Abstract

We contribute to the knowledge on the occurrences and distributions of both aphyllophoroid and heterobasidioid fungi in Finland. We present four species new to Finland, i.e. Helicogloea sebacea, Phanerochaete cremeo-ochracea, Steccherinum cremeoalbum, and Uncobasidium luteolum, as well as 46 new records (locations) of 34 rare or rarely collected species. Additionally, we report on 40 species considered new to a certain subzone of the boreal forest vegetation zone in Finland. These records contain notes on their substrata, and the ecology and distribution of nationally new species are briefly discussed.
