Five species of aphyllophoroid fungi (Athelia subovata Jülich et Hjortstam, Boidinia furfuracea (Bres.) Stalpers et Hjortstam, Hypochnicium erikssonii Hallenb. et Hjortstam, H. wakefieldiae (Bres.) J. Erikss., Trechispora byssinella (Bourdot) Liberta) were recorded for the first time for the Republic of Karelia. New data on the distribution of 29 species (10 are new for Karelia onegensis biogeographical province, 5 are new for Karelia olonetsensis and 4 are new for Karelia transonegensis) are also presented. 21 species were recorded for the first time for the Kivach Nature Reserve. Data on the localities, habitats and substrates of all these species are provided. The specimens are stored in the Mycological herbarium of the Karelian Research Centre RAS (PTZ) and Komarov Botanical Institute RAS (LE). The new findings broaden our knowledge of the distribution of aphyllophoroid fungi in the republic.
