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.

Highlights

A wealth of knowledge on the occurrence and distribution of both aphyllophoroid and heterobasidioid species in Finland has accumulated after the publication of the Finnish aphyllophoroid checklist (Kotiranta et al 2009): comprising a total of 75 species new to Finland (Kotiranta, unpublished), 355 records of rare species, and 485 species new to some region (e.g. Kunttu et al 2016, 2018, 2019)
We present new records of aphyllophoroid and heterobasidioid fungi in Finland, considering three types of records: 1) species new to Finland, 2) rare or seldom collected species with a maximum of 10 previous records in Finland, and 3) species that are new to a certain subzone of the boreal vegetation zone in Finland
We present four species new to Finland: Helicogloea sebacea (Bourdot & Galzin) Spirin & Trichies, Phanerochaete cremeo-ochracea (Bourdot & Galzin) Hjortstam, Steccherinum cremeoalbum Hjortstam, and Uncobasidium luteolum Hjortstam & Ryvarden

Summary

Introduction

A wealth of knowledge on the occurrence and distribution of both aphyllophoroid and heterobasidioid species in Finland has accumulated after the publication of the Finnish aphyllophoroid checklist (Kotiranta et al 2009): comprising a total of 75 species new to Finland (Kotiranta, unpublished), 355 records of rare species, and 485 species new to some region (e.g. Kunttu et al 2016, 2018, 2019). We present new records of aphyllophoroid and heterobasidioid fungi in Finland, considering three types of records: 1) species new to Finland, 2) rare or seldom collected species with a maximum of 10 previous records in Finland, and 3) species that are new to a certain subzone (section) of the boreal vegetation zone in Finland. We considered both aphyllophoroid and heterobasidioid fungi in their broader sense, and their species composition roughly follow that of Hansen and Knudsen (1997), with the exception that the gastromycetoid genera are excluded. Roberts and Eocronartium G.F.Atk. (Pucciniomycotina) are included, since the Finnish checklist of aphyllophoroid fungi considered them (Kotiranta et al 2009)
