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 (Litsch.) Ryvarden, Mycostilla vermiformis (Berk. & Broome) Spirin & Malysheva, Proterochaete adusta (Burt) Spirin & V. Malysheva, Pseudotomentella alobata Svantesson, Pseudoxenasma verrucisporum K.H. Larss. & Hjortstam, Sistotrema subtrigonospermum D. P. Rogers, Spiculogloea minuta P. Roberts, Tomentella botryoides (Schwein.) Bourd. & Galz., Tomentella neobourdotii M.J. Larsen, Tomentella subtestacea Bourdot & Galzin, Tomentella subpilosa Litsch., Tulasnella anguifera P. Roberts, and Tulasnella interrogans P. Roberts. Proterochaete and Pseudoxenasma are new genera to Finland. We also present the record of Caudicicola gracilis Kotir., Kulju & Miettinen 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.

Wood residues from forestry industries can be potential raw materials for specialty and edible mushroom production. The aim of this study was to evaluate the suitability of wood residues for the cultivation of Ganoderma lucidum originating from boreal forests. The substrates tested included sawdust and wood chips of Betula spp., Populus tremula, Picea abies, Pinus sylvestris and Larix sp. The suitability of the substrates and the ability of the strains to develop fruiting bodies and produce &beta, glucan were evaluated. Fruiting body formation was supported by applying two different cold shock treatments to substrate bags. The highest yields were observed with MUS192 strain and Betula spp. and P. tremula wood-based substrates. &beta, Glucan content in the fruiting bodies was highest with the MUS75 and P. tremula wood-based substrate. Based on these findings, the combination of P. tremula wood residues and the MUS192 strain is proposed to enhance the yield and &beta, glucan content of the fruiting bodies. A cold treatment of 5 &deg, C is suggested to induce primordia formation and to increase fruiting probability. This is the first time that strains of G. lucidum originating from boreal forests have been compared and successfully cultivated simulating commercial indoor cultivation.
