The genus Rinodina (Ach.) Gray belongs to the family Physciaceae and comprises
approximately 300 species worldwide (Sheard, 2010; Wijayawardene et al., 2020). Ac-
cording to Nadyeina et al. (2011), Rinodina is polyphyletic and includes species with
crustose thallus, lecanorine apothecia, one-septate brown ascospores with inner wall
thickenings and Lecanora-type asci.
Rinodina is a difficult genus in terms of species identification due to the large va-
riety of spore types. Recent studies of the genus Rinodina in Russia (including the
Magadan Region), China, South Korea, and Japan have made a great progress in our
understanding of the diversity of this genus in the Northeastern Asia (Sheard, 2010;
Sheard et al., 2017). Sheard et al. (2017) reported many species which were previously
unknown in the Russian Far East. In addition, the authors also revealed the close re-
lationship between Asian and American species, including some that were previously
considered to be endemic to North America.
The genus Rinodina in the Russian Far East has been actively studied in the last
decade. However, the majority of studies are focused on the south of the area (Galani-
na et al., 2011, 2018, 2021; Galanina, 2013, 2016, 2019; Sheard et al., 2017; Galanina,
Ezkhin, 2018, 2019; Konoreva et al., 2018; Yakovchenko et al., 2018) while data on its
northern part (including the Magadan Region) remain rather poor (Korolev, Tolpy-
sheva, 1980; Kotlov, 1991, 1993a, 1993b, 1995, 2004), although some new species were
reported from the region as it is indicated below.
The first records of the genus Rinodina in the Magadan Region were made by Ko-
rolev and Tolpysheva (1980) who reported two species, R. archaea (Ach.) Arnold and
R. exigua (Ach.) Gray. Later, the species Rinodina hyperborea H. Magn., R. milvina
(Wahlenb.) Th. Fr., R. mniaroea (Ach.) Körb., R. sibirica H. Magn., R. turfacea (Wah-
lenb.) Körb. were reported for the Verkhnekolymskoe Highland (Kotlov, 1991, 1993a,
1993b, 1995, 2004). Finally, Sheard et al. (2017) reported R. freyi H. Magn., R. roscida
(Sommerf.) Arnold, and R. septentrionalis Malme. In total, ten species of the genus
Rinodina were known for the Magadan Region before the present study.
The Magadan Region, with an area of 461400 km2, lies in the northeastern part
of the Russian Far East. The mountainous area framing the northern shores of the
Okhotsk Sea and the basin of the upper reaches of the Kolyma River is formed by the
ridges of the Kolyma Highlands and the spurs of the Chersky Ridge mountain sys-
tem. A narrow strip along the northern coast of the Okhotsk Sea is characterized by
a temperate continental climate with relatively low winter minimum temperatures
and variable weather conditions. The Okhotsk-Kolyma watershed is a climate bor-
der with very frosty winters, an average January temperature there is below –32°C
(Klyukin, 1970). The mountainous regions in the upper Kolyma River basin are
characterized by the greater climate continentality. According to the geobotanical
zoning by Reut (1970), different parts of the study area belong to the mountainous
area of dwarf pine-larch-birch forests of the Okhotsk coast, to the bog-tussock-tund-
ra region of the Yamsk-Tauy depression, to the area of mountain-arctic tundra, and
to the lichen woodlands of the Kolyma Highlands. Yurtsev (1974) assigns this ter-

ritory to the North Okhotsk province of the East Siberian subregion of the Boreal
floristic region.
The aim of our study is to contribute to the knowledge about the diversity of Rinodi-
na species in the Magadan Region, as well as about their ecology and distribution.
Material and Methods
The material was collected by the authors in 2011–2015 in several districts of the
Magadan Region (Olsky, Omsukchansky, Yagodninsky, Severo-Evensky, Tenkinsky,
and Khasynsky) (Fig. 1). Additionally, we studied vouchers from the herbaria of the
Institute of Biological Problems of the North, Far Eastern Branch of the Russian Aca-
demy of Sciences (MAG) and Komarov Botanical Institute of the Russian Academy
of Sciences (LE) in Russia, and the National Museum of Nature and Science (TNS) in
Japan. The lichens sampled in 2012–2013 are kept at the Federal Research Center for
Biodiversity of the Far Eastern Branch of the Russian Academy of Sciences (VLA).
Atotal of 40 samples from the Magadan Region were studied.
The morphological and anatomical features of the specimens were examined by
standard methods of light microscopy. Chromatography was not necessary because all
the studied species can be easily distinguished by anatomy and morphology as well as
by standard spot tests with KOH (K), Ca(ClO)2 (C), and C6H4(NH2)2 (P). The pre-
sence of sphaerophorin crystals was studied by the method of fluorescence in longwave
UV.
Results and Discussion
In total, 15 species of Rinodina were identified, of which R. cinereovirens Vain.,
R.endospora Sheard, R. laevigata (Ach.) Malme, R. metaboliza Vain., R. olivaceobrun-
nea C. W. Dodge et G. E. Baker, R. parasitica H. Mayrhofer et Poelt, and R. subpa-
rieta (Nyl.) Zahlbr. are new for the Magadan Region. Two species, R. endospora and
R.sicula H. Mayrh. et Poelt, are rare in Russia and have only recently been found
in North-eastern Asia (Sheard et al., 2017; Galanina et al., 2021). Rinodina archaea,
R.exi gua, R. milvina, and R. mniaroea were previously reported from the Magadan
Region (Korolev, Tolpysheva, 1980; Kotlov, 1995), but were not found during our field
stu dies, as well as in the herbarium collections. The presence of R. archaea and R.exi-
gua in the Far East of Russia has also not yet been confirmed (Sheard et al., 2017,
Galanina, Ezhkin, 2019; Galanina et al., 2021).
Newly recorded species for the Magadan Region
Rinodina cinereovirens Vain. (Plate I: 1, 2)
Rinodina cinereovirens is characterized by thin light gray or brownish gray thal-
lus without vegetative propagules (Plate I: 1). Apothecia quickly become narrow-
ly attached, sometimes almost stipitate (to 0.6–1.0 mm) with disc black and plane.
Thalline margin is entire and typically persistent (80–120 μm wide), with cortex ex-
panded to 20–60 μm wide. Rinodina cinereovirens has Physcia-type spores of Type A

develop ment, (21.5)23.0–25.5(27.5) × (10.0)11.5–13.5(14.0) μm (Plate I: 2). Torus
well developed. Crystals absent in cortex and present in medulla (sphaerophorin).
Spot tests all negative, the secondary metabolite sphaerophorin in longwave UV turns
blue-white.
Rinodina cinereovirens is closely related to R. turfacea but differs by more broadly
ellipsoid spores with more bluntly rounded apices. Furthermore, R. cinereovirens in-
habits bark and wood, in contrast to R. turfacea which typically grows on decaying
ground vegetation, less often on wood in oroarctic environments in North America
(Sheard et al., 2017).

Distribution. In Russia, the species has previously been reported as Rinodina tur-
facea var. cinereovirens (Vain.) H. Mayrhofer and as R. turfacea var. ecrustacea (Vain.)
H. Oliv. for different regions from the Leningrad Region to the Kamchatka Territo-
ry (Urbanavichene, Urbanavichus, 1998; Kotlov, 2008; Himelbrant et al., 2009; Spi-
sok…, 2010; Chesnokov, Konoreva, 2015; Sheard et al., 2017). Rinodina cinereovirens
is known in Europe from Scandinavia (Norway, Sweden, and Finland) (Mayrhofer,
Moberg, 2002). In North America the species was reported from Newfoundland, New
Brunswick, Wapusk National Park, northern Manitoba, northern Ontario, and Alaska
(Sheard, 2018).
Ecology. Rinodina cinereovirens was found on bark of Alnus sp., Betula sp., Cho-
senia arbutifolia, and Larix sp. in floodplain shrub communities and coniferous forests.
Specimens examined: Olsky District, Tauy River, the Niro station, floodplain terrace,
59°4717.2N, 148°1613.2E, 36 m a. s. l., old larch forest with birch and alder, with tall grass and

twigs of Larix sp., 9 VIII 2012, Yakovchenko 25-12, VLA.
Rinodina endospora Sheard (Plate I: 3, 4)
The detailed description was given by Sheard (2010), Sheard et al. (2017), and
Galanina et al. (2021). The species is characterized by a gray to gray-brown verrucose
or areolate thallus, narrowly attached apothecia with flakes of the epinecral layer on
the thallus, large Dirinaria-type spores (20.5)22.0–24.0(27.5) × (8.5)9.0–10.0(11.0)
μm, often asynchronous and of Type B development (Plate I: 3, 4). Rinodina endospora
can be confused with R. metaboliza which also has Dirinaria-type spores, but they are
of smaller size (13.5)17.5–19.0(23.0) × (8.5)9.0–10.0(11.0) μm (Sheard, 2010).
Distribution. This is the third location of this species in Russia and Northeas-
tern Asia. Previously, the species was reported from Kamchatka (Ust’-Bol’sheretsky
District, on bark of Chosenia arbutifolia) (Sheard et al., 2017) and from Sakhalin
Island where it was found on bark of Populus sp. in riparian forest (Galanina et al.,
2021). Rinodina endospora was previously considered to be a western North American
endemic species distributed in California along the coastal ranges and in the Sierra
Nevada (Sheard, 2010). This study suggests it is the western North American ― East
Asian species with disjunct distribution.
Ecology. The species was found on bark of Chosenia arbutifolia in the valley forest.
Specimen examined: Olsky District, Magadansky Reserve, Kava-Chelomdzhinsky area,
Chelomd zha River valley, 59°4750.3N, 148°1252.9E, 36 m a. s. l., floodplain forest, on bark of
Chosenia arbutifolia, 12 VII 2012, Zheludeva, MAG О-4583.

Rinodina laevigata (Ach.) Malme (Plate II: 1, 2)
Rinodina laevigata is characterized by Physcia-Physconia-type spores (14.5)18.5–
19.5(22.5) × (7.0)8.5–9.0(10.5) μm of Type A development, thin poorly developed
thallus, and usually thick lower apothecial cortex (Plate II: 1, 2). Rinodina laeviga-
ta can be confused with R. sibirica H. Magn. but differs by a less developed thallus,
grayish color, smaller spores, and more rounded and less elongated lumina. Apothecia
in R. laevigata are broadly attached to the thallus, with typical plane discs and thick
lower apothecial cortex.
Distribution. In Russia, the species is known from the North Caucasus to Wes-
tern Siberia (Kotlov, 2008), but most probably is understudied. Rinodina laevigata
is widespread and known from Norway, Sweden, Finland, and Scotland in Europe
(Mayr hofer, Moberg, 2002), also from Alaska to California and in the Sierra Nevada in
the western part of North America (Sheard, 2010).
Ecology. Rinodina laevigata was collected on bark of Pinus pumila (Pall.) Regel
and Larix sp.
Specimens examined: Khasynsky District, ca. 25 km SW of Atka, 60°3722.7N, 151°3331.6E,
1110 m a. s. l., on twig of Larix sp., 11 VIII 2012, Ohmura 10172B, Yakovchenko, Zheludeva, TNS; Ten-
kinsky District, Matrosov mine, thickets of dwarf pine, 61°3828N, 147°4810E, on bark of Pinus
pumila, 8 VI 2015, Pavlov, VLA.
Rinodina metaboliza Vain. (Plate II: 3, 4)
Rinodina metaboliza is characterized by a Dirinaria-type spores (13.5)17.5–
19.0(23.0) × (8.5)9.0–10.0(11.0) μm of Type B development (Plate II: 4). The species
is very variable in thallus morphology, spore size and apothecial convexity (PlateII:3).
Rinodina metaboliza can be confused with R. endospora. For the differences, see the de-
scription of R. endospora above.
Distribution. The species was described by Vainio (1928) from several places
along the Yenisei River in Siberia. In Russia, it is known from the republics of Karelia
and Komi, and South Siberia (Eastern Sayan Mountains) (Kotlov, 2008; Urbanavi-
chene, Urbanavichus, 2009). In Europe, the species was found in Scandinavia (central
Sweden and Norway) (Mayrhofer, Moberg, 2002). In North America, it is a western
species extending from coastal Alaska to southern California and inland to the Rocky
Mountains (Sheard, 2010).
Ecology. Rinodina metaboliza was collected on bark of Populus sp. in floodplain forest.
Specimen examined: Olsky District, Magadansky Reserve, Chelomdzha River, 59°4750.3N,
148°1252.9E, 36 m a. s. l., floodplain forest with Chosenia arbutifolia and Alnus sp., on bark of Po-
pulus sp., 12 VII 2012, Zheludeva, MAG О-4584.
Rinodina olivaceobrunnea C. W. Dodge et G. E. Baker (Plate II: 5, 6)
Rinodina olivaceobrunnea is characterized by Physcia-type spores (16.5)20.5–
21.5(26.0) × (8.0)9.5–10.0(12.0) μm of Type A development (Plate II: 6). The species

103
Galanina et al. The genus Rinodina in the Magadan Region (Far East of Russia)
104
has abundant and small, narrowly attached apothecia (Plate II: 5). Rinodina olivaceo-
brunnea can be confused with R. turfacea, but differs in smaller spores and apothecia,
absence of a massive columnar lower cortex, and lack of sphaerophorin. R.olivaceo-
brunnea can also be confused with R. archaea, but it is distinguished by its Physcia-type
spores, thick lower cortex, and typically muscicolous rather than lignicolous habitat
(Sheard, 2010).
Distribution. In Russia, R. olivaceobrunnea has wide distribution and was pre-
viously found in the Arctic (Novaya Zemlya, Taimyr, and Chukotka), Murmansk Re-
gion, Komi Republic, North Caucasus (Karachayevo-Circassian Republic), and West
Siberia (Kotlov, 2008). Rinodina olivaceobrunnea is distributed in both hemi spheres
being known in Europe, central Africa, Australasia, Antarctica, and North America
(Mayrhofer, Moberg, 2002; Sheard, 2010).
Ecology. Rinodina olivaceobrunnea was collected on old wood near the airport.
Specimen examined: Severo-Evensky District, Evensk village, 61°5502.8N, 159°1420.8E, 3 m
a. s. l., old vegetable gardens behind the airport, on old logs (wood), 11 VII 2015, Zheludeva, MAG
СЭ-4585.
Rinodina parasitica H. Mayrhofer et Poelt (Plate III: 1, 2)
Rinodina parasitica is characterized by a lichenicolous habit and brown thallus,
Physcia-Physconia-type spores (13.5)16.0–16.5(19.0) × (7.0)8.5–9.0(10.5) μm of
Type A development (Plate III: 1, 2). It can be confused with R. obnascens (Nyl.) Oliv.,
another lichenicolous species, but the latter has Milvina-type spores and gray thallus
with minute dark brown to black consoredia (Sheard, 2010). R. obnascens has not been
found in Russia yet.
Distribution. In Russia, R. parasitica was found in Siberia (Krasnoyarsk Ter-
ritory, Baikal Region) (Kotlov, 2008). The species occurs in scattered localities in
Europe (Norway, Sweden, and Finland) (Mayrhofer, Moberg, 2002), Asia (Mongolia)
(Byazrov, 2013), and North America, where it is known in Alaska and western Canada,
southern Rocky Mountains, coastal ranges, and Sierra Nevada (Sheard, 2010).
Ecology. Rinodina parasitica was found on the thallus of an unidentified Aspi-
cilia. It is arctic-alpine lichen growing on species of Aspicilia and Rhizocarpon (Kot-
lov,2008).
Specimen examined: Olsky District, Magadansky Reserve, Yamsky area, Studenaya station, a
small mountain, 59°4538.0N, 153°3424.9E, 69 m a. s. l., on Aspicilia sp. growing on rock, 15 VII
2015, Zheludeva, MAG О-4586.

Rinodina subparieta (Nyl.) Zahlbr. (Fig. 2)
Rinodina subparieta is characterized by a Physconia-type spores (15.0)18.5–
19.5(23.0) × (8.5)10.0–11.0(13.0) μm of Type A development, light gray scattered
areoles, producing atranorin (K+ yellow) and whitish soredia forming along the areole
margins in a labriform soralia (Fig. 2). Rinodina subparieta are similar to R. willeyii
Sheard et Giralt, but the latter has Pachysporaria-type spores, whitish areolate thallus
(than subsquamulose), and producing pannarin (P+ cinnabar).
Dist rib uti on. In Russia, it is a widespread species known from the Caucasus to the
Far East (Spisok…, 2010; Himelbrant, Stepanchikova, 2011; Galanina, 2013; Sheard et
al., 2017). In Europe it is known from Scotland (Giavarini et al., 2009), Scandinavia and
Aust ria (Tonsberg, 1992; Mayrhofer, Moberg, 2002). Rinodina subparieta is also known
from Mongolia (Hauck, Javkhlan, 2006) and eastern Asia with a distribution spanning
Russia, Japan, and Korea (Sheard et al., 2017). In North America, R. subparieta has a Pa-
cific and North Atlantic disjunct distribution (Sheard, 2010; Resl et al., 2016).
Ecology. Rinodina subparieta was collected on bark of Alnus sp. in old larch forest.
In Russia, the species was found on coniferous and deciduous trees (Abies sp., Alnus
sp., Betula sp., Castanea sp., Chosenia arbutifolia, Picea sp., Prunus sp., Quercus sp.,
Salix sp., and Taxus sp.) in deciduous and mixed forests, often along river valleys. It
occurs from the sea level to 2550 m (Sheard et al., 2017).
Specimen examined: Olsky District, Tauy River, the Niro station, floodplain terrace, 59°4717.2N,
148°1613.2E, 36 m a. s. l., old larch forest with Betula sp., Alnus sp., tall grasses and shrubs, on bark
of Alnus sp., 6 VIII 2011, Zheludeva, MAG О-4587.

Species previously known from the Magadan Region
Rinodina freyi H. Magn. (Plate I: 5, 6)
Rinodina freyi is characterized by gray-green continuous thallus, apothecia fre-
quently becoming contiguous on small thalli (Plate I: 5), and relatively small, darkly
pigmented Physcia-type spores (12.0)15.0–16.0(18.5) × (6.0)7.5–8.0(9.0) μm of Type
A development with a heavy torus (Plate I: 6). Rinodina freyi can be confused with
R. septentrionalis, but the latter species has copper-brown thallus consisting of small
discrete verrucae, narrowly attached and scattered apothecia.
Distribution. In Russia, R. freyi was previously recorded from the Magadan
Region, Kamchatka Territory, Sakhalin Island, Khabarovsk and Primorye territo-
ries (Sheard et al., 2017; Galanina et al., 2021). It has also been reported from Japan
(Sheard et al., 2017) and western Mongolia (Hauck et al., 2013). European distribu-
tion of this species is poorly known although originally it was described from Europe
(Switzerland) (Magnusson, 1947); the species is also published from Germany (Wirth
et al., 2013). Sheard (2010) indicated that R. freyi is closely related to the European
R.septentrionalis (Giralt, Mayrhofer, 1995). Rinodina freyi is the most common spe-
cies of the genus in North America, being frequent in both the east and west of the
continent (Sheard, 2010).
Ecology. In the Magadan Region, R. freyi was found on bark of Alnus, Chosenia,
and Salix in floodplain Chosenia forest and alder forest. In North America it inhabits
various tree species, including Abies spp., Acer spp., Alnus crispa (Aiton) Pursh, Betula

Rinodina milvina (Wahlenb.) Th. Fr.
Rinodina milvina is characterized by thick dark brown thallus and Milvina-type
spores (15.5)18.0–19.0(22.0) × (7.5)9.5–10.5(12.0) μm of Type A development. Young
thalli of R. milvina can be confused with R. parasitica, which is well distinguished by
its smaller Physcia- Physconia-type spores.
Distribution. Rinodina milvina was previously noted in the Magadan Region by
Kotlov (1995). In Russia, the species is widespread from the European part to the Far

107
East, and from the Southern Siberia to the Arctic (Novaya Zemlya) (Kotlov, 2008).
Rinodina milvina has scattered distribution in Europe (Mayrhofer, Moberg, 2002) and
also occurs in Asia (Turkey, Iraq, Georgia, Armenia, Azerbaijan, Kazakhstan, Mongo-
lia, and Japan) (Wagner, Spribille, 2005; Kotlov, 2008; Byazrov, 2010; Ohmura, Kashi-
wadani, 2018), North Africa (Kotlov, 2008), and North America (Greenland, Rocky
Mountains, Sierra Nevada, Cascades and costal range) (Sheard, 2010).
Ecology. Rinodina milvina inhabits siliceous rocks, sometimes parasitizing crus-
tose lichens (Mayrhofer, Moberg, 2002; Kotlov, 2008). In North America, the species
was found on granites, quartzites and other acidic rocks, on sandstone, volcanic rocks,
from 900 to 3660 m a. s. l. (Sheard, 2010).
Rinodina mniaroea (Ach.) Körb.
Rinodina mniaroea is characterized by its apothecia becoming convex and thal-
line margin becoming excluded, large Physcia-type spores (20.5)24.5–25.5(30.0) ×
(9.5)11.5–12.5(14.5) μm of Type A development. Rinodina mniaroea is similar to
R.turfacea, which differs by producing sphaerophorin (UV+ blue-white) and persis-
tently plane apothecial discs with prominent thalline margins. Another species to be
distinguished from R. turfacea is R. olivaceobrunnea, which differs by its smaller apo-
thecia and spores.
Distribution. Rinodina mniaroea was previously reported from the Magadan
Region by Kotlov (1995). In Russia, the species is widespread in the northern and
mountain regions (Arctic, northern European part, North Caucasus, Siberia, Urals,
Altai, Far East) (Makarova, Katenin, 1983, 1992; Sedelnikova, 1990; Kotlov, 2008).
In Europe it occurs in central part (Wirth, 1995; Giavarini et al., 2009), Iberian Penin-
sula (Giralt, 2010), and Scandinavia (Mayrhofer, Moberg, 2002). In Asia R. mniaroea
was reported from the Caucasus, Himalayas, Mongolia, and China (Vezda, 1965; Kot-
lov, 2008). In North America, R. mniaroea is common in the western Arctic, the Rocky
Mountains and scattered in the eastern Arctic and Greenland (Sheard, 2010).
Ecology. Rinodina mniaroea grows on mosses and plant debris in the arctic-alpine,
less often in the subalpine and boreal zones (Mayrhofer, Moberg, 2002; Kotlov, 2008).
In North America it was recorded up to 4070 m a. s. l. in Arizona (Sheard, 2010).
Rinodina roscida (Sommerf.) Arnold
Rinodina roscida is characterized by large Physcia-type spores (22.5)30.0–
32.0(39.5) × (10.5)12.5–13.5(16.0) μm and Type A or rarely B development. R. ros cida
can be confused with R. turfacea and differs in its light gray thallus lacking sphaero-
phorin, pruinose apothecial discs, J+ blue lower cortex of apothecial margins, signifi-
cantly larger spores with often submucronate apices (Sheard, 2010).
Distribution. Rinodina roscida is widespread in the northern and mountainous
regions of Northern Hemisphere (Mayrhofer, Moberg, 2002; Wirth et al., 2013): in the
Arctic from Scandinavia to Chukotka and southbound to Southern Siberia (Trans-Bai-

kal Territory, Sayany) and Asia (Caucasus, Himalayas, Mongolia, China) (Mayrhofer,
Moberg, 2002; Kotlov, 2008; Spisok…, 2010). In North America it is common in the
Arctic, especially in the west, extending southwards in the Rocky Mountains (Sheard,
2010).
Ecology. Rinodina roscida was collected on mosses and plant debris on rock in
mountains.
Specimens examined: Omsukchansky District, 500 km NE from Magadan, foothill of Kilganskie
Range, vicinity of Dzhuletta mining camp, 61°1139.8N, 153°5849.8E, 1480 m a. s. l., upper part

Rinodina septentrionalis Malme
= Rinodina hyperborea H. Magn.
Rinodina septentrionalis is characterized by Physcia-type spores (13.5)16.0–
17.0(19.5) × (6.5)7.5–8.5(9.5) μm with well-developed torus and Type A develop-
ment. Rinodina septentrionalis has copper-brown thallus consisting of small discrete
verrucae, narrowly attached and scattered apothecia. For the differences from similar
R. freyi see its description.
Distribution. Rinodina septentrionalis was previously reported for the Magadan
Region by Kotlov (1995) as R. hyperborea. In Eurasia, R. septentrionalis is widely dis-
tributed in the Arctic and boreal zones and in mountainous regions from northern
Scandinavia to Kamchatka Peninsula and southbound to Georgia, Kazakhstan, Altai
Mts, Sikhote-Alin Mts, Japan (Insarov, Pchelkin, 1984; Davydov, 2001; Giralt, 2001,
2010; Mayrhofer, Moberg, 2002; Tschabanenko, 2002; Kotlov, 2008; Himelbrant et

2013; Chesnokov, Konoreva, 2015; Sheard et al., 2017; Galanina et al., 2021). In North
America it is common in the Arctic, extending southwards in the Rocky Mountains to
Colorado (Sheard, 2010).
Ecology. Rinodina septentrionalis was collected from the bark of Alnus sp., Larix
sp., and Salix sp. In the Altai Mts, it was found on the bark of deciduous and coniferous
trees in the wet habitats of the forest belt (Davydov, 2001). In North America it was
recorded up to 3050 m a. s. l. in the Rocky Mountains (Sheard, 2010).

Rinodina sibirica H. Magn. (Plate III: 3, 4)
Rinodina sibirica is characterized by Physcia-Physconia-type spores (17.0)20.0–
21.5(25.5) × (8.5)10.0–11.5(13.0) μm with the well-developed torus, the dark-colo-
red cell walls, and Type A development (Plate III: 4). Rinodina sibirica has erumpent
apothecia broadly attached at first and then becoming narrow at the base, scattered,
numerous with the dark brown to black disk becoming convex, sometimes hemisphe-
rical (Plate III: 3). Rinodina sibirica can be often confused with R. archaea, but the
latter species has Physconia-type spores and mainly lignicolous (Sheard, 2010). The
young apothecia of R. sibirica with plane discs can be confused with such of R. cinere-
ovirens, but the latter has large Physcia-type spores and crystals in medulla (sphaero-
phorin, UV+ blue-white). Specimens of R. sibirica can be often referred to R. sophodes,
which differs by small Milvina-type spores and European distribution (Sheard, 2010).
Rinodina sophodes was probably erroneously reported for the Far East of Russia.
Distribution. Rinodina sibirica was previously reported for the Magadan Region
by Kotlov (1995). Rinodina sibirica is an American-Asian species with a wide amphi-
beringian range (Galanina et al., 2021). The species was described from the environs of
Yeniseisk, Tomsk, and Tobolsk in Russia (Magnusson, 1936). Later, it was additionally
reported from numerous places in Siberia along the rivers Yenisei, Ob, Irkut, Lena, and
Aldan (Magnusson, 1947), as well as from Altai and Sayan (Kotlov, 2008), and from
Mongolia (Golubkova, 1981). Recently R. sibirica was reported from the Trans-Baikal
and Khabarovsk territories, the Magadan Region, Sakhalin Island, and the Kamchat-
ka Peninsula (Sheard et al., 2017; Galanina et al., 2021). The species was also reported
from North America (Thomson, 1997, as R. granulans Vain.; Sheard, 2010).
Ecology. Rinodina sibirica was collected on bark of Betula sp., Larix sp., and Salix
sp. The species grows mainly on bark of deciduous trees (e. g. Alnus spp., Betula spp.,
Padus avium Mill., Populus spp., Salix spp., Sorbus sp.), less often on conifers (Abies
sp., Larix sp., Picea sp., Pinus sp.) and on wood (Magnusson, 1936, 1947; Kotlov, 2008;
Sheard, 2010; Sheard et al., 2017).
Specimens examined: Olsky District, floodplain of Kava River, Bogot Island, 59°4616.6N,
147°5926.7E, 39 m a. s. l., larch-birch forest, on bark of Betula sp., 7 VII 2012, Zheludeva, MAG

(Plate III: 6) of Type A development, and the presence of gyrophoric acid in the apoth-
ecial margin (C+ red).
Distribution. Rinodina sicula is described from Italy (Mayrhofer, Poelt, 1979). It
is known in Europe from Italy, Iberian Peninsula, Denmark, Sweden (Mayrhofer, Poelt,
1979; Giralt, Llimona, 1997; Mayrhofer, Moberg, 2002; Mayrhofer, Sheard, 2007) and
in Northeastern Asia from Kamchatka Peninsula, Magadan Region, Trans-Baikal Ter-
ritory (Sheard et al., 2017).
Ecology. Rinodina sicula is a saxicolous species. In the Magadan Region it was
found on rocks in the middle part of the slope with cliffs.
Specimen examined: Omsukchansky District, 500 km NE to Magadan, foothill of Kilganskie
Range, vicinity of Dzhuletta mining camp, 61°1143.3N, 153°5834.9E, 1321 m a. s. l., middle part of
the slope with cliffs, on rocks, 9 VIII 2012, Yakovchenko M-12-27-4, VLA; ibid., Yakovchenko M-12-
27-1, VLA (Sheard et al., 2017).
Rinodina turfacea (Wahlenb.) Körb.
Rinodina turfacea is characterized by brownish-gray thallus, large apothecia with
concave or plane disc, persistent thalline margin containing crystals of sphaeropho-
rin, Physcia-type spores (22.0)27.5–29.5(35.0) × (10.5)12.5–13.5(15.5) μm of Type A
development (Shaerd, 2010). Rinodina turfacea can be confused with R. cinereovirens;
for the differences, see the description of R. cinereovirens.
Distribution. Rinodina turfacea was previously reported from the Magadan
Region by Kotlov (1995). It is mainly northern circumpolar species restricted to the
Arctic and Subarctic territories in Eurasia from Scandinavia to the Kamchatka Pen-
insula with southernmost locations in the Mongolian and Chinese parts of the Altai
(Schubert, Klement, 1971; Afonina et al., 1980; Makarova, Katenin, 1983; Makryi,
1986; Sedelnikova, 1990; Abbas et al., 2001; Davydov, 2001; Mayrhofer, Moberg, 2002;
Tschabanenko, 2002; Kotlov, 2008; Himelbrant et al., 2009; Skirina, 2012; Wirth et al.,
2013; Sheard et al., 2017; Galanina et al., 2021). In North America, it is common in
the Arctic, southward to the Rocky Mountains in Montana and Wyoming, also in the
state of Colorado (Sheard, 2010).
Ecology. Rinodina turfacea was found on plant debris.
Specimens examined: Olsky District, Kamenny Range, vicinity of the Magtur tourist base, flood-
plain of Pyany stream, 59°4524.5N, 149°3917.9E, 9 m a. s. l., floodplain shrubs with Alnus sp.,
on plant debris, 6 VIII 2013, Galanina М-13-178-3, VLA; ibid., Atargan Peninsula, 59°3235.6N,
151°2927.2E, 3 m a. s. l., seashore, on dry pebble on plant debris, 3 VIII 2016, Zheludeva, MAG
О-4595; Omsukchansky District, 500 km NW from Magadan, foothill of Kilganskie Range, vicinity
of Dzhuletta mining camp, 61°11’43.3’’N, 153°58’34.9’’E, 1321 m a. s. l., middle part of the slope with
cliffs, on plant debris, 9 VIII 2012, Zheludeva, MAG; ibid., on plant debris, Yakovchenko 27-12-2, 27-
12-3, VLA (Sheard et al., 2017); ibid., on plant debris, 11 VIII 2012, Ohmura 10145B, TNS.
As a result of the study, the list of Rinodina known from the Magadan Region con-
sists of 15 species, 7 of which are reported for the first time for the region (R. cinereo-
virens, R. endospora, R. laevigata, R. metaboliza, R. olivaceobrunnea, R parasitica, and
Galanina et al. The genus Rinodina in the Magadan Region (Far East of Russia)
112
R. subparieta). The genus is mainly represented by species typically occurring in the
northern regions (R. cinereovirens, R. metaboliza, R. mniaroea, R. olivaceobrunnea,
R.roscida, R. septentrionalis, and R. turfacea).
Despite the new data, the Rinodina genus in the Magadan Region requires further
study. Noteworthy are the species R. endospora and R. sicula which are rare in Russia
and have only recently been found in Northeastern Asia (Sheard et al., 2017; Galanina
et al., 2021). These species might be rarely reported because saxicolous Rinodina spp.
are poorly investigated in general. It can be assumed that they occur more frequently
in the northern regions of Eurasia within epilithic lichen communities. Other species
requiring attention are R. laevigata and R. sibirica which are probably widespread in
Russia, although rarely found in some regions. The distribution of both taxa is worthy
of further research.

Rinodina salicis Lee & Hur and Rinodina zeorina Lee & Hur are described as new lichen-forming fungi from forested wetlands or a humid forest in South Korea. Rinodina salicis is distinguishable from Rinodina excrescens Vain., the most similar species, by its olive-gray thallus with smaller areoles without having blastidia, contiguous apothecia, non-pruinose discs, paler disc color, wider ascospores in the Pachysporaria -type II, and the absence of secondary metabolites. Rinodina zeorina differs from Rinodina hypobadia Sheard by areolate and brownish thallus, non-pruinose apothecia, colorless and wider parathecium, narrower paraphyses with non-pigmented and unswollen tips, longer and narrower ascospores with angular to globose lumina, and the absence of pannarin. Molecular analyses employing internal transcribed spacer (ITS) sequences strongly support the two new species to be unique in the genus Rinodina . An updated key is provided to assist in the identification of all 63 taxa in Rinodina of the far eastern Asia.
... Mountain-ash was not among the phorophytes of North American specimens of R. subminuta examined by Sheard (2010). However, it occurs on mountain-ash in Japan and Russia (Sheard et al. 2017;Galanina et al. 2021b). The occurrence in New Brunswick is from an elevation higher than that of the local topoclimatic limit of Sugar Maple. ...
... The North American and global distributions of R. subpariata (including R. degeliana) are broadly similar to those of R. efflorescens (Sheard 1995(Sheard , 2010Lendemer et al. 2014;Sheard et al. 2017;Galanina et al. 2021b). In eastern North America, it occurs extensively in the Appalachian-Great Lakes-Maritimes region and was recently reported from Newfoundland (Sheard 2018). ...

Fifteen species of the crustose lichen genus Rinodina are confirmed in New Brunswick, Canada. We report four corticolous species, Rinodina pachysperma, Rinodina populicola, Rinodina septentrionalis, and Rinodina tenuis, and the saxicolous Rinodina tephraspis in the province for the first time. A previous report of Rinodina granuligera is based on a specimen that we have re-identified as Rinodina cinereovirens. We note distinguishing characteristics, habitats, substrata, relative abundance, and biogeographic relationships of each species and provide an identification key and distribution maps. The most frequently occupied phorophytes (tree substrata) are Sugar Maple (Acer saccharum), Yellow Birch (Betula alleghaniensis), and Eastern White Cedar (Thuja occidentalis). Some species are closely associated with particular habitats, phorophytes, or both. For example, we found R. pachysperma only in floodplain forests dominated by Silver Maple (Acer saccharinum), and R. tenuis only on Eastern White Cedar in wet cedar-dominated stands. In contrast, we recorded Rinodina freyi on numerous phorophyte species in a relatively wide range of habitats. Other than Eastern White Cedar and Balsam Fir (Abies balsamea), conifers are rarely colonized by Rinodina species in New Brunswick. Most Rinodina species are probably not currently of conservation concern in the province. However, R. cinereovirens is known from only two collections, one dating from 1902. The other, from 2007, was on Black Ash (Fraxinus nigra) in a swamp forest next to an active peat-mining operation. The expected devastation of ash species by the invasive Emerald Ash-borer (Agrilus planipennis) is a further threat to this occurrence and to any lichens for which ash may be an important phorophyte.

The presented work is based on the study of material collected by F.A. Romanyuk in the surroundings of Sarychev Peak active volcano on Matua Island, middle Kurils in 2017. Two families – Physciaceae and Caliciaceae – were sorted out from the collection and studied at first. As a result, seven species of the families were found: two species of the genus Rinodina, two species of the genus Physcia, two species of the genus Buellia and the species Tetramelas chloroleucus. All found species of the studied families were first identified for Matua Island. Matua Island is the northernmost location point in Eurasia for the species Rinodina ascociscana. Buellia badia is a new registered species for the Sakhalin Region.

The presented work is based on the study of extensive material that authors collected in 2002–2008 in Primorye Territory (Khasanskiy and Ussuriyskiy districts). The study resulted in the first record of Rinodina albertana in mainland Eurasia. R. albertana is a rare species for Russia and Eurasia and just recently has been found in Northeast Asia. This is the second finding of this species in Russia and Northeastern Asia. Previous record of the species was on Sakhalin Island (Nevelskiy District) on bark of Populus sp. in a valley forest. The species was previously described from Canada, and also found in the USA. Before our discovery the species was considered endemic for North America. This study suggests it is the East Asian ― North American species with disjunct distribution. Rinodina albertana is well distinguished by its large Dirinaria-type spores and the presence of blastidia or РЕДКИЕ ВИДЫ 76 marginal consoredia among all species found in Northeast Asia. Rinodina oleae is similar to R.albertana by its Dirinaria-type spores, but it has smaller spores (12.0) 15.0–16.5 (19.0)μm, and does not have blastidia or consoredia. In addition, thickenings of the spore septumof R. oleae are very difficult to see, whereas in R. albertana thickenings of the spore septumare perfectly distinguishable. The work also presents a brief description of the rare species R.albertana found in Primorye Territory.

The presented work is based on the study of extensive material collected by Ezhkin A. K. in 2014–2018 from the islands of Kunashir, Iturup, Paramushir, and Shikotan. As a result of the study, the new list of species of the genus Rinodina for the Kuril Islands consists of 17 taxa. One species, Rinodina herrei H. Magn., is new to northeastern Asia and Russia, 14 taxa are new to the Kuril Islands. The genus Rinodina is represented by species with disjunctive distribution by 35.3 % (6 species). They are divided into two groups: East Asian – West American (R. herrei, R. megistospora) and East Asian – East North American (R. ascociscana, R. subminuta, R. tenuis and R. willeyi). East Asian species account for 17.6 % (3 species: R. hypobadia, R. subalbida and R. xanthophaea) of the known number of Rinodina species of the Kuril Islands.

The paper presents new data on distribution of the lichen Rinodina megistospora in the Russian Far East and its revealed range in eastern Asia. R. megistospora is recorded for the first time for the Sakhalin Region (Sakhalin and Iturup islands). It has been found on the territory of Russia in eight localities in the boreal and nemoral zones of Northeast Asia. The species grows in old-growth intact coniferous and oak forests on bark of Betula sp., Kalopanax septemlobus, Picea sp., Quercus crispula and Sorbus sp. Current data suggest that R. megistospora is one of the species belonging to the Eastern Asiatic — Western North American group of species, characterized by disjunctive range. The paper presents the anatomical and morphological description of Rinodina megistospora, based on the examined specimens.

The placement of all fungal genera is provided at the class-, order- and family-level. The described number of species per genus is also given. Notes are provided of taxa for which recent changes or disagreements have been presented. Fungus-like taxa that were traditionally treated as fungi are also incorporated in this outline (i.e. Eumycetozoa, Dictyosteliomycetes, Ceratiomyxomycetes and Myxomycetes). Four new taxa are introduced: Amblyosporida ord. nov. Neopereziida ord. nov. and Ovavesiculida ord. nov. in Rozellomycota, and Protosporangiaceae fam. nov. in Dictyosteliomycetes. Two different classifications (in outline section and in discussion) are provided for Glomeromycota and Leotiomycetes based on recent studies. The phylogenetic reconstruction of a four-gene dataset (18S and 28S rRNA, RPB1, RPB2) of 433 taxa is presented, including all currently described orders of fungi.
