We present an updated checklist for Konevets Island (Leningrad Region, Russia). The revealed lichen biota comprises 435 species, including 378 lichens, 46 lichenicolous fungi and 11 non-lichenized saprobic fungi, of which 31 species (27 lichens and 4 lichenicolous fungi) are known only from collections made by Veli Räsänen (1917, 1938). Acremonium hypholomatis is reported for the first time for Russia; Caloplaca soralifera, Trapelia corticola, and Muellerella lichenicola for Northwestern European Russia; and Bacidia vermifera, Lecanora mughicola, Micarea contexta, Pyrenochaeta xanthoriae, Rhizocarpon disporum, Stigmidium squamariae and Xylographa difformis for Leningrad Region. From lichenological point of view, the most valuable habitats of Konevets Island are old-growth spruce forests. The studied lichen biota is rich and diverse and exceptionally well-preserved in comparison to the mainland part of Karelian Isthmus. It definitely deserves protection.

The updated checklist of Tuters Island (Leningrad Region, Russia) is presented. Of 331 species of recognized biota, 314 species of lichens, 16 lichenicolous fungi and one non-lichenized saprobic fungus are reported from Tuters Island. Of them, 202 species are new to the study area. Aspicilia epiglypta, Fuscidea praeruptorum, Micarea byssacea and Sarcogyne hypophaeoides are reported for the first time for Russia, Roselliniella stereocaulorum – for European Russia, Aspicilia polychroma, Carbonea vorticosa, Cercidospora stereocaulorum, Cladonia ciliata f. flavicans, C. rangiformis, Parmelia ernstiae, Plectocarpon cf. encausticum and Roselliniella cladoniae – for North-Western European Russia; Bachmanniomyces uncialicola, Bacidina sulphurella, Micarea botryoides, Miriquidica griseoatra and Stereocaulon nanodes are new to the Leningrad Region.

The aim of the study was to consolidate data on lichens of the genus Micarea Fr. from the Russian Far East. A total of 19 Micarea species were found to be known from this area. Micarea laeta and M. microareolata were new to Asia and Russia. Additionally, M. laeta was reported new to North America, Austria and Great Britain, M. microareolata – to North America, Czech Republic and Germany as well. Micarea contexta was reported new to Asia, Micarea adnata and M. tomentosa were reported new to the Russian Far East, M. hedlundii to the South of the Russian Far East and M. lignaria to the Sakhalin Region. Micarea turfosa was excluded from the list. The distribution of taxa and some differences between related species were discussed. Molecular data were obtained and used for phylogenetic analysis of Micarea contexta, M. laeta and M. microareolata.
