НАХОДКИ НОВЫХ И РЕДКИХ ВИДОВ ДЛЯ ЛИХЕНОФЛОРЫ ЗАПОВЕДНИКА «ПАСВИК» (МУРМАНСКАЯ ОБЛАСТЬ)
NEW RECORDS FOR LICHEN FLORA OF PASVIK RESERVE (MURMANSK REGION)

Summary/Abstract: The Pasvik State Nature Reserve is located in the north-western part of Murmansk Region. The reserve is important for the conservation of lichen diversity because it represents the northernmost, mainly undisturbed old-aged forests of the North-Western European part of Russia. The main goals of the expedition in 2017 was to study the lichen diversity of the old-aged pine and spruce forests and mountain tundra of Kalkupya Mt. Based on the material, collected mainly in 2017 and partially in 2015–2016, 29 species and 4 genera (Athelia, Bryostigma, Leptorhaphis, Sarea) are reported new to the Pasvik Reserve, including 26 lichenized species, 2 lichenicolous fungi, and 1 saprobic fungus. Six species are new to the biogeographic Province Lapponia Petsamoënsis. In addition, eleven rarely collected species are also reported. Detailed characteristics of their localities are presented. The annotated listing of species is given. New localities for six species from the Red Data Books of Murmansk Region and Russia (Arthonia vinosa, Bryoria fremontii, B. nitidula, Chaenotheca gracillima, Chaenothecopsis nigra and Lichenomphalia hudsoniana) are reported. As a result, the reserve accounts for 506 lichenized species, 37 lichenicolous species, and 13 saprobic fungi. Therefore, 42 % of the known species diversity of lichen flora is located in Murmansk Region.
