Abstract: Antrodia onychoides (Egel.) Ryvarden, earlier known from the type only, is reported as new to Finland. Its emended description is given, and its taxonomic position discussed. A. ramentacea (Berk. & Br.) Donk is reported from five localities in southern and south-eastern Finland, growing on corticated Pinus sylvestris. Gloeoporus gelatinosotubulosus (Pil.) Bond. ex Kartavenko has been collected from Finland for the first time, and the find is evidently the first outside the U.S.S.R. The species is brieny described, and its nomenclature is scrutinized. The occurrence of Inonotus dryophilus (Berk.) Murrill in Finland is substantiated, and earlier reports of the collections under the names I. dryadeus (Fr.) Murrill and I. hispidus (Fr.) Karst. are corrected. The species of Inonotus occurring in Finland are listed. Junghuhnia pseudozilingiana (Parm.) Ryv. is reported as new to Finland and Fennoscandia, and its identification and ecology are briefly discussed.
