    The paper presents a list of lichens for the Innvika Bay, which includes 157 lichenized and 2 lichenicolous fungi. Alectoria gowardii and Peltigera elisabethae are new to Svalbard. Furthermore, 36 other species were found new to Nordaustlandet. Twenty-seven species are rare on Svalbard, among them Aspilidea myrinii, Candelariella borealis, Gyalecta erythrozona, Miriquidica deusta, Rhizocarpon viridiatrum (reported for the second time), and Aspicilia cinerea, Cetraria nigricans, Cladonia arbuscula, Cystocoleus ebeneus, Lecidea ecrustacea, Peltigera frippii, Rhizocarpon eupetraeoides, Rinodina terrestris, Stereocaulon cumulatum, Toninia squalida, Verrucaria hydrela. Localities, substrates and distribution in Svalbard are given for each species. For rare and extremely rare species, all known locations are given. For some species, differences from closely related species are given

    Floristic check-lists were compiled for the first time for Duvefjorden Bay on Nordaustlandet, Svalbard, based on field work in July 2012 and on data from literature and herbaria. The check-lists include 172 species of lichens and 51 species of vascular plants. Several species rare in Svalbard and in the Arctic were discovered: Candelariella borealis was new to Svalbard. 51 lichen species were newly recorded on Nordaustlandet and 131 lichen species were observed in the Duvefjorden area for the first time. Among lichen species rare in Svalbard and in the Arctic the following can be mentioned: Caloplaca magni-filii, C. nivalis, Lecidea silacea, Phaeophyscia nigricans, Polyblastia gothica, Protothelenella sphinctrinoidella, Rinodina conradii, Stenia geophana, and Tetramelas pulverulentus. Two species of vascular plants, Saxifraga svalbardensis and S. hyperborea, were found new to the Duvefjorden area. The investigated flora is represented mostly by species widespread in Svalbard and in the Arctic. Although Duvefjorden area is situated in the northernmost part of Svalbard, its flora is characterized by relatively high diversity of vascular plants and lichens. Apparently this is due to the influence of the warm North Atlantic Current

    Forty-four new lichen species and one lichenicolous fungus have been identified as a result of studies of the lichen biota of the Franz Josef Land archipelago. Bryocaulon hyperboreum was reported for the first time from Russia. Gyalecta hypoleuca and Umbilicaria maculata were first identified in the Arctic. Arctocetraria andrejevii, Brodoa oroarctica, Candelariella borealis, Cercidospora stereocaulorum, Massalongia carnosa, Miriquidica nigroleprosa, M. plumbeoatra, Myriolecis zosterae var. palanderi and Polyblastia gothica are new to the Arkhangelsk Region; and Arthrorhaphis citrinella, Mycoblastus alpinus, Racodium rupestre, Rhizocarpon ferax, Scytinium intermedium, Stereocaulon glareosum are new to the Arctic part of the Arkhangelsk Region. Species new to Arkhangelsk Region, Arctic and Russia are supplied with information on distribution in neighboring regions and world and on differences from closely related species. The checklist of the Franz Josef Land archipelago thus includes 277 species and 6 varieties of lichenized and 43 lichenicolous fungi to date

    The lichens of the northern shore of the Gulf of Finland in the limits of St. Petersburg, Russia – diversity on the edge of the megapolis

    Get PDF
    We present a lichen checklist for the northern shore of the Gulf of Finland in the limits of St. Petersburg, Russia. This area has diverse lichen biota within the city limits, and has been comprehensively studied since 1893, which gives a good base for analysis of historical changes in lichen diversity. The documented lichen biota comprises 469 species (430 lichenized, 24 lichenicolous, 3 facultatively lichenicolous, and 12 non-lichenized saprobic fungi), of them 191 species are known from herbaria and literature for the period before 1991, and 436 species were recorded since 1991 to 2019. Thirty-three taxa were excluded from the lichen list of the study area as erroneous or dubious records. Altogether 48 species are new to St. Petersburg, including: Lecidea malmeana and Micarea czarnotae – new to Russia; Caloplaca lucifuga, Gyalecta nigricans, Micarea soralifera – new to European Russia; Agonimia flabelliformis, Endococcus verrucosus, Lecania turicensis, Micarea fallax, M. tomentosa, Xanthomendoza huculica – new to Northwestern European Russia; Lichenoconium lichenicola, Ramalina europaea, Sarcogyne hypophaea – not known also from the Leningrad Region. The studied lichen biota is moderately rich compared to other city territories. The history of economic development of the region has caused its serious transformation, degradation of natural habitats and therefore partial loss of lichen diversity. At the same time, human-made substrates and anthropogenic plant communities are inhabited by lichens, including species unknown in the natural habitats of the study area. However, 44 species recorded in the study area are red-listed in St. Petersburg, with 13 of them known only from historical collections. Forest communities, as well as historical parks, in NW part of St. Petersburg are important source of biodiversity on regional level nowadays and hopefully in future, and deserve protection

    This paper contributes to the studies on the lichen diversity of Barentsøya. It covers 211 species, of which four ( Buellia schaereri, Myriolecis zosterae var. palanderi, Rhizocarpon furfurosum, R. leptolepis) are reported for the first time for the Svalbard archipelago. Additionally, 84 of the species are reported for the first time for Barensøya. Our study includes 2 subspecies as well, both new for Barentsøya. Thirty-six species (16.8% among the identified species) are rare in Svalbard, whereas more than two thirds (70.1% from identified in the Barensøya) are relatively widespread species in Svalbard and the Arctic
