Abstract: Two new genera of polypores (Basidiomycota) are described, Erastia Niemelä & Kinnunen, and Rhodonia Niemelä & K.H. Larsson. The following new combinations are presented: Antrodiella canadensis (Overh.) Niemelä, Erastia salmonicolor (Berk. & M.A. Curtis) Niemelä & Kinnunen, Oligoporus balsaminus(Niemelä & Y.C. Dai) Niemelä, Oligoporus immitis (Peck) Niemelä, Oligoporus persicinus (Niemelä & Y.C. Dai) Niemelä, Porodaedalea laricis (Jacz. ex Pilát) Niemelä, and Rhodonia placenta (Fr.) Niemelä, K.H. Larsson & Schigel. Porodaedalea niemelaei M. Fischer is considered to be synonymous with P. laricis, and Sarcoporia polyspora P. Karst. was found to be an older name for the species commonly known as Parmastomyces transmutans (Overh.) Ryvarden & Gilb. or P. mollissimus(Maire) Pouzar.

Key words: Basidiomycota, Ceriporiopsis albonigrescens, Ceriporiopsis aneirina, Ceriporiopsis balaenae, Ceriporiopsis cremea, Ceriporiopsis pseudogilvescens, Ceriporiopsis resinascens, polypore, taxonomy

Abstract: The polypore genus Ceriporiopsis is revised, and a new combination is proposed:Ceriporiopsis pseudogilvescens (Pilát) Niemelä & Kinnunen. It is the correct name for the species commonly known as C. resinascens (Romell) Doma?ski; the latter is a northerly taxon with narrower spores and less resinous basidiocarp. Also the related C. aneirina (Sommerf.) Doma?ski, C. balaenae Niemelä, C. gilvescens (Bres.) Doma?ski, C. albonigrescens Núñez, Parmasto & Ryvarden and C. cremea (Parmasto) Ryvarden are discussed and compared. The results are supplemented with an extensive list of spore size measurements and by a key to the species.

Key words: Aphyllophorales, Oligoporus, polyporaceous fungi, Postia hibernica, taxonomy

Abstract: The taxonomy of the Oligoporus hibernicus (Berk. & Broome) Gilb. & Ryvarden complex (Basidiomycota) is revised. The study is based on extensive herbarium material chiefly from northwestern Europe and the type material of the taxa involved. The examination of the type of Polyporus hibernicus Berk. & Broome revealed that the name has been misapplied. The name belongs to a taxon, which often has pale yellow basidiocarps and was often erroneously called Physisporus flavicans P. Karst. or Poria johnstonii Murrill, and recently described as Oligoporus septentrionalis Vampola. The name O. parvus Renvall is proposed for the species that has erroneously been called as O. hibernicus in northwestern Europe. Four morphologically very similar species are recognized in the O. hibernicus complex in Europe: O. hibernicus sensu typi, O. perdelicatus (Murrill) Gilb. & Ryvarden, O. simanii (Pilát) Bernicchia, and the new species O. parvus, which is reported from Finland, Norway and Sweden. O. perdelicatus has been collected from seven localities in eastern Finland and is here reported as new to Europe. The species are described and discussed in detail.

Key words: Cinereomyces, ecology, Junghuhnia, polypores, rare species, Skeletocutis, taxonomy, wood-rotting fungi

Abstract: A new species Junghuhnia vitellina Spirin is described, growing on Betula mandshurica in Russian Far East. Cinereomyces lenis (P. Karst.) Spirin, comb. nova is a so-called kelo fungus; its closest relative C. vulgaris (Fr.) Spirin, comb. nova has relatively wide set of hosts. The latter is new to Russia. Eleven species of Skeletocutis are discussed, and some data on their ecology are treated. S. chrysella Niemelä, S. subincarnata (Peck) Jean Keller and S. stellae (Pilát) Jean Keller are rare taiga species, growing on large spruce or pine trunks at late stages of wood-decomposition. S. biguttulata (Romell) Niemelä and S. brevispora Niemelä are locally common and found in both southern and northern parts of the study area. S. carneogrisea David and S. kuehneri David grow in association with Trichaptum species in virgin as well as managed coniferous forests. S. albocremea David is very rare; it was collected only once in old pine forest. S. kuehneri and S. papyracea David are new to Belarus.
