Abstract: The current inventory of myxomycetes within the frames of the Swedish Taxonomy Initiative project continues to yield records of species not previously known to Sweden. A selection of twenty species here formally reported for the first time gives a total of 210 species so far known from Sweden. Among notable records are Echinostelium bisporum and E. lunatum, the two smallest species of myxomycetes known, fruitbodies of the first species rarely exceeding 25 um in height. Both species are impossible to detect using standard methods for myxomycetes and are probably far more common than the few widely scattered records in the world so far would suggest. Paradiacheopsis longipes is reported for the third time, previously known only from the Netherlands and China. Additional records are awaiting publication, but the delimitation and circumscription of several taxa require further study. Continued field-work supplemented with so-called moist chamber cultures will further increase the number of species known to occur in Sweden. Distribution patterns of myxomycetes are discussed briefly.

Abstract: The paper deals with adult beetles attracted by wood-rotting agarics of the genera Armillaria and Pleurotus, plus those collected on the oak-decaying polypore Grifola frondosa. The interrelations of 14 species (110 samples) of fungi and 78 species (1691 individuals) of beetles are discussed. More close relationships, such as fungivory of larvae of Coleoptera are also treated. In southern Finland larvae of Cychramus (in Armillaria) and Triplax (in Pleurotus) are able to utilize fleshy wood-rotting fungi. The majority of beetles were recorded as adults, including 52 (67%) species of Staphylinidae.

Abstract: Twenty one Typhula (Pers.) Fr. species and one Pistillaria Fr. species are reported from Finland. Five species are new for the country, viz. Typhula capitata (Pat.) Berthier, T. culmigena (Mont. & Fr.) J. Schröt., T. hyalina (Quél.) Berthier, T. spathulata (Peck) Berthier, and T. struthiopteridis Corner. Most of the species are common. The localities, habitats, substrates and short ecological notes for the new species are given.

Abstract: Anomoloma albolutescens (Romell) Niemelä & K.H. Larss. is found for the first time in European Russia. Ecology and distribution of this species are briefly reviewed.Poria buxi Bondartsev is a later synonym of Hyphodontia flavipora (Cooke) Sheng H. Wu. Hyphodontia radula (Schrad. : Fr.) E. Langer & Vesterholt was found to be widely distributed in hemiboreal European Russia. Lindtneria trachyspora (Bourdot & Galzin) Pilát and Sistotrema dennisii Malençon are reported as new to Russia.Sistotrema brunneolum Spirin & Zmitr. is described as a new species closely related to S. alboluteum (Bourdot & Galzin) Bondartsev & Singer. The new species is characterized by relatively firm, brownish, porioid basidiocarps, two- or four-sterigmate basidia, and short-cylindrical to ellipsoid, thick-walled spores. The isolated position of both S. brunneolum and S. alboluteum within the genus Sistotrema is discussed.
