INTRODUCTION
This article presents the new and noteworthy
ndings of lichens and allied fungi from the Len-
ingrad Region and St. Petersburg continuing the
series of publications on the same subject (see
e.g. Kuznetsova et al., 2007; Stepanchikova et
al., 2010a, b, 2011a, b; Himelbrant et al., 2016).
The lichens Bacidina brandii, B. neosquamulosa,
Porina leptalea, Rinodina aspersa and licheni-
colous fungus Scutula dedicata are reported for
the rst time for Russia, lichenicolous fungus
Lichenoconium aeruginosum – for European Rus-
sia, while the lichen Tetramelas chloroleucus,
lichenicolous fungi Lichenoconium pyxidatae
and Tremella cetrariicola are new for the North-
Western European Russia. Ten of the reported
taxa (the lichens Alyxoria culmigena, Bacidina
egenula, Dermatocarpon miniatum var. miniatum,
Lecanora fuscescens, Rhizocarpon viridiatrum,
Thelocarpon impressellum, lichenicolous fungi
Echinothecium cladoniae, Libertiella curvispora,
Taeniolella beschiana, and saprobic fungus
Pyrenula coryli) are new for the whole Lenin-
grad Region (including St. Petersburg), and one
(Niesslia cladoniicola) – for St. Petersburg.
MATERIAL AND METHODS
Specimens were collected by Dmitry E. Himel-
brant, Irina S. Stepanchikova, Ekaterina S.
Kuznetsova, Aleksandra V. Dyomina, Ludmila
V. Gagarina, Ludmila A. Konoreva and Gulnara
M. Tagirdzhanova in 2004–2016 in the eastern
and western parts of Leningrad Region or in St.
Petersburg, and are deposited in the lichen her-
baria of St. Petersburg State University (LECB)
and Institute of Botany, Nature Research Centre
in Vilnius (BILAS). Furthermore, we investigated
several specimens of lichens and lichenicolous
fungi kept in the herbaria of University of Helsin-
ki (H), University of Turku (TUR-V), Finnish For-
est Research Institute (HFR) and Samara State
University (SMR). Mentioned specimens were
mainly identied by the authors of the paper,

The names of the main collectors in the spe-
cies list are abbreviated as follows: AD – Alek-
sandra V. Dyomina; DH – Dmitry E. Himelbrant,

Vainio, IS – Irina S. Stepanchikova, VR – Veli
Räsänen. The subdivision of the Leningrad Re-
gion (LR) was published in our previous paper
(Stepanchikova et al., 2010b); the following ab-
breviations have been used here: ELR – Eastern
Leningrad Region, SPb – St. Petersburg, WLR
– Western Leningrad Region. The biogeographi-
cal provinces of Eastern Fennoscandia are ab-
breviated traditionally (Kotiranta et al., 1998):
Ik – Isthmus karelicus, Ka – Karelia australis,
Kl – Karelia ladogensis, Kol – Karelia olonetsen-
sis. Lichenicolous fungi are marked with # and
non-lichenized fungi with +. The nomenclature
of taxa generally follows Nordin et al. (2011);
for the species not mentioned in the checklist,
special papers are cited (Wedin et al., 2006;

(Stepanchikova et al., 2011). Distribution in
North-Western European Russia outside of LR:
not reported. Distribution in Fennoscandia and
Baltic countries: not reported.
# echinothecium clAdoniAe Keissl. – ELR,
Podporozh’e District, ca. 16 km N to Vachozero
Lake, 61°14’10.4”N, 34°12’14.6”E, old-growth
spruce forest with birch, Sphagnum spp., Erio-

AD & Ekaterina I. Rozantseva (BILAS). – New
to LR. Distribution in North-Western Euro-
pean Russia outside of LR: Republic of Karelia
(Zhurbenko & Himelbrant, 2002). Distribution
in Fennoscandia and Baltic countries: Norway,
Sweden, Finland (Nordin et al., 2011). The fun-
gus is similar to Niesslia cladoniicola, differing
by smaller (50–65 μm diam. in our specimen)
ascomata, short (macroscopically inconspicu-
ous) setae with rounded apices and walls much
darker than ascomatal walls and hyaline as-
cospores that may turn pale brown. Ascospores
were 12.0–13.0 × 4.0–4.5 μm in our specimen,
hyaline to very pale brown, all 1-septate [no
simple spores seen, as described by Zhurbenko
& Pino-Bodas (2015)]. Characteristic feature
of E. cladoniae is brown supercial mycelium,
however, it is not macroscopically visible when
growing on sorediate podetia, as was in case of
our specimen: the mycelium was seen only in
microscopic preparations.
lecAnorA fuscescens (Sommerf.) Nyl. – WLR,
Ka, Vyborg District, former Patalahti, ca. 3 km
NW of Kamennogorsk (former Antrea), 60°58’N,

Osmo H. Porkka (H). – New to LR. The report of
this species from Gumbaritsy, Lodeynoe Pole
District, Kol, ELR (Elfving, 1878) belongs to L.
boligera (Norman ex Th. Fr.) Hedl. (see Kuznet-
sova et al., 2007). Distribution in North-Western

29.07.2016, leg. AD (BILAS). – New to LR. Dis-
tribution in North-Western European Russia
outside of LR: Republic of Karelia (Fadeeva et al.,

countries: Finland (Nordin et al., 2011), Estonia
(Randlane et al., 2016), Lithuania (Motiejūnaitė

# lichenoconium Aeruginosum Diederich, M.
Brand, van den Boom & Lawrey – WLR, Gatchina
Region, vicinity of Ermolino, 59°29’58.4”N,
29°41’42.5”E, boulder on meadow, on thallus
of Cladonia cf. mbriata (L.) Fr. on primary
soil on granitic boulder, 06.10.2016, leg. DH &
IS (BILAS). – New to European Russia except
Caucasus. Recently reported from Russian
Caucasus (Zhurbenko & Kobzeva, 2016). Dis-
tribution in Fennoscandia and Baltic countries:
not reported. The fungus is easily distinguished
from all species of the genus by the presence of
bluish pigment in pycnidial wall and by strong
aeruginose reaction with K of pycnidial walls
(Lawrey et al., 2011). Apart from the striking
reaction of pycnidial wall, from all the species
of the genus that occur on Cladonia, L. aerugi-
nosum differs by larger conidia.
# lichenoconium pyxi dAtA e (Oudem.) Petr. &
Syd. – ELR, Boksitogorsk District, ca. 3 km E
of Krasnoborsky, 59°57’22.2”N, 35°15’35.1”E,

Norway, Sweden (Nordin et al., 2011), Estonia
(Randlane et al., 2016), Latvia (Motiejūnaitė et
al., 2016), Lithuania (Motiejūnaitė, 1999). From
most of the species of the genus occurring on
Cladonia, L. pyxidatae differ by rather large
pycnidia (100–130 × 70–95 μm in our specimen)
and rather smooth, truncate conidia (Diederich,
2004). For the differences from L. aeruginosum
see above.

on Tuckermannopsis, forming reddish brown to
black brown convex basidiomata, usually with
central depression when old (Diederich, 1996).
In our specimen ellipsoid basidia with longitu-
dinal to oblique basidia and basidiospores with
refractive apiculus were observed.
