This paper provides additions to the biota of aphyllophoroid fungi of the Solovetsky Archipelago. To date, the list includes 307 species of aphyllophoroid fungi, 22 of them are found only in the territory in question. A previously published list was supplemented with 31 species of aphyllophoroid fungi, including 9 species new for the Arkhangelsk Region (Craterellus tubaeformis, Hypochnicium erikssonii, Phellodon melaleucus, Pterula gracilis, Sistotrema alboluteum, Trechispora invisitata, T. kavinioides, T. stevensonii, Tubulicrinis accedens). In addition, new data on 13 species of ascomycetes, including 6 new for the Arkhangelsk Region (Gyromitra infula, Humaria hemisphaerica, Hypoxylon fragiforme, Peziza badia, Trichoderma pulvinatum, T. viride), 3 species of dacrymyce-tes and 39 species of agaricomycetes, including 19 new for the region (Amanita fulva, A. muscaria, Boletus edulis, B. paluster, Clitocybe gibba, Coprinus comatus, Cortinarius armillatus, C. caperatus, C. sanguineus, C. traganus, Laccaria laccata, Lachnella albo-violascens, Lycoperdon perlatum, L. utriforme, Mycena haematopus, Pholiota squar-rosa, Pleurotus ostreatus, Russula aeruginea, Sebacina grisea) are provided. The state of knowledge about aphyllophoroid fungi on different substrates was analyzed. The correlation between the number of species and the habitat was discussed. The number of species increased especially notably along with stand density. Quite high substrate specificity was demonstrated. Almost every fifth of the species that we found only on the main forest-forming tree species was encountered sporadically. The Turing coefficient for the Solovetsky Archipelago is 67.3 %. The territory has been found to harbor 17 species listed in Red Data Books of adjacent areas and 33 indicator species, including 24 indicators of old-growth and 9 of very old spruce and pine forests. The forests of the archipelago can therefore be considered particularly valuable. The group of aphyllophoroid fungi has been studied quite thoroughly, while data on other groups of macromycetes are still scarce.
