Based on field research in the Murmansk Region in the past two years, twenty lichen species (Acolium karelicum, Bacidina inundata, Biatora chrysantha, B. efflorescens, Bryoria glabra, Hymenelia rhodopis, Lecanora albellula, L. anopta, L. cadubriae, Lecidea albohyalina, Lepraria elobata, L. jackii, Micarea melaena, M. misella, Rhexophiale rhexoblephara, Thelidium submethorium, Verrucaria hydrela, Xylographa pallens, X. trunciseda, Xylopsora caradocensis) and three lichenicolous fungi (Dactylospora deminuta, Homostegia piggotii, Raesaenenia huuskonenii) are reported as new to the biogeographic provinces Lapponia Tulomensis, Lapponia Imandrae, and Kuusamo. Three species – Homostegia piggotii, Thelidium submethorium, and Xylographa trunciseda are reported for the Murmansk Region for the first time. The globally rare hydrophilic lichen Thelidium submethorium was found on the southern shore of Lake Kuolajärvi (Kuusamo) on willow branches submerged in water. This is second finding of this species in Russia and the third in Northern Europe. Xylographa trunciseda was found on pine wood in the nature-monument area of regional significance “Pines at the northern limit of the distribution range” (Lapponia Tulomensis). Lichenicolous fungus Homostegia piggotii was recorded on Rakhmoiva Mountain (Kuusamo). The new records for the lichen Bryoria glabra in the vicinity of Polyarnye Zori town and the lichenicolous fungus Raesaenenia huuskonenii from Isokumpu locality, situated to the west of the Alakurtti settlement, represent their second detections in the Murmansk Region. Fifteen new species were found in the biogeographic province of Kuusamo, four species – in Lapponia Tulomensis, and two species – in Lapponia Imandrae. The species Lepraria jackii is new to the lichen flora of the Lapland Nature Reserve. Information about the localities, ecology and collection dates is presented for all the said species. The distribution of these species in the Murmansk Region and in adjacent territories is outlined.
