Abstract: Knowledge of the distribution and occurrence of aphyllophoroid and heterobasidioid fungi in Finland is continuously expanding. Here, we present 26 species new to Finland: Amylocorticium laceratum (Litsch.) Hjortstam & Ryvarden, Artomyces piperatus (Kauffman) Jülich, Basidiodendron glaucum Spirin & K.H. Larss., Basidiodendron globisporum Spirin & Malysheva, Clavariadelphus mucronatus Wells & Kempton, Clavulina perplexa E. Campo, Franchi & M. Marchetti, Clavulina reae Olariaga, Dichostereum effuscatum (Cooke & Ellis) Boidin & Lanq., Elaphocephala iocularis Pouzar, Gloeocystidiellum kenyense Hjortstam, Helicogloea pellucida Spirin & Malysheva, Hirticlavula elegans J.H.Petersen & Læssøe, Lindtneria leucobryophila (Henn.) Jülich, Luellia furcata K.H.Larss. & Hjortstam, Myxarium crystallinum D.A.Reid, Myxarium fugacissimum (Bourdot & Galzin) Malysheva & Spirin, Myxarium grilletii (Boud.) D.A.Reid, Myxarium minutissimum (Höhn.) Spirin & Trichies, Paullicorticium globosum Oberw., Polyozellus flavovirens (Höhn. & Litsch.) Svantesson & Kõljalg, Protoacia delicata V. Spirin & V. Malysheva, Ramariopsis hirtipes (Fr.) Corner, Repetobasidium conicum (Oberw.) J. Eriksson & Hjortstam, Serendipita vermifera (Oberw.) P. Roberts, Thujacorticium zurhausenii (Bres.) Nakasone, and Tretomyces lutescens (J. Erikss. & Ryvarden) K.H. Larss., Kotir. & Saaren. We also report 132 new records of 79 rare or seldom collected species, and 137 species new to a specific subzone of the boreal forest vegetation zone in Finland. These records contain notes on the substrata and the ecology and distribution of the species new to Finland are briefly discussed.
