Key words: Basidiomycetes, Finland, Archipelago Sea, corticioid fungi, taxonomy

Abstract: Peniophorella tsugae, Phlebiella alnicola and Trechispora araneosa are reported as new to Finland. New records of Hastodontia halonata, Helicogloea lagerheimii and Peniophorella echinocystis are presented and notes of the habitats and substrates are given. Descriptions of the new species and H. halonata are given as well as microscopical drawings. The taxonomy of P. alnicola is briefly discussed and comparison between Peniophorella pallida and P. tsugae is made. Most new Finnish records derive from SW Finland, from forested islands of the Archipelago Sea and mainland coastline. Inventories were carried out during late summer and autumn 2008 and 2009. Hastodontia halonata is reported as new to Estonia.

Abstract: Wood-inhabiting fungi on Pinus sylvestris were examined in three old-growth forests in northern Sweden. A total of 16 rare species of aphyllophoroid fungi are reported. Among the species discussed are Antrodiella pallasii and Skeletocutis kuehneri which are successors of Trichaptum species and previously known from only a few localities in Sweden, and Byssoporia terrestris and Hydnellum gracilipeswhich are mycorrhizal species with specific ecological preferences. Three corticioid species from genera Ceraceomyces and Sistotrema represent possible new taxa.

Abstract: New records of Polyporus pseudobetulinus on willow species from Arkhangelsk Region (North of European Russia) were made. The differences between P. pseudobetulinus and the similar P. choseniae are generalized, highlighting spore variability and hyphal system. The two species are rather distant from each other. P. pseudobetulinus is characterized by dimitic hyphal system with a predominance of fibre hyphae, lack of clamps, and somewhat sigmoid spores, whereas P. choseniae has dimitic hyphal system with a predominance of skeleto-binding hyphae, clamps, and symmetrically fusoid basidiospores. The ecological preferences and distribution patterns of both species are discussed.

Abstract: Over 400 Finnish herbarium specimens of the hepatics Plagiochila asplenioides and the closely related P. porelloides were screened for the presence of fungi. The screening yielded ca. 200 recordings of bryicolous species belonging to the ascomycete genera Bryomyces, Dactylospora, Epibryon, Lichenopeltella, Octosporella, Pleostigma, and the anamorphic genus Epicoccum. With the exception of Epibryon plagiochilae, the species are new to Finland. They are described and illustrated. Their morphology, taxonomy and ecology are discussed and their distribution in Finland is mapped. A key is given to all known bryicolous fungi found on P. asplenioides (incl. P. porelloides).
