Diversity and distribution of Finnish aphyllophoroid and heterobasidioid fungi (Basidiomycota) : An update

Abstract

Biogeographical and ecological knowledge of aphyllophoroid fungi has increased substantially after the publication of the Finnish aphyllophoroid checklist. In this paper, we describe the occurrence and distributions of both aphyllophoroid and heterobasidioid fungi in Finland. We introduce 13 species new to Finland: Hyphoderma lapponicum, Mycostilla vermiformis, Proterochaete adusta, Pseudotomentella alobata, Pseudoxenasma verrucisporum, Sistotrema subtrigonospermum, Spiculogloea minuta, Tomentella botryoides, Tomentella neobourdotii, Tomentella subtestacea, Tomentella subpilosa, Tulasnella anguifera, and Tulasnella interrogans. Proterochaete and Pseudoxenasma are new genera to Finland. We also present the record of Caudicicola gracilis for only the second time globally. Furthermore, we present 115 new records (locations) of 53 rare or seldom collected species. In addition, we report 96 species considered new to a specific subzone of the boreal forest vegetation zone in Finland. The records contain notes on the substrata, and the ecology and distribution of nationally new species and are briefly discussed.
