Abstract. The first lichenological inventory in Koryakia has resulted in the list of 315 species reported from Parapolsky Dale, within and in vicinities of the Koryak State Reserve. Altogether 46 species are published from the Kamchatka Territory for the first time, including Lecanographa grumulosa new to Russia, East Asia and Beringia; Cercidospora trypetheliza, Lecania dubitans, Per-tusaria borealis, Piccolia ochrophora, Protoparmelia cupreobadia, Rimularia badioatra and Stran-gospora moriformis new to Russian Far East; Abrothallus bertianus, Cladonia strepsilis, Physciella melanchra, Rimularia badioatra, Sclerococcum parasiticum, Sphinctrina leucopoda and Strangospora moriformis new to Beringia. The lichen diversity of the study area is relatively poor due to natural reasons. Comparison with neighboring regions (Kamchatka Peninsula, Chukotka, Magadan Region, Yakutia and Alaska) shows that the lichen flora of Parapolsky Dale contains almost no specific species. The majority of the species recorded here are also known from neighboring regions, especially Alaska and Kamchatka Peninsula.

Keywords: lichen flora, new records, Beringia, Kamchatka, Koryak State Reserve, Koryakia.

Резюме. Результатом первых лихенологических исследований в Корякии стал список из 315 видов, обнаруженных на территории Парапольского Дола, в границах и в окрестностях Корякского государственного заповедника. Всего 46 видов приведены впервые для Камчатского края, в том числе Lecanographa grumulosa — вид, новый для России, Восточной Азии и Берингийского экорегиона; Cercidospora trypetheliza, Lecania dubitans, Pertusaria borealis, Piccolia ochrophora, Protoparmelia cupreobadia, Rimularia badioatra и Strangospora moriformis —

виды, новые для Российского Дальнего Востока; Abrothallus bertianus, Cladonia, Physciella mel-anchra, Rimularia badioatra, Sclerococcum parasiticum, Sphinctrina leucopoda и Strangospora mori-formis — виды, новые для Берингии. Лихенофлора района исследований относительно бедна по естественным причинам. Сравнение с лихенофлорами ближайших регионов (полуостров Камчатка, Чукотка, Магаданская обл., Якутия и Аляска) показало, что лихенофлора Параполь-ского Дола практически не содержит каких-либо специфичных для нее видов. Подавляющее большинство выявленных видов известно с территории Аляски и полуостровной части Камчатки.

Introduction

The geographical affinities between the lichen diversities of the Pacific regions of Northern Asia and North America are clearly predictable due to well-known palaeo-geographical processes in the Beringian Ecoregion (see Brigham-Grette, 2004; Cook et al., 2005; Waltari et al., 2007; Krasnov et al., 2015) and long-distance transportation of diaspores, but still insufficiently investigated. One of the most important reasons is poor knowledge about lichen diversity of the Russian regions in North Pacific.

Koryakia is one of the last lichenologically fully unexplored large territories in Russia, as well as in Beringia.

Koryakia (formerly Koryak Autonomous Okrug, now part of Kamchatka Territory) occupies the northernmost part of the Kamchatka Peninsula and adjacent mainland area. The Koryak State Reserve is the only reserve in Koryakia; it consists of three separate parts: "Mys Govena" (S part of the Goven Peninsula), "Bukhta Lavrova" (Lavrova Bay), and "Parapolsky dol" (Parapolsky Dale). The total area of its terrestrial part is about 3188 km2 (Kronotsky..., 2018). The investigated part Parapolsky Dale (1764 km2) lies in the north-western part of Koryakia in a tectonic depression between the Penzhin-sky Range and Koryakskoe Highland (Fig. 1). Parapolsky Dale is biogeographically one of the key parts of Kamchatka and represents a natural landscape barrier against the mainland in the narrowest part of the peninsula. Numerous animals have here the limits of their ranges, including different insects (see Mutin, 2014), mammals like moose and other forest species. The main type of landscape of Parapolsky Dale is swampy lowland (elevation mainly from 50 to 100 m a. s. l.) with a dense river net and thousands of lakes of various sizes. The largest of them is Lake Talovskoe (44 km2) (Gusakov, 1998). Although Parapolsky Dale is situated within the hypoarctic zone, shrub communities composed of Pinuspumila (Pallas) Regel or Betula divaricata Ledeb. (= Betula middendorffii Trautv. et Mey.), or more rarely Alnus fruticosa Rupr. [= Duschekia fruticosa (Rupr.) Pouzar; Alnusalnobetula (Ehrh.) K. Koch subsp. fruticosa (Rupr.) Raus], are distributed only on slopes of the depression and small local hills. Same positions are also occupied by lichen- and moss-dwarf shrub tundras with Betula exilis Sukacz. [= Betula nana L. subsp. exilis (Sukaczev) Hulten], Empetrum nigrum L., Ledum decumbens (Ait.) Lodd. ex Steud. (= Rhododendron decumbens D. Don ex G. Don), Vaccinium uliginosum L., and V. vitis-idaea L. The most part of the lowland is covered by swamps with Eriophorum vaginatum L. and Carex spp., shores of swamps and lakes are overgrown by Salix spp. communities. Forest communities are represented only by floodplain forests with Salix arbutifolia Pall. [= Chosenia arbutifolia (Pall.) A. Skvorts.], Populus suaveolens Fisch., Salix schwerinii E. Wolf, and S. udensis Trautv. et Mey. along the banks of main rivers (Neshataeva et al, 2017). Special lichenological studies in Parapolsky Dale, as well as in the whole Koryakia, have not been conducted ever before.

Material and methods

The specimens were collected by Dmitry E. Himelbrant (abbreviated as DH) and Valentina Yu. Neshataeva in August 2016 in Parapolsky Dale (within the Koryak State Reserve and its vicinities), Penzhinsky District of Kamchatka Territory. Altogether 42 localities were investigated: 35 standard sample plots (20 x 20 m in forest communities and 10 x 10 m in shrub communities, tundras or swamps, otherwise in natural boundaries of the community), where the lichen diversity on each substrate was described as detailed as possible, and 7 additional plots, where only individual substrates and species were recorded. All geographical coordinates are given in the coordinate system WGS 1984.

Chromatography was performed by Irina S. Stepanchikova according to the standard techniques of high performance thin-layer chromatography using solvent systems A and B (Orange et al., 2001). The nomenclature of taxa generally follows recently published checklists for Scandinavia, Alps and North America (Nordin et al., 2011; Hafellner, Türk, 2016; Esslinger, 2018) and special taxonomic papers and monographs (Jahns, 1981; Dombrovskaya, 1996; Fryday, 2002; Halonen et al., 2009; Kukwa, 2011; Westberg, Arup, 2011; Spribille et al„ 2014; Davydov, 2017; Sheard et al, 2017; Zhdanov, 2017). The specimens were mainly identified by DH, Irina Stepanchikova, and Teuvo Ahti (Cladonia spp.), if otherwise, the identifier's names are indicated in the species list. Representative specimens are deposited in the herbaria of the Botanical Museum, University of Helsinki (H), Komarov Botanical Institute RAS (LE), and Department of Botany, St. Petersburg State University (LECB).

Results and discussion

An annotated list of species of Parapolsky Dale and vicinities is presented below. The species reported for the first time for the Kamchatka Territory are marked with !, lichenicolous fungi with #, non-lichenized fungi with +. Each species is accompanied with the list of substrates and localities. Lichen substances are given for TLC-analyzed specimens. The frequency of occurrence within the study area was estimated and is indicated in square brackets: [RJ "rare — single record" — the species was found once, [R] "rare" — recorded in 2-7 standard sample areas or more than in one additional plot, [O] "occasionally"— 8-14, [F] "frequent"— 15-21, [C] "common"— 22-28, [VC] "very common"— 29-35 standard sample areas (the latter category is absent in the analyzed material). For the species known from the Kamchatka Territory and/or neighboring regions, abbreviations of the regions are listed: Ala — Alaska, Chu — Chukotka Autonomous Area, Kam — Kamchatka Territory [within the limits of Kamchatka Peninsula and Commander (Komandorskie) Islands], Mag — Magadan Region, Yak — Republic of Sakha (Yakutia). References are given after each abbreviation (in brackets), one for each region; numbers correspond to those in the list of publications (see Material and methods). Special comments are given when needed.

The revealed diversity of lichens and allied fungi of Parapolsky Dale counts 315 species: 300 lichens, 7 lichenicolous fungi and 8 non-lichenized saprobic fungi related to lichens. Altogether 46 species are published from the Kamchatka Territory for the first time, including Lecanographa grumulosa new to Russia, East Asia and Beringia; Cercidospora trypetheliza, Lecania dubitans, Pertusaria borealis, Piccolia ochrophora, Protoparmelia cupreobadia, Rimularia badioatra and Strangospora moriformis new to Russian Far East; Abrothallus bertianus, Cladonia strepsilis, Physciella melanchra, Rim-ularia badioatra, Sclerococcum parasiticum, Sphinctrina leucopoda and Strangospora moriformis new to Beringia. Although the list of lichenicolous fungi for the study area is obviously incomplete and needs special research, the lichen diversity has been studied rather comprehensively and is just predictably poor.

The most interesting habitats, including rocks, are concentrated on sloping edges of the Parapolsky Dale, the bottom is relatively monotonous and boring for lichenol-

ogist. The richest biotopes are rocky outcrops (147 lichen species, 46.7 % of the studied biota) and tundra of different types (139 species, 44.1 %). Relatively high is the lichen diversity of shrub communities (altogether 108 species, 34.3 %), dominated by Salix pulchra (54 species), Betula divaricata (51 species), Pinus pumila (45 species) and Alnus fruticosa (31 species). Forest communities are not common in Parapolsky Dale. The forest lichens count 89 species (28.3 % of the studied biota), of them 73 species were recorded in floodplain forests, and 36 species only — in stone-birch forest. Bogs occupy significant part of the study area, but they have relatively poor lichen biota (78 species, 24.8 %). An average number of species per standard sample plot is 33.8+3.5: 11-34 species per sample plot in shrub communities, 3-42 in bogs, 33-57 in forests, 11-77 in tundras, and 93-98 in rocky outcrops.

Most diverse are epiphytic lichens (124 species, 39.4 % of the studied biota), the richest phorophytes are Salix pulchra (46 species), Populus suaveolens (43 species), Salix arbutifolia and Pinus pumila (38 species each), Alnus fruticosa (35 species), Betula divaricata (33 species), B. ermanii (27 species), Salix udensis (15 species); few lichens were also recorded on bark of Salixschwerinii and Sorbus sibirica (8 species each), Betula exilis (7 species), Vaccinium uliginosum (5 species), Rhododendron aureum (3 species). Soil is the second richest substrate, it has 114 species (36.2 % of the studied biota). Rocks are rare in Parapolsky Dale and occur only on its boards. Altogether 95 saxicolous species (30.2 %) were recorded; the lichens found here are typical for siliceous (non-calcareous) stones. Deadwood is poor represented and has relatively low lichen diversity (21 species, 6.7 % of the studied biota); 19 species (6.0 %) were found on mosses, 14 species (4.4 %) — on plant debris, 10 species (3.2 %) — on lichen thalli (including 7 fungi and 3 lichens), also 3 species were recorded on reindeer horn, and 2 saprobic fungi — on resin of Pinus pumila.

Within the study area, the majority of species have rare [R] frequency of occurrence (altogether 270 species or 85.7 % of the studied biota; of them, 117 were recorded once). Only two species (0.6 %) — namely, Cladonia amaurocraea and Cladonia arbuscula — are "common" [C], 16 species (5.1 %) were found "frequently" [F] (Ce-traria laevigata, C. sepincola, Cladonia cornuta, C. gracilis, C. pyxidata, C. rangiferina, C. stygia, Flavocetraria cucullata, F. nivalis, Lecanora fuscescens, L. symmicta, Melano-halea olivacea, Ochrolechia frigida s. l., Parmeliopsis ambigua, Thamnolia vermicularis, Vulpicidapinastri), and 27 species (8.6 %) — "occasionally" [O].

Comparison with neighboring regions (Kamchatka Peninsula, Chukotka, Magadan Region, Yakutia and Alaska, for most of them at least 600-1000 lichen species have been reported) shows that the lichen flora of Parapolsky Dale contains almost no specific species. Half of the studied biota (150 species) are known from all adjacent regions (Kamchatka, Chukotka, Magadan, Alaska) and Yakutia. Most species recorded in Parapolsky Dale are known also from Alaska (288 species, 91.4 % of the studied lichen biota), Kamchatka outside Koryakia (278 species, 88.3 %), Yakutia (241 species, 76.5 %), Chukotka (219 species, 69.5 %) and Magadan (178 species, 56.5 %). Further statistical similarity analysis of species lists would show obviously different degree

of knowledge of regional lichen floras: e. g., Alaska is well-studied, unlike Magadan. Anyway, the obtained numbers are enough to show high similarity and low specificity of the studied biota relative to neighboring regions, including both Beringian (Kamchatka, Chukotka, Alaska) and more remote (Magadan, Yakutia) territories.

Most species discovered in Koryakia have rather wide geographical ranges. Of special interest are species supposed to be Amphiberingian (Thomson, 1984) in wide sense, or endemic for North Pacific and adjacent territories (including Eastern Siberia and Yukon): Hypogymnia pseudophysodes, Stereocaulon spinosum (both known from Asia only), Amygdalaria subdissentiens, Cetraria kamczatica, Cladonia kanewskii, C. nipponica, C. wainioi, Ochrolechia subplicans, Pilophorus vegae, Stereocaulon apoca-lypticum, and S. wrightii. Most of these species, however, are known not from Beringia only, but also from neighboring inland territories (e. g., Yakutia). Some other species were considered before as Amphiberingian as well (e. g., Asahinea spp., Cetrelia alaska-na), but nowadays their ranges are known to be wider, up to circumpolar in some cases. However, the distribution of lichen species in Northern Asia requires further studies.
