NEW RECORDS OF RARE AND THREATENED SPECIES IN THE LICHEN FLORA OF PASVIK RESERVE (MURMANSK REGION)

Summary/Abstract: The main goal of the field expedition in 2018 was to study the lichen diversity of the old-aged forests in the central and northern parts of the Pasvik Reserve. According to the materials, collected in 2018, ten species and three genera (Coenogonium, Echinothecium and Schaereria) are reported as new to the Pasvik Reserve, including eight lichenized species (Arthonia radiata, Bacidina phacodes, Chaenotheca laevigata, Coenogonium pineti, Gyalecta geoica, Lecidea leprarioides, Micarea incrassata, and Schaereria cinereorufa) and two lichenicolous fungi (Echinothecium reticulatum and Muellerella lichenicola). Six species are new to the biogeographic province of Lapponia petsamoënsis. In addition, nine rarely collected species (Bacidia igniarii, Biatora albohyalina, Biatora vernalis, Caloplaca caesiorufella, Catinaria neuschildii, Megaspora verrucosa, Micarea micrococca, Parvoplaca tiroliensis and Placynthium asperellum) are reported. Detailed characteristics of their localities and notes on some species are given. New localities for five species from the Red Data Books of the Murmansk Region (Arthonia vinosa, Chaenotheca gracillima, Chaenotheca stemonea, Thelocarpon superellum and Verrucaria latebrosa) are reported.
