The paper presents the first record for Russia of one species of ascomycota fungus, first records for the Republic of Belarus of one species of siphonous yellow-green algae and three species of lichenicolous fungi, first records for Kazakhstan and Uzbekistan of two and one species of lichens, respectively, and of first records for regions of Russia: one red alga for the Leningrad Region, one cyanobacteria for St. Petersburg, ten chrysophyte algae for the Leningrad Region, Komi Republic and Republic of Bashkortostan, one charophyte alga for the Yamal-Nenets Autonomous Area, one species of haptophyte algae for the Irkutsk Region, two species of siphonous yellow-green algae for the Chukotka Autonomous Area and Magadan Region, one species of rust fungus for the Komi Republic, seven lichenicolous fungi for the Murmansk and Tver regions, including one species new for Russia, six species of basidiomycetes for the Altai Territory, Republic of Tuva, and Yaroslavl Region; 25 species of lichens for the Amur, Murmansk, Tyumen regions, republics of Altai, Buryatia, Karelia, Komi, Tuva, Altai, and Krasnoyarsk territories, one species of liverwort for St. Petersurg, 13 species of mosses for the Penza, Tambov, Tula, Tyumen regions, Republic of Dagestan, and Nenets Autonomous Area, including one species new for Siberia. Data on their localities, habitats, distribution are provided. The specimens are kept in the herbaria AA, ALTB, GSU, HERZ, IBIW, KPABG, LE, LECB, MIRE, MSK, MW, NSK, ORIS, PKM, PZV, SYKO, TOB, UUH, VU, in the algological collection in the Laboratory of Cell Ultrastructure of the Limnological Institute SB RAS (LIN). Sequences of the 16S rRNA gene of the cultivated strain of a cyanobacterium and sequence of ITS1-5.8S-ITS2 nrDNA region of some specimens of fungi have been deposited in the GenBank (NCBI).
