of the records in central Europe are from
oodplain forests (Langer 1994, Pouzar & Jechová 1967), but it is rare
everywhere. Its distribution in Slovakia is concentrated almost exclusively
to Podunajská nížina Lowland (Hagara 2001a).

Like preceding species, B. simile forms extensive rusty anamorph and
it is rarely found in teleomorph stage. We found only its anamorph
(asexual stage) historically named Haplotrichum simile (Berk.) Hol.-Jech
(in contrast to similar B. robustius above). In Slovakia, only one record of
this species has been published (Hagara 2001a), also from Podunajská
nížina Lowland (Rusovce), but there are further two unpublished
specimens from Šúr NNR in PRM (13.X.1979, leg. Z. Pouzar, PRM
845123; 15.X.1979, leg. Z. Pouzar, PRM 845082). It has similar ecology
to B. robustius – it is thermophilous species preferring oodplain forests
in central Europe (Hagara 2014, Pouzar & Holubová-Jechová 1969). The
species is also included in Red book of Dolní Morava (EN, Řepka et al.
2017).

A pyrenomycete with stromata partially immersed in wood that is typically
stained yellow around stromata. It was published for the rst time from
Slovakia by Pouzar (1986) from Šúr NNR, and it remained the only known
locality in the country for several decades. We have not recollected it in Šúr
despite deliberate searching, but to our surprise we found a new locality
in Dunajské ostrovy NR. In the Czech Republic, the species was also
known only from a single locality for a long time, but number of localities
had grown signicantly in past decade (J. Běťák pers. comm., L. Zíbarová
unpublished data). Therefore, we assume the species can be overlooked
and more common in Slovakia as well. In contrast to wet localities in
Slovakia, our records of C. lutea in the Czech Republic are mostly from
markedly xeric habitats (thermophilous oak or oak-hornbeam forests).

concept of the species by Pieri & Rivoire (1997). However, C. alachuana
was originally described from North America (Murill 1938) and descriptions
of American material (e.g. Lowe 1966, Kotlaba et al. 1984) were
in conict with our specimen both in macroscopical (Kotlaba et al. 1984:
“If compared with other species of Ceriporia Donk, this species is a robust
fungus and has fairly long tubes.”) and microscopical (narrower subicular
hyphae) aspects. Hence, we sent the specimen for sequencing and the
obtained ITS sequence was matching the sequence of type of recently
described C. pierii (J. Vlasák pers. comm.). The major morphological
difference between Ceriporia pierii-group and Ceriporia viridans-group
(where C. alachuana belongs) is in the shape of spores: ellipsoid
to cylindrical in former and cylindrical and curved in latter (Miettinen et al.
2016). However, the shape of spores in our specimen was mostly slightly
but distinctly curved and the shape of spores is perhaps more variable
than expected before. Therefore, the species can be often misidentied
(possibly as C. alachuana) and more widespread. There are no published
records of C. pierii from Slovakia, but we collected another specimen in
Slovak mountains (Biele Karpaty Mts.) in 2017 and it was also found by
L. Hagara in Zvolen in 1998 (P. Vampola pers. comm.).

A yellow-coloured resupinate polypore originally described from Italy
(Bernicchia & Niemelä 1998). It is characterised by its bright yellow colour,
incrusted hyphae in subiculum and small ellipsoid spores. Zmitrovich et
al. (2006) transferred Ceriporia sulphuricolor to Gloeoporus, but the only
sequence available (isolated from Chinese specimen) is rather distant
in phylograms from this genus (e.g. Yuan et al. 2016, Chen et al. 2020)
and would be better placed elsewhere. However, European material of C.
sulphuricolor should be sequenced rst before any further taxonomical
changes are proposed. The second record outside Italy is from Rusovce
in Slovakia (Hagara 2014) and it was also found on several localities in
Portugal (Abrego & Salcedo 2011) and was reported also from China
(Dai 2012).
The species was described from a cavity in wet Pinus stump in otherwise
dry xerothermic locality (Bernicchia & Niemelä 1998, A. Bernicchia pers.
comm.). While the rst Slovak specimen was also from coniferous wood
(see photo in Hagara 2014), our collection is from broadleaf wood (Tilia).
However, this is possibly not exceptional as Abrego & Salcedo (2011)
give all their records from broadleaf (Fagus) as well and its ecology is
substrate preference is therefore considerably wider. Similarly, to the
collection from the type locality, the substrate of our specimen was also
rather moist and fruitbodies were growing on the underside of thick Tilia
branches with direct contact with soil. Such obscure fruitbody occurrence
might be one of the reasons why this otherwise remarkable species is
infrequently collected.

An olive green coloured discomycete growing on strongly decayed wood
almost exclusively of broadleaved trees. The species seems to have two
preferred habitats in central Europe – in old montane beech and ravine
forests (the most the records from Slovakia come from them – e.g. Mihál
et al. 2011, Svrček 1962, Škubla 1998b, PRM) and in lowland oodplain
forests and alder carrs. Both habitats share a humid microclimate and
often an abundance of coarse woody debris. In Podunajská nížina
Lowland, two localities are reported by Lizoň (1982), further by Škubla
(1998a, 1999), there is another specimen from there depicted in Hagara
(2014) and it was also collected there by Z. Pouzar near Rusovce (PRM
902302).

The species differs from similar and common Coprinopsis atramentaria
(Bull.) Redhead, Vilgalys & Moncalvo primarily by strongly developed
orange-brown coloured veil (Orton & Watling 1979, Vesterholt 2012).
Some authors however treat it only as a variety of C. atramentaria (e.g.
Ludwig 2007) and further study would be needed to give more insight
into the complex. There are reports from other parts of Slovakia (Škubla
2003), but it was not previously collected in Podunajská nížina Lowland.

The species forms small fruitbodies, which are often numerous and cover
large areas of fallen trunks. This could provide hint for its identication
already in the eld. However, specimens from substrates of smaller
diameter could consist of only a handful of fruitbodies and consequently,
such collections may be hard to differentiate from other small Crepidotus
species. In any case, microscopic characters – particularly capitate
cheilocystidia and trichoderm pileipellis structure with capitate terminal
elements are reliable for identication (Consiglio & Setti 2008).
Originally described from Crimea, Ukraine (Consiglio & Setti 2008, Prydiuk
2005) it was later found also in Austria and Slovakia (Jančovičová et al.
2014) and Czech Republic (Řepka et al. 2017, Salaš 2015). While records
from Austria and the Czech Republic have been from lowland oodplain
forests (Jančovičová et al. 2014, Salaš 2015), previous Slovak records were
from montane beech forests only (Jančovičová et al. 2014). The species is
also included in Red book of Dolní Morava (CR, Řepka et al. 2017).

Rarely reported small discomycete, the only species of the genus
restricted to Fraxinus (Groves 1946, Mehrabi et al. 2018), usually growing
on recently dead branches. There are several new localities in the Czech
Republic (Halasů 2019). This species was either probably overlooked
there or it is spreading due to ash dieback in past decade. In Podunajská
nížina Lowland, we recorded the species only in its anamorphic state.

40 Catathelasma 21 December 2020 December 2020 Catathelasma 21 41
An orange coloured corticioid fungus with worldwide distribution
(Hjortstam & Ryvarden 2007, Liu & He 2018) but generally with only
sporadic records in Europe (Bernicchia & Gorjón 2010). Its distribution
in Europe seems to be very uneven: according to Boidin & Gilles (1994)
it is not uncommon in marches in the western France and there are
numerous localities in Mecklenburg-Vorpommern in Germany (DGfM,
Hagara 2014), but it is very rare in rest of Central Europe. In Slovakia,
it was repeatedly recorded from Šúr NNR (Hagara 2014, PRM, BRA)
in Podunajská nížina Lowland and in addition also from Latorica PLA
in south-east Slovakia (www.nahuby.sk). While Slovak localities are from
southern parts of the country, there are European records much further
north e.g. near St. Petersburg in Russia (Volobuev & Arzhenenko 2018).
This is not rare at Šúr but only in the inner (and the most humid) parts
of alder carr on fallen trunks of Alnus often close to the ground, perhaps
requiring stable humid microclimate or periodical ooding. In contrast
to alder carr in Šúr, we did not nd D. effuscatum in oodplain forests,
however it was reported from such habitat by Tortić (1983) in Serbia.

Šúr NNR, willow scrub, attached branch of Salix, 6.XI.2018, leg. et
det. TT & LZ, HR B002798
A rather inconspicuous stromatic pyrenomycete growing on corticated
wood of broadleaves mostly from Salicacae family (Granmo et al. 1999).
According to our experience from the Czech Republic it is not rare in wet
Salix scrubs as well as on disturbed sites dominated with Salix caprea,
however there is only single Slovak record by Škubla (2003). As there
are several records also from Austria (Dämon 1996, Vasilyeva & Scheuer
1996) we suspect it is only overlooked in Slovakia.
Episphaeria fraxinicola (Berk. & Broome) Donk
Ostrovné lúčky NR, willow-poplar oodplain forest, fallen branch of
Fraxinus, 4.XI.2019, leg. TT & LZ, det. LZ, HR B002631
Very small cyphelloid fungus growing in association with old pyreno-
mycetes mostly on Fraxinus wood with attached bark (Krieglsteiner 2001,
Petersen & Læssøe 2019) but also on other broadleaved trees such as
Acer pseudoplatanus (Friebes 2018). To our knowledge, this is the rst
published record from Slovakia, but the species is probably overlooked
everywhere. Some authors confused it with Phaeosolenia densa (Berk.)
W. B. Cooke (Siepe & Kasparek 2002) that is microscopically similar, but
it forms tubular fruitbodies and, at least in central Europe, it is seemingly
restricted to Populus (Siepe & Kasparek 2002, Zíbarová 2019).

A corticioid fungus characterised by hyphal pegs and peculiar ecology,
i.e. growing on the leaf sheaths of sedges (Carex spp.) or of other

42 Catathelasma 21 December 2020 December 2020 Catathelasma 21 43
monocotyledons in wet habitats. It was considered a rarity in the Czech
Republic, but it is not uncommon in suitable habitats (Zíbarová & Kříž
2016). It is probably overlooked as herbaceous plants are rarely examined
by corticiologists. There is only single Slovak record of E. typhae known
to us (Veľké Leváre near Malacky – Hagara 2014, BRA), but we believe it
would be found on other localities if sought after in a tall sedges vegetation
and in alder carrs. While this species is not lignicolous, it was included
here for the sake of a completeness of the list of corticioid fungi.

Originally we identied the species as Flammocladiella decora (Wallr.)
Lechat & J. Fourn a species reported as parasitic on Massaria inquinans
(Tode) De Not. (Lechat & Fournier 2018), but the host of our collection was
different – Massaria anomia (Fr.) Petr. After a month after our collection a
second species of the genus – Flammocladiella anomiae was described

46 Catathelasma 21 December 2020 December 2020 Catathelasma 21 47
(associated with the same host) from Bulgaria and France (Lechat et al.
2019). Slovakia is therefore a third country for this new species.

Flammulaster limulatus is a rare bright coloured species found mostly in
old-growth natural forests. It is included in Red Lists of several countries
and it is often listed among species indicating nature value of beech
forests (Beran et al. 2016, Christensen et al. 2005). However, its ecology
is broader. Kříž (2018) published a recent collection from old Populus
alba and Juniperus dominated forest on dunes in Hungary. Previously,
Hagara (2014) reported it from two localities in Podunajská nížina
Lowland. There are described several close species (or varieties) and
both our specimens t Flammulaster limulatus var. limulatus according to
Vesterholt & Rald (2012).

Flammulaster muricatus is a species with similar ecology to preceding
and it is in our experience more common also at lower elevations, e.g.
it was reported from oodplain forests at the Morava and the Dyje
conuence in the Czech Republic (Antonín et al. 2000). However, both
our specimens differ from “typical” F. muricatus of old-growth beech
forests in unusually gracile fruitbodies and only nely granulose pileus
and stem surface. First, based on macromorphology we considered
Flammulaster gracilis as possible candidate for identication, but that
species differs from our collections in spores without a germ-pore and
spindle-shaped cystidia (Ludwig 2001, Hausknecht & Krisai-Greilhuber
2013). In fact, there are not any signicant differences in microscopical
characters between our specimens and beech morphotype of
Flammulaster muricatus. Similar collection was illustrated e.g. by
Ludwig (2001, 25.6C) considered a demonstration of the wide plasticity
of the species. We think the matter might still need further taxonomic
investigation, but it is beyond scope of this study.

As noted by Kotlaba & Pouzar (2009) specimens of G. resinaceum
from very humid habitats could be distinctly stipitate and therefore
hard to distinguish from G. lucidum, and the authors suggest that the
best distinguishing character in these cases is much coarser spore
ornamentation in G. lucidum. We can conrm their observations
and a DNA sequence of one our specimens (HR B002833) matches
G. resinaceum (M. Tomšovský pers. comm.).

A corticioid fungus reported from the wood of broadleaves (Boidin et al.
1997) characterised by clampless hyphae and mostly bisporic basidia
(Bernicchia & Gorjón 2010). It is the only species with bisporic basidia
in Gloeocysdiellum s. str.; according to Boidin et al. (1997) it is in fact
parthenogenetic species. In central Europe G. bisporum has been
recorded only in Germany (Ostrow & Dämmrich 2010, DGfM 2020).

This odontoid corticioid species macroscopically reminds a common
Brevicellicium olivascens. However, strongly amyloid ornamented spores,
gloeocystidia and incrusted terminal elements in aculei are striking
combination of microscopic characters. Other species of Gloeodontia
have either smooth hymenium or dimitic hyphal system (Chen et al.
2020, Telleria et al. 2008, Zhou & Dai 2013). Originally described from the
British Columbia, Canada (Burdsall & Lombard 1976), G. columbiensis
is rare in Europe collected mostly in southern countries (Bernicchia &

Resupinate corticioid species with waxy fruitbodies and persistent sweet-
chemical odour. While Škubla (2003) did not presented any records from
Slovakia, there are more than ten specimens from Slovakia deposited in
PRM mostly from colline to submontane levels, typically from localities of
high conservation value, but none from Podunajská nížina Lowland. In
our experience, it prefers hard decorticated wood in initial stages of decay
and substrates of our records from Podunajská nížina Lowland are in line
with that. Curiously, one of our record is from non-native Platanus sp.

also on other hosts (Bernicchia & Gorjón 2010, Hugill & Lucas 2019,
Krieglsteiner 2000), growing typically on very hard decorticated wood. In
central Europe, it seems to have similar distribution as other species (e.g.
Lopadostoma pouzarii, Rhodotus palmatus) associated with Ulmus such
as (sub)montane ravine forests and lowland oodplain forests. It was
found also in Marcelová in Podunajská nížina Lowland and Botianský

At rst sight the Hericium coralloides on Populus alba in oodplain forest
was a small surprise to us, because the species is considered as an
emblematic species of old-growth beech forests. This is however a good
example how our limited eld experience based mostly on situation in
Bohemia (Czech Republic), could be misleading; there are other reports
of Hericium coralloides from oodplain forests (Antonín et al. 2000, Dvořák
& Hrouda 2005) as well as from wood of Populus alba (Bernicchia 2001).

A heterobasidiomycete with stereoid, effused-reexed basidiocarps that
stains red-brown when bruised. It was described by Bresadola (1897)
based on collection by Slovak naturalist A. Kmeť, but largely forgotten
and placed under synonymy with Heteroradulum (Eichleriella) deglubens,
from which it differs by tendency to form pilei and dimitic hyphal system
with brownish skeletal hyphae (Malysheva & Spirin 2017). There is a
rich material in BRA collected by Kmeť in 19th century, but its current
distribution in central Europe is largely unknown (there is a single recent
record from Austria mentioned by Malysheva & Spirin 2017). According
to Malysheva & Spirin (2017) it is restricted to Salicaceae and prefers dry,
open habitats. Our records show it is not uncommon also in Populus alba
dominated oodplain forests.

We have already published a record of H. mastrucata (Tejklová &
Zíbarová 2018) but the fruitbody was senescent and mouldy there were
doubts about its identity. Meanwhile, we collected two good specimens
from other localities and conrmed that the species is present and more
widespread in oodplain forests in Slovakia.
Hydropus occipes (Fr.) Singer – [AU: LC:ec]
Šúr NNR, alder carr, fallen trunk of Alnus, 6.XI.2019, leg. et det. TT
& LZ, HR B002432
A rare mycenoid species with brown occose stem and globose spores.
It grows on (frequently mossy) wood of broadleaves, but also wood
remains, soil or peat (Læssøe 2012, Ludwig 2001), mostly in damp
forests, frequently alder carrs (Læssøe 2012, Petersen & Læssøe 2019),
it prefers shaded oak trunks in Białowieża (Holec et al. 2019). We found
it on several mossy trunks (often in large numbers) of Alnus in Šúr in
2019. In contrast, there are also records from dry oak forests in Southern
Europe and North Africa (Laganà et al. 1999, Outcoumit et al. 2014) and
its ecology is therefore considerably wider. The only record in Austria
is from greenhouse in Vienna (Hausknecht et al. 1997). In the Czech
Republic, it is considered as a diagnostic species for oodplain forests
indicating higher nature value of the habitat (Beran et al. 2016) and it is
included in Red book of Dolní Morava (EN, Řepka et al. 2017). We are
not aware of any previous record of H. occipes from Slovakia.

Čunovské jazerá, willow-poplar oodplain forest, strongly decayed

It is close to Hydropus (Mycopan) scabripes (Murrill) Singer that
differs by not having an incrusting pigment in pileipellis and has less
differentiated terminal elements in pileipellis (Læssøe 2012, Ludwig
2001, Bas 1999). Recently, Gminder (2013) described very similar
Hydropus longicystidiatus Gminder based on single record from Jena
botanical garden, differing mostly by macroscopic characters (shape and
striation of the pileus, colour and presence of pustules on stem). While
our specimen has indistinct pustules on stem, in other means (particularly
wrinkled, non-striate pileus) it ts to the concept of H. trichodermus.

differences in pileipellis was described from hardwood oodplain forest
along Danube river in Austria (Hausknecht et al. 1997). The authors note
there are some other specimens with habit similar to var. lobauensis from
the same locality, but with tetrasporic basidia and clamps (which they
reluctantly ascribe to var. trichodermus). Our Slovak collection matches
those tetrasporic specimens similar in habit to var. lobauensis. The whole
complex probably needs through revision as noted by Læssøe (2012).
Hydropus trichodermus is a widespread but very rare species in Europe
(Pérez de Gregorio Capella & Picón González 2011, Læssøe 2012).
According to Ludwig (2001) it is found mostly in montane forest on conifer
logs and stumps, but also on bark of beech and on the ground under
alder, oak and elm. There are records not directly associated with wood
such as on calcareous soil (Læssøe 2012) or sand dunes under pines
(Pérez de Gregorio Capella & Picón González 2011). From the Czech
Republic, it is listed by Holec (1992) on Abies alba from beech forests
of Šumava mountains, but its identication is uncertain (J. Holec pers.
comm.). It could grow also in man-made habitats e.g. on lawn strewn with
numerous woody debris (Grobelny & Ferville 2012) and ower beds in an
urban habitat (Freléchoux & Consolini 2013).
Škubla (2003) presents a single record of H. trichodermus from Slovakia,
but, after our revision of the corresponding specimen in BRA, we believe
it is most likely a misidentication and the specimen corresponds to
Mycena sect. Fragilipedes. Therefore, this is likely the rst report of the
species from the country.

A corticioid species with odontoid hymenophore. Hyphodermella rosae is
a southern species in Europe closely allied to Hyphodermella corrugata
(Fr.) J. Erikss. & Ryvarden distinguished by shorter basidia and smaller
spores (Telleria et al. 2010). The species has not been reported in central
Europe, probably not being distinguished from Hyphodermella corrugata.
We revised specimens of H. corrugata in BRA and stated that signicant
fraction (all of which is from southern, warm areas) agrees with concept
by Telleria et al. (2010) of H. rosae. We assume H. rosae is not rare in
areas of thermophilous vegetation in Slovakia. In our experience, it is the
most common aphyllophoralean species on Clematis vitalba in oodplain
forests in Slovakia, more frequent than Litschauerella clematidis (Bourdot
& Galzin) J. Erikss. & Ryvarden.

An easily identiable pyrenomycete by its characteristic stellate margin of
stromata restricted to Fraxinus spp. (Ju & Rogers 1996). It was reported
from Slovakia (Holíč) for the rst time as Hypoxylon moravicum Pouzar
by Pouzar (1972). It is recently spreading in central Europe, possibly as
consequence of ash dieback and climate change (Zíbarová & Kout 2017,
Zíbarová 2018a). Despite the presence of both suitable substrate and
habitat, we did not nd it in Podunajská nížina Lowland prior publication
of the rst paper (Tejklová & Zíbarová 2018). There is not any published
records nor any deposited specimen of the species in public herbaria from
the area. However, the recent records show, that Hypoxylon cercidicola
is present in oodplains forest in Podunajská nížina Lowland, yet it is
not as common there as we assumed at rst. Still, we have to search
for Hypoxylon fraxinophilum Pouzar with similar ecology there. Stromata
of H. cercidicola have typically very few or none developed perithecia
(Pouzar 1972) observed also in our Slovak specimens.

A bright yellow (reddish when bruised) resupinate fungus with strikingly
variable hymenophore. One of our specimens has hydnoid and the other
one poroid hymenophore (collected just ca 25 m apart). L. trachyspora
is a rare species in central Europe. It has somewhat enigmatic ecology,
it was reported from various substrates including wood, bark vegetation
debris and mosses (Bernicchia & Gorjón 2010, Legon 2012). The
previous Slovak records are from lowland oodplain forests – including
the rst record from Podunajská nížina Lowland – and from mountains
(Hagara 2001b) as well.

A resupinate corticioid fungus with hymenophore conspicuously
pubescent with abundant protruding cystidia. All of our records in
Podunajská nížina Lowland were collected on dead wines of Clematis
vitalba, but there are several similar specimens of Litschauerella spp.
(some are labelled as Litschauerella abietis) from Slovakia deposited

72 Catathelasma 21 December 2020 December 2020 Catathelasma 21 73
in PRM, all of which are from coniferous wood (Abies, Taxus) in higher
elevation. Such ecological divergence could suggest more species in
the group, supported by huge variability in spore size and ornamentation
noted by Eriksson & Ryvarden (1974). However, the same authors in
more detailed study (Eriksson & Ryvarden 1977) later concluded that
despite such variability, there is only one yet highly variable species
present. Nobody investigated the subject further in depth since. We
believe further study using molecular techniques would be desirable.

In our previous paper (Tejklová & Zíbarová 2018) the species was
reported as collected on wood of Pyrus. Meanwhile, we performed
a xylotomic analysis of substrate and concluded it was in fact Ulmus, like
our in other records of the species from Slovakia.

A small often stipitate annual polypore growing on angiosperm wood,
often partially on buried roots or twigs (Ryvarden & Melo 2017). For
a long time Šúr NNR, was the only known locality of the species in
Slovakia, where the species was repeatedly collected from the 1960s
(Kotlaba & Pouzar 1976, Škubla 1994, 1996, PRM, BRA). Most records
there are from wet alder carr (Kotlaba & Pouzar 1976) but according to
Škubla (2003) there is a collection from is oak-dominated xerothermic
part (Panónsky háj). Our specimen was not directly from the alder carr
but rather its mixed fringe with signicant proportion of Ulmus, Acer and
Fraxinus. We discovered the species just in the third year investigating
Šúr probably because of small and short-lived fruitbodies of L. fractipes
that were possibly already decomposed in November during our previous
autumn visits. It was collected also in Sihoť island (Jančovičová 1999).

A rare thermophilic polypore easily identied by cinnamon colours and
strong coumarin-like scent (Ryvarden & Melo 2017). Originally described
from Slovenia (David & Tortić 1979), Slovakia is on the north-western limit
of distribution of the species. It was not reported from the Czech Republic,
Germany or Poland, but there are numerous localities in Austria, mostly
in its south-eastern parts (Pidlich-Aigner & Höllrieg 2006). It is also
known from Hungary (Kutszegi et al. 2016). While Metuloidea fragrans
is usually associated with thermophilous Fagus forests (Kutszegi et al.
2016, Vampola 2011) there are some localities also in oodplain forests
in Podunajská nížina Lowland (Kotlaba 1984, BRA, PRM) and Záhorská
nížina Lowland (Škubla 1995).

The species forms fruitbodies in the shape of small aculei often growing
gregariously on the underside of fallen wood of both broadleaves and
conifers, typically on the humid localities. There are only handful of records
in Slovakia (Škubla 2003, BRA), none of which is from Podunajská nížina
Lowland. Probably the species is only overlooked due to hidden growth
and small size or confused with Mucronella bresadolae (Quél.) Corner
with larger fruitbodies and spores and is often associated with brown
rotted wood of conifers.

Šúr NNR, alder carr, base of the snag of Alnus, 6.XI.2019, leg. TT &
LZ, det. LZ, HR B002439
Similar to the common Mycena galericulata, from which it differs mainly by
less translucently striate pileus often with isabella tint, lack of mealy odour
and taste, shorter spores and almost smooth hyphae in pileipellis and
stipitipellis (Aronsen & Læssøe 2016). While it is considered a southern
species (Aronsen & Læssøe 2016, Ludwig 2012), in central Europe it is
often found in mountains (e.g. Komorowska 2010, Holec et al. 2015).
It was reported from the Bukovské vrchy Mts. by Červenka (2016) and
we discovered it is in montane mixed natural forests in Slovakia in 2019
(Majdanová et al. unpublished data), where could be locally common. We
found only one single collection deposited as Mycena romagnesiana in
BRA, however we found another one originally determined as Hydropus
sp. (Sekanina in Vysoká Fatra Mts.). The photo of Mycena galericulata in
Hagara (2014, p. 687) from Badínský prales virgin forest represents typical
M. romagnesiana as noted by Holec & Dvořák (2015). We suspect there
are more further specimens misidentied as M. galericulata from Slovakia
in BRA and PRM and the species is largely overlooked in Slovakia.

A small inconspicuous heterobasidiomycete parasitic on pyrenomycetes,
mostly Botryosphaeria spp. and its anamorphic states (McNabb
1965, Piątek 2002). The species was also reported as Platygloea
miedzyrzecensis in past (McNabb 1965), however, the Czech specimens
of P. miedzyrzecensis mentioned by Pilát (1957) are in fact Dacrymyces
ovisporus (Wojewoda 2002). As we did not nd any published records
or specimens of N. sebacea (or its synonyms) from Slovakia in herbaria,
this is the likely rst record of the species from the country.

records from the Czech Republic (Zíbarová & Kout 2017), but it has not
been published from Slovakia till now but there are several unpublished
specimens in PRM, including one from Podunajská nížina Lowland
(Rusovce, in insula supra portum, PRM 821106).

An effused stromatic pyrenomycete, differing from similar European
Nemania species already in macroscopic characters – even fully mature
stromata are often not entirely black retaining some brown colour and the
perithecial mounds are very inconspicuous, so the species might remind of
Hypoxylon spp. It seems to be uncommon thermophilic species in central
Europe (Zíbarová & Kout 2017). There are several record of N. diffusa all
collected by Z. Pouzar (determined as N. bipapillata) deposited in PRM
from warmer regions of Slovakia and single one from Podunajská nížina
Lowland (“Velký ostrov apud. Karlova Ves”, i.e. Sihoť). Microscopically
similar N. carbonacea has conspicuous perithecial mounds and white
tissue between stromata (Ju & Rogers 2002).

Rather inconspicuous odontoid corticioid species with rhizomorphs in
macroscopical aspect reminding Trechispora farinacea. Its microscopical
characters are also rather nondescript – small elliptic, smooth and
inamyloid spores, no cystidia, terminal elements in aculei not incrusted,
hyphae thin-walled, without clamps. It was described from Argentina,

84 Catathelasma 21 December 2020 December 2020 Catathelasma 21 85
but it was recorded in Germany (Hjortstam & Ryvarden 1986) and later
reported from Colombia (Hjortstam & Ryvarden 2007) France and Italy
(Bernicchia & Gorjón 2010). Molecular comparison of South American
and European material would be interesting.

A resupinate corticioid species with conspicuous septocystidia. It was
only a single record in the Czech Republic (Pouzar 2006), but then it was
collected in more localities, but still mostly in natural forests with ample
dead wood (e.g. Antonín et al. 2014, Zíbarová 2018b). It was reported
from more localities in Austria (Dämon & Krisai-Greilhuber 2017). It
was published from Slovakia and Podunajská nížina Lowland (2015) by
Hagara (2014) and there are two more collections from the same locality
in BRA and additional two collections from other parts of Slovakia (L.
Hagara pars. comm.). We collected the species at three localities within
a few days in November 2018, but had not seen the species before or
since. This experience highlight often underappreciated importance of
phenology and year-to-year variability in corticioid fungi.

A whitish gilled fungus with strong mealy odour and narrowly spaced
lamellae. It was not distinguished from Ossicaulis lignatilis for a long
time. Both species are distinct – mostly in spore size but (to some
extent) also in ecology – O. lignatilis prefers man-made habitats and O.
lachnopus natural forests (Holec & Kolařík 2012). We revised material of
O. lignatilis sensu lato from Podunajská nížina Lowland deposited in BRA
and found out that both species are present there, even from the same
locality – there are both species among collections of L. Hagara around
Rusovce. Sadly, the specimen from Rusovce corresponding to photo (as
O. lignatilis) in Hagara (2014, p. 803) is sterile.

Small fully resupinate annual polypore often with strongly lacerate to
spathulate tubes. It was referred as Oxyporus phladelphi (Sell et al. 2014,
Vampola 1991) before. It was rst reported from Slovakia by Vampola
(1991) collected in Velká Fatra in 1953 and later by Hagara (2014)
from Podunajská nížina Lowland (Rusovce). It is reported from various
substrates – wood of both broadleaves and conifers as well as vines
and herbs (Vampola 1991, Michel et al. 2005, Hagara 2014). Two of our
records are from Clematis vitalba, the only polypore we found on this
vine. While O. millavensis is considered very rare in central Europe (apart
from Slovakia it is reported only from the Czech Republic – Ryvarden &
Melo 2017, Vampola 1991). It is probably overlooked there and mistaken
for common Schizopora radula (Pers.) Hallenb. in the eld.

An uncommon corticioid species growing frequently on attached dead
branches Ulmus spp. There is only one other published record from
Slovakia ‒ Latorický luh NNR in South-east Slovakia (Hagara 2014).
In neigbouring countries, the species was reported mostly from lowland
oodplain forests (Dämon & Krisai-Greilhuber 2017, Wojewoda 2000,
Zíbarová & Tejklová 2020), but there are records also from ravine forests
in Austria too (Dämon & Krisai-Greilhuber 2017). For further notes on
its distribution and ecology in Slovakia and the Czech Republic see
Zíbarová & Tejklová (2020b).

A cyphelloid fungus with small tubular fruitbodies that can form extensive
groups. It is restricted to Populus spp. in central Europe (Siepe &
Kasparek 2002, Zíbarová 2019), often growing in cracks of bark of dead
branches (1–2 years dead) and seems to be a typical species of poplar-
dominated lowland oodplain forests. In Slovakia, it was rst collected
by Z. Pouzar in 1970s in Podunajská nížina Lowland but misidentied as
Phaeosolenia granulosa (Fuckel) W. B. Cooke (PRM 776545).

A resupinate corticioid species with hydnoid hymenophore. The species
was described from Iran and has worldwide distribution including Southern
Hemisphere (Martinez & Nakasone 2005) and Hawaii (Gilbertson et
al. 2001). Hjortstam & Ryvarden (2010) synonymised Phanerochaete
aculeata with Phanerodontia magnoliae (Berk. & M. A. Curtis) Hjortstam
& Ryvarden but for time being we follow Bernicchia & Gorjón (2010) and
treat both species separate. P. aculeata is generally rare in Europe, it was
previously reported from Slovakia by Hagara (2014) from Podunajská
nížina Lowland (“Číčov, Lionské rameno”).

A resupinate corticioid fungus with hydnoid hymenophore and trimitic
hyphal system. It is a rare species in central Europe, there are reported
only two records from neigbouring Austria (Dämon & Krisai-Greilhuber
2017) and a single one from the Czech Republic (Zíbarová 2017).
There is one published record also in Podunajská nížina Lowland in
Slovakia (Hagara 2014) – Chotínské piesky NR near Komárno. It was
also collected in eastern Slovakia (Slanské vrchy Mts., L. Hagara pers.
comm.). For further discussion on ecology, distribution and taxonomy
see Zíbarová (2017).

A conspicuous and well-known resupinate corticioid fungus with veined
hymenophore and often pink mbriate margin. In central Europe, it
was considered a rarity of natural montane forests before. According
to our experience from the Czech Republic, the species seems to be
spreading also into lower elevations in past two decades. Our records
from Podunajská nížina Lowland (the rst from the area) supports this
assumption.

A resupinate corticioid species with variable, often strongly veined
hymenophore that is conspicuously pruinose with projecting metuloid
cystidia. It is very rare species in Europe, reported only from few countries
(Bernicchia & Gorjón 2010), there is single record from Austria (Dämon
& Krisai-Greilhuber 2017) and three localities in the Czech Republic,
all in oodplain forests in Southern Moravia (Řepka et al. 2017). It was
reported from Podunajská nížina Lowland (Šúr NNR) by Hagara (2014),
who noted that the species prefers humid or inundated habitats, and our
records are in agreement with this. However, its habitat associations are
wider in North Europe and Russia including r, spruce and pine forests
(Eriksson et al. 1981, Zmitrovich & Ezhov 2011), nevertheless it seems
to be restricted to old-growth forests (Zmitrovich & Ezhov 2011). The
species is included in Red book of Dolní Morava (EN, Řepka et al. 2017).

A peculiar heterobasidiomycete with capitate fruitbodies reminding of
myxomycete and with odour of lovage (Levisticum ofcinale). It has
scattered distribution in central Europe – almost common is some areas
but absent in others. From Podunajská nížina Lowland (Gabčíkovo), it

96 Catathelasma 21 December 2020 December 2020 Catathelasma 21 97
was reported already by Pilát (1957). A distribution map in Slovakia was
published by Ripková et al. (2004). We found the species only at Dunajské
ostrovy NR but it was abundant on many fallen trunks (Populus alba, Acer
negundo). There is also a record from oodplain forests in Latorica PLA
in south-east Slovakia (Škubla 1997b). In the Czech Republic, it was also
published from oodplain forests at conuence of Morava and Dyje rivers
(Antonín et al. 2000) We have not record it at other localities or even
during our repeated visits to the same locality. As noted by Holec (2003),
P. faginea might need specic course of weather during year to produce
fruitbodies. It has rather broad ecological preferences as being reported
from various trees (most often Carpinus – Holec 2003, Ripková et al.
2004, Szczepkovski et al. 2008) from both natural and man-inuenced
habitats (Szczepkovski et al. 2008).

A conspicuous species characterised by stout fruitbodies, pilei with grey
brillose squamules and very pale spores for the genus (Kits van Waveren
1985, Ludwig 2007). Currently the species is placed in Coprinopsis
(Örstadius et al. 2015). It is a rare southern species in Europe (Ludwig
2007). P. melanthina seems to have synantropic distribution in central
Europe – it was reported from a park near Budapest (Babos & Szuecs
1979) and most Austrian records are clustered around Vienna (ÖMG
2020). Škubla (1995, 2003) presents only one locality from Slovakia
(Bratislava-Petržalka) and it is not listed in Psathyrella checklist of
the Czech Republic and Slovakia by (Vašutová 2006). According to J.
Červenka (pers. comm.) it is not rare around Bratislava and during our
excursion in November 2018 it was quite frequent in poplar-dominated
oodplain forests.

Radulomyces rickii (Bres.) M. P. Christ. – [AU: DD]
Kopáčsky ostrov NR, hardwood oodplain forest, thin trunk of
Clematis vitalba, 13.IV.2018, leg. TT, LZ & AP, det. LZ, HR B002859
A resupinate corticioid fungi with thin waxy basidiomata. It could be
distinguished from close Radulomyces conuens (Fr.) M. P. Christ. by
spore shape (globose in R. rickii, broadly ellipsoid in R. conuens) and
wider basidia (Bernicchia & Gorjón 2010, Ghobad-Nejhad & Kotiranta
2007). Basidiospores in R. rickii are usually nely warted, but this
character is sometime present also in R. conuens. The basidiomata
are hygrophaneous – i.e. bluish grey and semi-translucent when wet,
creme with some orange tint and opaque while dry in both species.
R. rickii has southern distribution in Europe (Bernicchia & Gorjón 2010).
Its distribution in Slovakia is unknown, as it was not distinguished from the
very common R. conuens (e.g. Škubla 2003 gives both as synonyms).
We have another record from Malé Karpaty Mts. (Kuchyňa), also on
Clematis.

A small gregarious discomycete lacking both bright orange tints and

A very rare species in Slovakia, the only other record from Podunajská

in Hagara (2014) also from Podunajská nížina Lowland (Rusovce) is

Sihoť PA, willow-poplar oodplain forest, fragment of a trunk Populus,
7.XI.2018, leg. TT & LZ, det. LZ, HR B002744
A small olivaceous gilled species with often eccentric stem. It could
be distinguished from similar Simocybe haustellaris (Fr.) Watling by
the presence of inated elements in pileipellis and strongly capitate
cheilocystidia (Hausknecht 2012, Senn-Irlet 1995). In the Czech
Republic it was reported from oodplain forests at conuence of the
Morava and the Dyje rivers (Antonín & Vágner 1993), in Austria, it was
reported from mixed broadleaf and oodplain forests often together with
Crepidotus crocophyllus, Arrhenia discorosea and Pluteus chryophaeus
(Hausknecht 2012). While in the Czech Republic it was collected on
Ulmus (Antonín & Vágner 1993), the record from Switzerland (Senn-Irlet
1995) as well as our current record are on Populus. In our specimen the
numerous fruitbodies grew hidden in the concave part of the underside of

110 Catathelasma 21 December 2020 December 2020 Catathelasma 21 111
fragment of poplar wood and would be overlooked if we would have not
deliberately looked under pieces of wood searching for corticioid fungi.
This is probably the rst report of S. coniophora from Slovakia, but it
might be overlooked there to its hidden growth and confusion with much
more common S. haustellaris.

A thin resupinate corticioid species with conspicuous gloeocystidia
and clampless hyphae. It is reported from both Northern and Southern
Hemispheres (Greslebin 2001, Hjortstam 1987, Martínez & Nakasone
2010), but rare in Europe (Bernicchia & Gorjón 2010). It was not previously
known from Podunajská nížina Lowland, but there are records from
nearby Malé Karpaty Mts. (Hagara 2014, Škubla 2003). It is reported
from wood both of broadleafs and conifers in various types of habitats
probably preferring humid sites with abundant dead wood.

Sistotrema subtrigonospermum D. P. Rogers
Šúr NNR, alder carr, fallen trunk of Populus, 15.IV.2018, leg. TT & LZ,

An inconspicuous resupinate corticioid fungus with very characteristic
tetrahedral spores. The species has worldwide distribution (Hjortstam
& Ryvarden 2007, Jülich & Stalpers 1980) but it is very rare in Europe
and it is reported only from a few countries (Bernicchia & Gorjón 2010).
We recorded the species in Šúr NNR almost 50 years after this was
collected there by Z. Pouzar (Hagara 2011). It seems that even rare,
it can survive on locality for long time. Šúr remains the only locality of
S. subtrigonospermum in Slovakia. The species was collected both on
broadleaf and conifer wood as well as herbaceous remnants in various
types of habitats (Boidin & Gilles 1994, Eriksson et al. 1984, Hagara
2011).

6-spored basidia, thick-walled ellipsoid spores, clampless hyphae
and presence of gloeocystidia (Bernicchia & Gorjón 2010, Boidin &
Gilles 1994). It is very rare species in Europe and it was not recorded
in Slovakia before. Little is known about its ecology, it seems to prefer
broadleaf wood in humid habitats (Daniëls & Moreno-Arroyo 2008, Losi
1999, Ordynets et al. 2012).

A thin greenish-gray to olive species with conspicuous subcapitate
cystidia (Kõljalg 1996). Apparently a rare species (Čížek 2009, Kõljalg
1996), a photograph of the species from Podunajská nížina Lowland was
published by Hagara (2014). Other three specimens from warm regions
of Slovakia (Slovenský kras, Štiavnické vrchy, Zemplínské vrchy) are
included in herbarium of K. Čížek (now part of HR).

We published records of Tomentellopsis pusilla in previous paper
(Tejklová & Zíbarová 2018), but the revision of more material including

120 Catathelasma 21 December 2020 December 2020 Catathelasma 21 121
sequencing of ITS region of rRNA gene was done and the specimens are
better placed in T. pulchella. The difference between the two species is
small, beside colour and size of basidia the major difference is the shape
of spores (Kõljalg et al. 2009). We compared our specimens with those of
T. pusilla in collection of K. Čížek (now in HR) and we are not convinced
there is clear difference between both species. However, because our
specimens from Slovakia t the description of T. pusilla better (colour,
spores shape), we use this name for our collections now. Nevertheless,
detailed molecular study of the genus is needed.

While this polypore is rare in more temperate parts of the central Europe,
it is more frequent in warmer parts of the region e.g. in south-east Austria
(Dämon & Krisai-Greilhuber 2017), and judging from abundant material
in BRA also in colline level in Slovakia. It was previously collected in
Podunajská nížina Lowland by L. Hagara (Rusovce, in BRA).

A rare corticioid species with conspicuous brownish chlamydospores
in subiculum. It was originally described by Pilát (1942) as Tomentella
smardae from present-day Czech Republic (and not collected there
for another 59 years – Kotlaba & Pouzar 2014). A monotypic genus
Trechinothus was later proposed for the species (Martini & Trichiès 2004)
based on its unique micromorphology. Its taxonomic placement is still not
clear (it shows afnities both to Trechispora and Lindtneria – Martini &
Trichiès 2004) as there is no sequence available in public databases. We
have repeatedly tried sequencing our collections but without success until
now. It is a very rare species in Europe reported only from few countries
(Lucas & Rogerson 2018) and this is the rst collection from Slovakia.

Sihoť PA, hardwood oodplain forest, fallen thin trunk of Tilia,

A resupinate corticioid species with an odontoid hymenophore. It differs
from similar Trechispora species by long basidia and presence of

124 Catathelasma 21 December 2020 December 2020 Catathelasma 21 125
anamorphic state with ovoid conidia (Bernicchia & Gorjón 2010). While
widespread, it is rare in Europe. Collection by Hagara (2014) from Malá
Fatra Mts. is probably the only record from Slovakia published before.
It has probably broad ecology as it was reported both from broadleaves
and conifers (Bernicchia & Gorjón, Hagara 2014, Liberta 1973) and we
have collected it in the Czech Republic both from wet and dry habitats.

A rare annual polypore reported only from few countries in Europe
restricted to annually ooded areas (David & Duhem 1986, Ryvarden

2004). It was published by Vampola & Pouzar (2006) from two localities
in Podunajská nížina Lowland – at Somola near Vlčany (right bank of
Váh river) and near Klúčovec (oodplain forest at left bank of Danube).
In Šúr it was previously collected by V. Kunca (pers. comm). It could be

A thin resupinate fungus growing on dead mostly decorticated wood
of broadleaves, typically Swida sanguinea in central Europe. Previous
records in Slovakia are only from south-western parts of the country
(PRM). The species has strongly declined in central Europe (listed as
extinct in Poland from which it was described, Wojewoda & Ławrynowicz
2006) possibly due to air pollution or climate change. For more detailed
discussion of its ecology and distribution see Zíbarová & Tejklová (2020a).

A pyrenomycete with fasciculate digitate stromata originating from
a common rooting base. The species, even often misidentied, was not
perhaps rare in 18th a 19th centuries, but there are only few records in
past century (Fournier 2014, Læssøe 1992). There are several records of
Xylaria digitata from 19th century in BRA, however only single collection
(leg. A. Kmeť, 10 Sept. 1888, Prenčow) seems to agree with the current
concept of the species. The species (as Hypoxylon digitatum) is listed
among Fungi of Bratislava by Bolla (1857), but its identity is uncertain
(see above). It was collected by Z. Pouzar near Topoľčany (PRM) in
1985. The photograph published in as Xylaria digitata from Slovakia
Mihál & Blanár (2014) shows an anamorphic state of Holwaya mucida
(Schulzer) Korf & Abawi (= Crinula caliciiformis (Fr.) Fr.). There are some
recent records also along Danube in Austria (ÖMG 2020). Both our
records were from the base of dying large Populus alba, possibly growing
from roots. The species was also recently collected by R. Maňák (pers.
comm.) on Populus alba in south Moravia, the Czech Republic.

Conclusions
We recorded 438 taxa during our eld trips in 2018, 2019 and 2020, 259
of which were not included in our previous article (Tejklová & Zíbarová
2018). Of all taxa, corticioid fungi (excluding tomentelloid species)
were the most numerous with 114 taxa recorded in total. Of remaining
Basidiomycetes, 88 could be classied as polypores, 72 as gilled fungi,
17 as tomentelloid fungi, 17 as jelly fungi, 10 as cyphelloid fungi and
9 other. In Ascomycetes, we determined 39 taxa of discomycetes and
72 taxa of pyrenomycetes. In general, we recorded a greater proportion
of gilled (and other eshy and short-lived) fungi than in 2016–2017,
possibly due to the warmer weather (before the onset of frosts) during
our November trips.
Many of the recorded species are rare in Slovakia with signicant
proportion being found only in Podunajská nížina Lowland and we have
to stress that the area needs urgent protection – in the rst place from the
inappropriate forestry (mis-)management of old-growth oodplain forests
(clear-cutting) we have witnessed at many localities.
