INTRODUCTION
Arctic-alpine agarics are known to occur in the arctic areas of Europe, Asia and North America. In
Europe, a substantial amount of data has been gathered for the Alps while much less is known about
the distribution of this group of fungi in other alpine areas. Very few records are available from the
Carpathians, and no mycological investigations have been carried out in the alpine areas of the south-
ern and eastern parts of this mountain range to date. The main objective of this work is to present the
first records of fungi collected in the alpine zone of the Southern Carpathians (Romania). Special
attention is paid to the arctic-alpine element.
STUDY AREA
The Carpathians constitute a major mountain system in Europe. Situated in the south-eastern part of
the continent, they extend through Slovakia, Poland, Ukraine and Romania (Fig. 1). Approximately
55% of the range belongs to Romania, covering almost 30% of its territory (Ronikier 1996a). The
Carpathian Mts are divided into three parts: the Western Carpathians (Slovakia and Poland), the Eastern

Carpathians (Poland, Slovakia, Ukraine and Romania), and the Southern Carpathians (Romania). The
latter constitute a mountain chain about 320 km long running from the east to the west. They reach the
Predeal pass (1033 m) in the vicinity of Braşov in the West and the gorge of the Donau river, called
Porţile de Fier in the East (Ronikier 1996b). A characteristic feature of the Southern Carpathians is a
high average altitude; 10 % of the area reaches more than 2000 m a.s.l. Because of intensive pastoral
culture developed in the Romanian Carpathians, alpine and subalpine meadows cover extensive
areas in the mountain landscape, extending down to relatively low altitudes (Ronikier 1996b), at the
expense of subalpine dwarf pine forests and patches of Rhododendron myrtifolium Schott et Kotschy
and Juniperus communis L. ssp. alpina (Sm.) Čelak.
The Southern Carpathians are composed of several well differentiated massifs: Munţii
Făgăraşului, Munţii Iezer–Păpuşa, Munţii Leaota, Munţii Bucegi, Piatra Craiului, Munţii Parîng,
Munţii Căpăţinii, Munţii Lotru, Munţii Cindrel, Munţii Latoriţei, Munţii Sebeşului, Munţii Retezat,
Munţii Ţarcu, Munţii Godeanu, and some smaller ones. One national park is established in the Southern
Carpathians, Parcul Naţional Retezat, and three other parks are planned; in Munţii Bucegi, in Piatra
Craiului and in the small massif Cozia situated between Munţii Făgăraşului and Munţii Lotru (Soran
et al. 2000). Several areas are protected as nature reserves.
Six main massifs were studied: Munţii Făgăraşului, Munţii Iezer–Păpuşa, Munţii Bucegi, Munţii
Lotru, Munţii Cindrel and Munţii Latoriţei (Fig. 1). The vegetation of these massifs is conditioned
on the bedrock. Munţii Bucegi and Munţii Latoriţei are built up of limestone-rich rocks. Typical
calcareous ectomycorrhizal plant species, such as Salix reticulata L. and Dryas octopetala L., are
abundant in the former massif while they are completely absent throughout the latter. The other four
massifs are mostly granitic. The Iezer-Păpuşa, Lotru and Cindrel Mts. are dominated by poor, crys-
talline-bedrock grasslands. Salix herbacea L. and Polygonum viviparum L. occur there as the only
mycorrhizal hosts. In Munţii Făgăraşului, there are many places richer in nutrients, especially along
the edges of the main ridge cliffs and in schistous slopes; Salix reticulata and Dryas octopetala are
often encountered.
MATERIAL AND METHODS
Extensive field work was carried out in the alpine belt of the Southern Carpathians in July and August
2004.
Most collections of fungi were made by Anna Ronikier and Michał Ronikier (AR, MR); some
collections were made by Elżbieta Cieślak (EC) or Jakub Cieślak (JC). The entire material is deposited
at the Herbarium of the Institute of Botany, Polish Academy of Sciences, Cracow (KRAM).

RESULTS
About 200 collections were made during the field work of which 77 have been examined for this
paper. A total of 24 species have been identified, of which 11 are arctic-alpine and 13 species are
typical grassland species (Hygrocybe spp.) or ubiquitous species that occur in various habitats and
also frequently in the alpine zone. Fourteen species have not previously been reported from Romania

and from the Southern Carpathians: Amanita nivalis, Hygrocybe turunda, Inocybe alboperonata,
I. dulcamara, I. microfastigiata, I. nespiakii, I. oreina, Lactarius brunneoviolaceus, L. nanus, Li-
chenomphalia alpina, Mycena citrinomarginata, Russula heterochroa, R. nana, R. saliceticola. Five
species: Inocybe alboperonata, I. microfastigiata, I. oreina, Lactarius brunneoviolaceus, and Russula
heterochroa are new to the Carpathians.
DISCUSSION
Over 2000 species of Basidiomycetes are known to occur in Romania (Bontea 1985). Results of my-
cological investigations in the Romanian Carpathians have been reported in numerous publications;
those, however, focus mostly on microfungi or forest macrofungi. The body of data on macrofungi
recorded in Munţii Bucegi is fairly substantial (Kotlaba 1959, Eliade 1961, 1963, 1964, Eliade &
Toma 1977), and some records from Munţii Leaota (Toma & Diaconescu 1971) and Retezat (Pop
1989) are also available. Only three species of macrofungi are, however, encountered in the altitude
between 1800 and 2500 m in Munţii Bucegi; listed under the names “Deconica coprophylla (Fr. ex
Bull.) Karst, Amanitopsis vaginata (Bull.) Roze and Lactarius rufus (Scop.) Fr.” (Eliade 1963). To
the best of my knowledge, no previous published information exist on alpine fungi of the Southern
Carpathians. Thus, the present paper provides the first well documented observations of fungi from
the alpine zone of the Southern Carpathians. It clearly demonstrates that these mountains host a fungal
flora that is fairly rich in species of this ecological group of fungi.
Russula nana was the most common species in alpine areas in the Southern Carpathians. Al-
though found only in two massifs, it was very common, occurring not only with dwarf shrubs (Dryas
octopetala and/or Salix spp.) but also in those areas where Polygonum viviparum was the only present
potential mycorrhizal partner. The species is also known from the Western Carpathians, where it is
one of the most frequent arctic-alpine fungi.
Three species of Lichenomphalia were also encountered in the Southern Carpathians with

high frequency. Lichenomphalia hudsoniana, which is also very frequent in the Western Carpathians
(Lisicka 1999, Olech 2004), was the most common of these species. L. alpina is known only from
few localities in the Western Carpathians.
Some rare species of fungi are reported for the first time from the Southern Carpathians. Rus-
sula heterochroa is a very rare species, reported only from the French Alps and Swedish Lapland,
while Inocybe nespiakii is known from the Alps and the Western Carpathians. Inocybe alboperonata
had previously been reported from alpine zones of the Alps and the Pyrenees. These three species
were found in the Munţii Bucegi or Munţii Latoriţei massifs. These two calcareous regions of the
Southern Carpathians as well as the others not yet investigated within the present project seem to be
the most promising among Carpathian areas with respect to fungal species richness, due to presence
of many rare, calciphilous species.
The data collected are insufficient to acquire a general picture of the distribution of fungi in
both the Southern Carpathians and the entire Carpathian system, but some indications emerge. As the
alpine (and also subalpine) meadows cover extensive areas in the Southern Carpathians, high richness
of fungi associated with grassland vegetation can be expected in the area. Furthermore, high diversity
of bedrock types, giving rise to variation in edaphic conditions, results in the occurrence both of spe-
cies requiring nutrient-rich soils and species that prefer oligotrophic sites. This environmental and
vegetational variability suggests that this region has a potential for high fungal species richness.
COMMENTED LIST OF SPECIES
Amanita nivalis Grev.
Observations. Four carpophores were found growing in one place, on a large stone covered with a
soil layer and Salix retusa. One carpophore (KRAM F-54854) had a greyish cap without veil rem-
nants and a pure white volva while three others (KRAM F-54853) had a paler beige cap covered
with numerous small volval warts with an ochraceous tinge and a pale brownish spotted volva. All
specimens had white pruinose-floccose stipes without any girdles. Macroscopic and microscopic
features of the collected specimens are consistent with the detailed description provided by Knudsen
& Borgen (1987).
Notes on distribution. Amanita nivalis is known from arctic and subarctic areas of Finland,
Greenland, Norway, Sweden, Russia (Polar Urals), from the Faroe Islands, Iceland and Scotland,
alpine zones of the Norwegian mountains as well as the Swiss, French, Italian, Austrian and German
Alps, the Pyrenees and the Western Carpathians (Favre 1955, Lange 1955, Gulden & Lange 1971,

Amanita nivalis had not previously been reported from Romania; however, Amanitopsis
vaginata (Bull.) Roze” is listed among fungi found at the altitude 1800–2500 m in Munţii Bucegi
(Eliade 1963). This record may belong to A. nivalis.

Hygrocybe psittacina (Schaeff.: Fr.) P.Kumm.
Notes on distribution. Like the three species mentioned above (Hygrocybe chlorophana, H. conica
and H. pratensis), Hygrocybe psittacina is a widespread species which also occurs in subarctic and
subalpine-alpine meadows (Boertmann 2000).
Specimen examined. Munţii Latoriţei, N-W slopes of the Vf. Fratoşteanu Mare peak, alpine pasture on calcareous

reddish (6A8, 7A8, 8A8) paling to yellow-buff (4A5) pilei covered with dark violet-brown, almost
black (11F3–4, 12F3) squamules and by pale yellow (2A5), decurrent lamellae.
Taxonomic notes. The macro- and microcharacteristics of the specimens are consistent with
the descriptions given by Boertmann (2000) and Borgen & Arnolds (2004).
Notes on distribution. The fungus has a boreal-montane, low alpine to (sub-) arctic distribu-
tion (Borgen & Arnolds 2004). The species is new to Romania.

Inocybe alboperonata Kühner
Fig. 2.
Description. Cap 1–2 cm in diameter, campanulate with prominent umbo and decurved margin,
greyish brown, clay-buff, dark greyish buff (5C3–4, 5D3–4), surface covered with white veil giving
fibrillose-squamulose appearance, darker brown under veil. Lamellae greyish yellow, beige (4B3,
4C3), moderately distant, adnate, up to 3 mm broad, edge whitish ciliate. Stipe 2–5 × 0.4 × 0.6 cm,
cylindrical, white when young because of a thick layer of white veil, isabella (5D6) under veil, not
pruinose or only at extreme apex. Flesh whitish, smell spermatic, taste mild.
Spores amygdaliform with conical apex, 9.5–12 × 5.5–6 µm. Basidia 31–35 × 8–11 µm, with 4
sterigmata. Cheilocystidia cylindrical to fusiform, 60–104 × 11–18 µm, walls 1–1.5(2.5) µm. Pleuro-
cystidia similar, 50–110 × 11–25 µm, scattered. Caulocystidia not well developed, rare, present only
in extreme apex of the stipe, cylindrical, fusiform or lageniform, 70–140 × 11–26 µm.
Taxonomic notes. A discussion of closely related taxa is provided by Esteve-Raventós & Vila
(1998).
Ecological notes. Inocybe alboperonata is considered to be a calciphilous species associ-
ated with Salix and Dryas (Esteve-Raventós & Vila 1998). The Carpathian record accord with the
anticipated ecological preferences of the species: it was also found on limestone, with Polygonum
viviparum as the only potential mycorrhizal host.
Notes on distribution. Inocybe alboperonata has been reported from the Alps (Kühner 1988)
and the Pyrenees (Esteve-Raventós & Vila 1998). The species is new to the Carpathians and Roma-
nia.

Inocybe microfastigiata Kühner
Fig. 3.
Description. Cap 1.5–2 cm in diameter, conical, straw yellowish brown, honey-coloured
(4B4–6) with darker, yellowish brown centre (5D7), surface rimose, margin decurved in young speci-
mens and white ciliate because of veil remnants. Lamellae pale greyish-yellow (3B4), moderately
crowded, adnate, broad. Stipe 2–2.5 × 0.3 × 0.4 cm, cylindrical or subbulbose, white, longitudinally
fibrillose, apex pruinose. Flesh white, pale ochraceous at base, smell herb-like, taste none.
Spores ellipsoid, subphaseoliform 11–12 × 6–7 µm. Basidia 35–37 × 10–11 µm, with 4 sterig-
mata. Pleurocystidia absent. Cheilocystidia cylindrical, narrowly clavate, thin-walled, some septate,
35–55 × 9–12 µm. Caulocystidia present only at stipe apex, cylindrical, thin walled, very long, up to

Notes on distribution. Inocybe microfastigiata is known from the Swiss, French and Italian
Alps (Kühner & Lamoure 1986, Bon 1992, Jamoni & Bon 1995). However, as the taxonomy of the
Inocybe fastigiata group is in need of revision, the actual geographical distribution of I. microfastigiata
is not known. The species is new to the Carpathians and Romania.

depressed centre, yellowish brown, brownish olive (5D6–7, 5E6–7), surface tomentose, fibrillose or
slightly squamulose. Lamellae yellowish buff (4C6, 4C7), then brownish (4F8, 5F8), moderately
crowded, adnate, broad. Stipe 1–1.5 × 0.3 × 0.5 cm, cylindrical, honey-coloured (4B4, 4B5), without
distinct remnants of veil, longitudally fibrillose, hollow. Flesh whitish chrome (3A2), without smell
and taste. Veil inconspicuous.
Spores ellipsoid-cylindrical, 10–14(15) × 5–6 µm. Basidia 35–42 × 10–11 µm, with 4 sterigmata.
Cheilocystidia cylindrical to broadly clavate or almost spherical, 25–38 × 10–20(36) µm.
Taxonomic notes. The name I. nespiakii was created by Bon (1996) as a replacement for the
invalid name I. favrei described by Nespiak (1990). I. nespiakii is considered to be an alpine species
(Bon 1997). Although Nespiak described the species on the basis of Favre’s alpine collection of I.
dulcamara f. aff. malenconii (Favre 1955), he selected a type collection from the subalpine spruce
forest of the Tatra Mts. (Western Carpathians). I. nespiakii is very similar to I. malenconii Heim var.
megalospora Stangl & Bresinsky. According to the original description (Nespiak 1990), the former
species is characterized by lack of a distinct cortina (stipe surface is covered by fibrils which do not
form any trace of a ring), while the latter taxon has a very well developed veil (Stangl 1989). In the
description of I. nespiakii provided by Bon (1997), the stipe of the species is “fibriloso-laineux” or
has a thick cortina. The typical I. malenconii has a distinct but fugacious cortina (Heim 1931). As the
presence or absence of cortina seems to be a variable feature, it cannot be excluded that I. nespiakii is
conspecific with I. malenconii var. megalospora and I. malenconii. Bizio (1997) reports I. maleconii
from the alpine zone. He also points out the differences between I. malenconii and I. nespiakii, and
notices that their similarity makes the distinction between the two species very difficult.
Notes on distribution. Inocybe nespiakii is known from alpine habitats of the Swiss and French
Alps (Favre 1955, Kühner & Lamoure 1986, Bon 1991). I. malenconii reported from the alpine zone
of the Italian Alps (Bizio 1997) may be conspecific with the Carpathian specimens examined. The
species is new to Romania.

Lichenomphalia alpina (Britzelm.) Redhead, Lutzoni, Moncalvo & Vilgalys
Notes on distribution. Lichenomphalia alpina is a typical arctic-alpine species widely distributed
but not as common as L. hudsoniana. It is known from arctic-subarctic areas of Sweden, Norway,
Finland, Russia, Canada, Alaska, from Svalbard, Greenland, Iceland, the Faroe Islands, Scotland,
alpine zones of the Norwegian mountains and the French and Swiss Alps (Favre 1955, Lange 1955,
Miller 1968, Bigelow 1970, Gulden & Lange 1971, Watling 1977, Lamoure et al. 1982, Watling
1983, 1987, Hansen & Knudsen 1992, Lamoure 1993, Vesterholt 1998, Niezdoiminogo 2003, G.
Gulden, pers. comm.). Lichenomphalia alpina has also been reported from the Western Carpathians
(Bujakiewicz 1993, Flakus & Bielczyk 2006) but it seems to be very rare there. The species is also
known from the Andes in South America and from lowland sites (Gulden et al. 1985). The species
is new to Romania.

Lichenomphalia hudsoniana (H.S.Jenn.) Redhead, Lutzoni, Moncalvo & Vilgalys
Notes on distribution. Lichenomphalia hudsoniana is one of the most common arctic-alpine spe-
cies occurring mainly in the alpine zone and arctic areas, but descending to subalpine and subarctic
belts. It has also been reported from lowland sites in Denmark (Gulden et al. 1985). The species is
known from arctic and subarctic areas of northern Norway, Sweden and Finland, from Svalbard,
Greenland, the Faroe Islands, Scotland, Alaska, northern Canada, Russia, North American mountains,
Norwegian mountains, the Swiss Alps and from the alpine zone of South American mountains (Favre
1955, Lange & Skifte 1967, Bigelow 1970, Gulden & Lange 1971, Watling 1977, Lamoure et al.

Mycena citrinomarginata Gillet
Observations. The collected specimens are characterized by yellow brownish, greyish yellow colours
(4B6, 4C4–5) of the cap which was darker in the centre and almost white at the margin, by yellow
lamella edges and numerous lageniform to fusiform cheilocystidia which are simple or with a few
short or long, apical or lateral, simple or branched excrescences.
Notes on distribution. Mycena citrinomarginata probably represents the montane-boreal ele-
ment as it occurs more often in boreal regions and mountainous habitats than in lowlands. It is also
frequently recorded in arctic areas and alpine zones. In the Western Carpathians, it has been found
in the subalpine zone a number of times. The species is new to Romania.

Russula nana Killerm.
Observations. Russula nana was the most frequently encountered species in the alpine zone of the
Southern Carpathians. The fungus has no special preferences regarding either the edaphic condition
or the mycorrhizal host. It occurred on calcareous and siliceous bedrock, and grew together with
Salix spp., Dryas octopetala or Polygonum viviparum. Although recorded only in two massifs so far,
it should also be found in other regions.
Notes on distribution. Russula nana is one of the most common arctic-alpine species occurring
in arctic areas of Norway, Sweden, Finland, Russia, Canada, Greenland, the Faroe Islands, Scotland,
Alaska, Svalbard, Iceland, in the alpine zone of the Norwegian mountains, the Polar Urals, the Swiss,
French, Austrian, Italian and German Alps and the Pyrenees (Favre 1955, Horak 1960, Lange &

Russula saliceticola (Singer) Kühner ex Knudsen & T.Borgen
Notes on distribution. Russula saliceticola is known from alpine and arctic-subarctic habitats in
Norway, Sweden, Finland, Greenland, Iceland, the Faroe Islands, Swedish and Norwegian mountains,
the Swiss, French and German Alps (Favre 1955, Kühner 1975b, Knudsen & Borgen 1982, Lamoure
et al. 1982, Schmid-Heckel 1985, Bon 1991, Hansen & Knudsen 1992, Vesterholt 1998, G. Gulden,
pers. comm.). Russula saliceticola is also present in the Western Carpathians (Fellner & Landa 1993,
Knudsen & Ronikier 2003). The species is new to Romania.

ACKNOWLEDGEMENTS
I am greatly indebted to Michał Ronikier for his help in collecting, describing and photographing fungi
in the field. Special thanks are also due to Catalin Tănase (Iaşi, Romania) for his help in gathering
Romanian literature, to Pierre-Arthur Moreau (Lille, France) for his remarks on Inocybe microfastigiata
and assistance with literature, and to a reviewer for the insightful comments on the manuscript. This
study was partly carried out within the framework of the project financed by the Polish Ministry of
Education and Science, grant no. 2P04C 086 30. Field collection of fungi was financially supported
by grants from EU project INTRABIODIV (6th FP). The author’s attendance at the ISAM7 was sup-
ported by the Foundation for the Polish Science and Foundation for Polish Botany.

... However, detailed taxonomic studies of Arctic and alpine Russula species did not begin until the 1950s, mostly in Europe. For Arctic and alpine regions of Eurasia, Russula species have been reported from the European Alps (Kühner 1975;Jamoni and Bon 1993;Jamoni 1995Jamoni , 2008Bon 2000;Adamčík and Knudsen 2004;Knudsen et al. 2012;Adamčík et al. 2016), the Monte Rosa Massif (Bon 1993), the Pyrenean range (Bon and Ballarà 1996;Corriol 2008), the Tatra Mountains in the Western Carpathians Landa 1993a, 1993b;Adamčík et al. 2006Adamčík et al. , 2016Ronikier and Adamčík 2009), Fennoscandia (Favre 1955;Lange and Skifte 1967;Knudsen et al. 2012;Ruotsalainen and Huhtinen 2015;Adamčík et al. 2016), Germany (Bresinsky et al. 1980), Romania (Ronikier 2008), Scotland (Watling 1987;Fellner and Landa 1993b), and Russia (Knudsen and Mukhin 1998). Russula species have also been reported on the Arctic island of Svalbard (Kobayasi et al. 1968;Skifte 1989;Gulden and Torkelsen 1996) as well as more temperate regions of Iceland (Christiansen 1941;Hallgrimsson 1998) and the Faroe Islands (Vesterholt 1998;Adamčík and Knudsen 2004). ...
... Russula nana has been reported in the Alps, Pyrenees, or Carpathians (Favre 1955;Horak 1960;Kühner 1975;Lamoure 1982;Bon 1985Bon , 1987Bon , 1991Bon , 2000Kühner and Lamoure 1986;Bon and Cheype 1987;Senn-Irlet 1987;Schmid-Heckel 1988;Tondl 1988;Landa 1991, 1993b;Jamoni 1995Jamoni , 2008Adamčík 1998;Peintner 1998;Sarnari 1998Sarnari , 2005Bresinsky et al. 2000;Moreau 2002;Corriol 2008;Ronikier 2008;Gyosheva and Dimitrova 2011), Faroe Islands (Vesterholt 1998), Fennoscandia (Gulden and Lange 1971;Kühner 1975;Gulden et al. 1985;Graf 1994;Sarnari 1998Sarnari , 2005Ohenoja 2000;Gulden 2005), the Netherlands (Geml et al. 2014), Tatra Mountains (Ronikier and Adamčík 2009), Russia (Knudsen and Mukhin 1998;Niezdoiminogo 2003), Scotland (Watling 1987), Iceland (Hallgrimsson 1998), and Svalbard (Gulden et al. 1985;Skifte 1989;Gulden and Torkelsen 1996). In North America, R. nana has been reported from Alaska (Miller et al. 1973;Miller 1982), Canada (Ohenoja and Ohenoja 2010), Greenland (Watling 1977;Knudsen and Borgen 1982;Lamoure et al. 1982;Borgen 1993;Borgen et al. 2006), and the Rocky Mountains (Moser and McKnight 1987;Cripps and Horak 2008). ...
... Morphologically, R. saliceticola has been reported in Arctic and alpine areas of the European alps (Favre 1955;Kühner 1975;Schmid-Heckel 1985Bon 1991), Fennoscandia (Kühner 1975;Hansen and Knudsen 1992;Gulden 2005), Western Carpathians in Slovakia (Fellner and Landa 1993b;Knudsen and Ronikier 2003), Romania (Ronikier 2008), Faroe Islands (Vesterholt 1998), Greenland (Knudsen and Borgen 1982;Lamoure et al. 1982;Borgen et al. 2006), Iceland (Hallgrimsson 1998), and Svalbard (Skifte 1989). Knudsen and Borgen (1982) also thought that this species was described from the Alps as R. brunneoviolacea Crawshay (Singer 1936;Favre 1955). ...

Russula (Russulales) is an important ectomycorrhizal fungal genus in Arctic and alpine regions where it occurs with Salix, Betula, Dryas, and Polygonum, yet a complex phylogenetic analysis of the genus in these habitats is lacking. This research compared collections of Russula from the Rocky Mountain alpine (Colorado, Montana, Wyoming) with reference specimens from Arctic and alpine habitats, mostly in Europe, using an in-depth morphological study and a phylogenetic analysis of the nuc rDNA internal transcribed spacer region ITS1-5.8S-ITS2 (ITS barcode) and the second largest subunit of the RNA polymerase II gene (rpb2). One hundred thirty-nine Russula collections were sequenced, including type material. Ten species are reported from alpine or treeline habitats in the Rocky Mountains. This is the first formal report of R. cf. altaica, R. saliceticola, and R. subrubens from the Rocky Mountains and of R. purpureofusca in North America. Russula laevis is reported for the first time under this name with a voucher, and not as an environmental sample. Previous reports of R. nana and R. laccata are molecularly confirmed. Two species are reported from subalpine habitats at treeline: R. montana with conifers and R. cf. altaica with Betula. In this study, R. laccata, R. subrubens, and R. laevis were collected in alpine habitats but have been reported below treeline in Europe; these species may also be present at lower elevations in North America. Most species have an intercontinental distribution and have been reported in other alpine or Arctic habitats. Two unidentified and potentially new species were only found in North America and are discussed. A key to the alpine Russulas of North America is provided.
... Apart from arctic-alpine fungi, more ubiquitous species also occur in the alpine belt and are sometimes very common. H. conica is the most common species of Hygrocybe in the alpine belt of the Carpathians (Pilát 1969;Wojewoda 1996;Ronikier 2008) (Kubička 1964;Pilát 1969;Bujakiewicz 1993Bujakiewicz , 1996Bujakiewicz , 2004Ronikier 2008;Ronikier, Borgen 2010).

New localities of Hygrocybe salicis-herbaceae were observed during the research on the fungi of the alpine zone in the Carpathians. This is the first record of this arctic-alpine fungus in the South-Eastern Carpathians. Macro- and micromorphological characters of the Carpathian collections are compared with the descriptions from other regions. A revision of literature data indicates that the sites in the Parâng Mts. reported here are the only known localities of the species from the entire Carpathian range.
... The father of alpine mycology, Jules Favre, spent twenty-one years examining the mushrooms above treeline in the Swiss National Park, hiking to higher elevations to collect specimens (Favre 1955;Horak 1993;reviewed in Brunner et al. 2017). Other mycologists soon followed his example in the high Alps, Pyrenees, and Carpathians, including Bon (1985Bon ( , 1987Bon ( , 1991Bon ( , 1993, Kühner (1975), Lamoure (1982), Horak (1987aHorak ( , 1987b, Senn-Irlet (1987), Graf (1994), Peintner and Moser (1996), Jamoni (1995Jamoni ( , 2008, Bizio (1995Bizio ( , 1997, Ronikier (2008), and Corriol (2008).

Mushrooms and other fleshy fungi are important components of arctic and alpine habitats where they enhance nutrient uptake in plants and replenish poor soils through decomposition. Here we assemble the 200-year (1819–2019) record of their discovery in North America, beginning with early Arctic sailing expeditions, followed by intense taxonomic studies, and concluding with the molecular era, all of which highlight the difficulty of exhaustively revealing their biodiversity in these extreme, cold-dominated habitats. Compiled biogeographic data reveal that a majority of arctic fungi have large intercontinental distributions with disjunct alpine populations. A newly compiled checklist of 170 species of Basidiomycota in fifty-one genera and twenty families in the Rocky Mountain alpine zone provides current baseline data prior to expected environmental shifts.
... An excellent example of a biogeographically distinct and important group poorly known in the Carpathians compared with other major European mountain ranges are the arctic-alpine macrofungi of the alpine zone. Almost no data were available for the Carpathians until recently, when biogeographically informative reports on new and very rare species appeared (Moreau et al., 2006;Ronikier, 2008;Horak & Ronikier, 2011;Eberhardt et al., 2015). Recent studies allow now a first glimpse on the distribution of arctic-alpine macrofungi across the chain . ...

The Carpathians are the largest mountain range in Central Europe. Their geographical position, extent, isolation, landscape heterogeneity, well-preserved environment, and relatively low impact of Quaternary glaciations make them of utmost importance for studies on European biodiversity and biogeography. In this review, introducing a Special Issue of the Biological Journal of the Linnean Society, we provide an overview of current research and focus on three main aspects: (1) distribution patterns and species richness including endemism; (2) phylogeographical patterns, inference of major barriers, and divergence areas; and (3) cytological studies and cytogeography inferred from vascular plant polyploid complexes. Our survey shows that, although accurate estimation is not possible for several important taxonomic entities because of unavailable or dispersed data, the Carpathians are a clear hotspot of European diversity for many groups of organisms, such as mammals, breeding birds, amphibians, lichens, and vascular plants. Certain groups, not necessarily those with high species richness, are rich in endemic taxa. This holds mainly for subterranean invertebrates, molluscs, grasshoppers, beetles, spiders, and vascular plants. Distribution patterns of endemic richness vary across taxonomic groups, as well as geographically, reflecting both history and habitat features. In general, the SouthEastern Carpathians have a significantly higher proportion of endemic taxa than the northerly-situated Western Carpathians. Molecular clock-based estimations have provided some insight into the diversification age of the Carpathian biota, including a Tertiary origin for some endemic taxa and lineages, especially those confined to environmentally stable habitats. Distribution patterns, as well as phylogeographical and phylogenetic data, corroborate the persistence of many high-mountain and forest taxa during the Quaternary climatic oscillations, often in multiple spatially delimited areas isolated by physical barriers. Several studies show that the Carpathian massifs played an important role as refugia for rare lineages and/or as stepping stones in migrations. Phylogeographical analysis reveals clear patterns of biogeographical breaks, as well as links, although clear exceptions also confirm that extant distribution patterns are often shaped more by idiosyncratic processes acting at different geological times. Cytogeographical data also uncover several consistent patterns, which probably reflect a deeper evolutionary history. In conclusion, the available data highlight the unique position of the Carpathians in the evolution and preservation of European biota within the European Alpine System.
... Combined with the fact that Kühner's herbarium was practically not available before it was annexed to Geneve, it is not surprising that unanimous circumscription of these taxa was not reached. They have been included in some papers (Romagnesi 1985, Bon 1988, Sarnari 1998, 2005, Adamcík 2004, Adamcík & Knudsen 2004, Ronikier 2008, Knudsen et al. 2012 but the way they were described and the scarce original material have made interpretations difficult. Hence, fresh material collected in northern Fennoscandia has been difficult to name. ...

Based on a detailed study of holotypes, emended descriptions of two somewhat problematic species are given. Recent material of those taxa is also presented with colour photographs. Russula nuoljae and R. purpureofusca were both described by Kühner based on one or two fruitbodies collected from Scandinavian fjelds. R. cupreola is shown to be synonymous with R. purpureofusca.

Lactarius (Russulales) is an important component of ectomycorrhizal fungal communities in cold-dominated contiguous arctic and disjunct alpine habitats where it associates primarily with Betula, Dryas and Salix. However, little is known of this genus in the central and southern Rocky Mountain alpine zone (3000-3900 m) of North America. Molecular phylogenetic analyses of nuc rDNA ITS1-5.8S-ITS2 (ITS barcode) and the second largest subunit of the RNA polymerase II gene (RPB2) partial sequences in conjunction with detailed morphological examination confirm at least six species occurring above treeline. Most have intercontinental distributions in North America and Eurasia according to molecular comparison with type material and collections from Europe, Fennoscandia, Svalbard and Alaska. Rocky Mountain collections of L. lanceolatus (subgenus Russularia), along with the type from Alaska are paraphyletic with respect to L. aurantiacus and North American taxa L. luculentus and L. luculentus v. laetus. Rocky Mountain collections of L. nanus, L. glyciosmus, L. repraesentaneus and L. salicis-reticulatae (subgenus Piperites) all form clades with European material from type localities and other arctic-alpine habitats. The arctic-alpine L. pseudouvidus/L. brunneoviolaceus group appears to be a complex containing additional taxa. North American material originally described as part of this group is well-separated phylogenetically and is described here as L. pallidomarginatus sp. nov. Lactarius lanceolatus, L. nanus and L. salicis-reticulatae appear largely restricted to arctic-alpine habitats with Salix. Lactarius glyciosmus and L. repraesentaneus occur in arctic-alpine, subalpine and boreal habitats with Betula and also Picea and possibly Salix for the latter. Species distributions are hypothesized to be shaped by host ranges, glaciation and long distance dispersal.

Malíček, J., Bouda, F., Liška, J., Palice, Z. & Peksa, O. 2015. Contribution to the lichen biota of the Romanian Carpathians. — Herzogia 28: 713–735. We present floristic data from 82 localities mainly from eight mountain ranges of the Romanian Carpathians (Făgăraş, Parâng, Cindrel, Harghita, Hăşmaş, Bihor, Maramureş and Rodna). The main habitats investigated were subalpine and alpine communities, beech and spruce forests, and limestone areas at lower altitudes. During four field expeditions, 364 lichenized and three lichenicolous fungi were recorded. Thirty-seven taxa are new for Romania. Biatora subduplex, Helocarpon pulverulum, Lecanora filamentosa, L. flavoleprosa, Lecidea huxariensis, Leucocarpia biatorella, Myriospora dilatata, Pertusaria borealis, Placynthium dolichoterum, Reichlingia leopoldii, Rhizocarpon carpaticum and Vezdaea stipitata are new for southeastern Europe. Lecanora flowersiana is reported for the first time from Europe. Candelariella commutata, Cetrelia chicitae, Lecanora cinereofusca, Leptogium hildenbrandii, Psoroma tenue var. borealis, Rinodina roscida and Usnea longissima are either phytogeographically remarkable or very rare taxa.

Between 2002 and 2012 regular visits to the Carpathians were made and a number of Hebeloma spp. were collected from the alpine area. In total 44 collections were made that represent 11 species, two of which, Hebeloma grandisporum and H. oreophilum, are described here as new. Of the 11 species, four (H. alpinum, H. marginatulum and the two species described as new) are known only from alpine or Arctic habitats. Hebeloma dunense and H. mesophaeum are commonly found in, but not restricted to, alpine habitats. The other five species (H. aanenii, H. laterinum, H. naviculosporum, H. vaccinum, H. velutipes) are usually found in lowland or boreal habitats. Hebeloma naviculosporum is reported for the first time from the alpine zone and H. alpinum for the first time as growing with Helianthemum. All but two species (H. alpinum, H. marginatulum) are reported for the first time from the Carpathian alpine zone. In this paper we discuss the habitat, the 11 recorded species and give detailed descriptions of the two new species, both morphologically and molecularly. A key for Hebeloma species from sect. Hebeloma occurring in Arctic-alpine habitats is provided.
... Inocybe microfastigiata Kü hner was also collected near L. salicis-herbaceae. This small Inocybe species, which usually grows in association with dwarf willows, is found in the high-mountain belts of European mountains, having been reported in the Swiss, French and Italian Alps as well as in the Romanian southern Carpathians (Jamoni & Bon 1995; Ronikier 2008, among others). It represents a typical example of fungal alpine dwarfism as its basidiomes are much smaller (cap 1.5 – 2 cm in diameter, stipe 2– 2.5 £ 0.3 £ 0.4 cm) than those of the very similar species I. rimosa (Bull.) ...

A wide range of cold environments exist, with an equally broad variety of fungi and yeasts that have adapted to such environments. These adaptations, which affect membranes, enzymes and other cellular components, such as radical scavenging molecules, display a great potential for exploitation in biotechnology. Alterations have been detected in membrane lipids, with an increase in fatty acid unsaturated bonds that enhance their fluidity. We report new data on the different phospholipid composition in membrane lipids in the same fungal species from both Antarctic and temperate regions. The decrease in temperature causes intracellular oxidative stress by inducing the generation of reactive oxygen species. We report the results of the first analysis of the non-enzymatic antioxidant response and phenolic compound production by an Antarctic strain of Geomyces pannorum. A survey on yeasts from the cryosphere is reported with a focus on their adaptation to a cold environment. Some studies have shown that the number of macrofungi in glacier forefronts rises as deglaciation increases. The survival success of many plants in such areas may be attributed to their mycorrhizal associations. We highlighted the macrofungal biodiversity of some Italian alpine habitats, in which we Inocybe microfastigiata, Laccaria montana and Lactarius salicis-herbaceae were recorded for the first time in Lombardy (Italy).

A list of 102 larger fungi mainly associated with Betula pubescens in Greenland is given. Species from most of the major taxonomic groups of larger fungi are represented. The species have been classified into a number of broad mycogeographical types. It is concluded that the fungi associated with B. pubescens in the subarctic part of southern Greenland constitute a fairly large group of which 4/5 of the species are mainly distributed in temperate areas and 1/5 in subarctic or arctic areas.
Chapter
The larger Arctic-alpine fungi found in the islands and highlands of Scotland are considered and their distribution even at sea-level discussed in relation to climate, geology, soil and vegetation. Particular attention is paid to the distribution of Amanita nivalis, Russula spp. and Laccaria spp. , and Omphalina alpina and hudsoniana; Inocybe spp. , and Cortinarius spp. Larger ascomycetes and other basidiomycetes are briefly considered.

A first series of observations on the fungus flora of the alpine zone in mountains of Wyoming and Montana is presented here. Special attention is given to species of the genus Cortinarius. Thirteen species of this genus are discussed or described, 5 of them are new: Cortinarius absarokensis sp. nov., C. fuscoflexipes sp. nov., C. mucronatus sp. nov., C. rufoanuliferus sp. nov., and C. vulpicolor sp. nov. Several of the other species treated are new for North America, including Lactarius nanus Favre.

Favre (1955) reported 10 species (three varieties and one form) of Astrosporina (= Inocybe p.p.) from alpine habitats in the SNP and vicinity. Subsequently this publication became of paramount importance for the identification of arcto-alpine inocyboid agarics having brown angularnodulose spores. The critical revision of Favre’s authentic collections (CHUR, now in GC) revealed however, that several taxa were misidentified by Favre or the outlined taxonomic concepts do not correspond to modern interpretation. Based upon Favre’s material and additional personal topotypical specimens several taxonomical changes and corrections are proposed and discussed. At present, the following 14 species of Astrosporina are recorded from the alpine belt of the SNP where they are associated with dwarf willows (Salix spp.) and/or Dryas octopetala L. (* = new record for SNP): * A. alpigenes Hk. sp. n. * A. asterospora (Quél.) Rea (= I. napipes Lge. ss. Favre, mis ident.) * A. aurea (Huijsman) Hk. A. casimiri (Vel.) Hk. A. concinnula (Favre) Hk.

(= I. decipientoides var. taxocystis Favre) Illustrations and a key to the reported species of Astrosporina are presented. The results of the present revision emphasize not only the difficult delimitation and recognition of the arcto-alpine species of Astrosporina, but also the fact that the majority of their records (cf. list) require re-examination to assess their identity.
