Key words: Abundisporus, Loweporus, Perenniporia, polypores, taxonomy

Abstract:  Four species of Abundisporus Ryvarden are described including two new combinations: A. pubertatis (Lloyd) Parmasto and A. subjlexibilis (Berk. & M.A. Curtis) Parmasto. Absorption spectra demonstrated uniformity of the pigments in this genus, but also in Loweporus tephroporus (Mont.) Ryvarden; to distinguish the species, statistical measurement of spore size have been used. Relations of the genera Abundisporus, Perenniporia and Loweporus are discussed.

Abstract:  A biogeographical analysis of East Asian polypores based on species lists and Dice’s similarity index is provided. A comparison of the temperate East Asian polypore mycota with those from other north temperate areas showed that most species belong to the north temperate element, but East Asia has the highest biodiversity and degree of endemism of all north temperate areas. East Asia and East North America share the highest amount of taxa. Furthermore, several species with their main distribution centres in the palaeotropics, Australia, and even the neotropics, occur in East Asia. Their presence in this area could be related to past geological events.

A new coprophilous species of Perichaena (Myxomycetes) from the Russian Arctic (the Taimyr Peninsula and the Chukchi Peninsula)

Key words: Perichaena taimriensis, coprophilous myxomycetes, ultrastructure, Russia, Arctic

Abstract:  Perichaena taimyriensis Novozh. & Schnittler is a new, undescribed coprophilous myxomycete species characterised by the absence of a capillitium and its pilate spore ornamentation. Collections from the Taimyr Peninsula and the Chukchi Peninsula, Russia, were recorded from dung of reindeer (Rangifer tarandus L.) in forest-tundra and tundra communities. A description of P. taimyriensis and scanning electron photographs are presented. Characters distinguishing this species from Perichaena corticalis (Batsch) Rostaf. var. liceoides (Rostaf.) G. Lister are given. The taxonomic limits of this species are discussed. Apparently, P. taimyriensis represents an intermediate taxon between Perichaena and Licea but can be tentatively placed within the genus Perichaena.

Key words: Cuba, cultural description, Hawaii, Himantia stellifera, Hyphoderma setigerum, Puerto Rico, Resinicium, sugar cane

Abstract:  Type specimens of three corticioid taxa described by E.A. Burt are reexamined. In 1917, Burt described two new species of Odontia, O. sacchari and O. saccharicola, on sugar cane from Cuba and Puerto Rico. Odontia sacchari is similar to the ubiquitous Hyphoderma setigerum (Fr.) Donk except for basidia that are consistently two-sterigmate and basidiospores that are slightly larger. The new combination Hyphoderma saccharum (Burt) Nakasone is proposed. Odontia saccharicola is morphologically similar to Resinicium bicolor (Fr.) Parmasto but differs in lacking clamp connections and producing smaller basidiospores. The new combination Resinicium saccharicola (Burt) Nakasone is proposed. Corticium granulare Burt, on herbaceous stems from Hawaii, is conspecific with Odontia saccharicola. Descriptions and illustrations of the H. saccharum and R. saccharicola are provided. In addition, a cultural description of R. saccharicola is presented.

Key words: Algae, corticolous, Licea microscopica, Licea operculata, Licea sambucina, Licea scintillans, Licea scyphoides, Myxomycetes, Sambucus nigra

Abstract:  The authors have each specialised in the moist-chamber culture of bark sampled from living trees and have recently initiated a special investigation of the bark of Sambucus nigra. The original description of Licea microscopica D.W. Mitch. is amended in the light of numerous recent collections and Licea sambucina D.W. Mitch. nov. spec. is described. Both taxa are abundant in many localities in S.E. England on alga-covered bark of Sambucus nigra L. Interesting collections of other spp. of Licea are reported, including L. scintillans McHugh & D.W. Mitch. nov. spec. which has previously been confused with L. iridis Ing & McHugh. Characters used to distinguish between aberrant forms of L. operculata (Wingate) G.W. Martin and L. scyphoides H.W. Keller & T.E. Brooks are outlined.

Abstract:  Descriptions and original iconography are given for the following tomentelloid basidiomycetes from the Iberian Peninsula: Tomentella badia, T. cinereoumbrina, T. fuscocinerea, T. bresadolae, T. bryophila, T. brevispina, T. neobourdotii, T. ramosissima and T. stuposa. Their distribution in the area is reviewed. T. brevispina is a new record to the Iberian Peninsula. T. badia, T. fuscocinerea, T. bryophila and T. neobourdotii are new to Portugal.

New records of Funalia trogii, Perenniporia tenuis and Polyporus pseudobetulinus from Finland, with notes on their habitat requirements and conservation implications

Abstract:  We report the results of three extensive surveys between 1996 and 1999 on the polypore flora of dead aspen trees (Populus tremula L.) in eastern Finland. These surveys yielded several new finds and new information on the habitat requirements of three polypore species classified as endangered in Finland: Funalia trogii (Berk.) Bondartsev & Singer, Perenniporia tenuis (Schwein.) Ryvarden and Polyporus pseudobetulinus (Pilát) Thorn, Kotir. & Niemelä. Our observations confirm that F. trogii is a thermophile preferring sun-exposed habitats. Similarly, all new records of P. tenuis were made in open habitats. P. pseudobetulinus has also been found occasionally on retained aspens in clear-cut areas, although it is usually located in old-growth forests. Our results suggest that these and other threatened species with similar habitat requirements could possibly survive even in a managed forest landscape, provided that potential host trees are retained in sufficient numbers. Most of the new records derive from trees killed by notching or girdling, indicating that suitable host trees for these species can be created even by killing trees. However, notching or girdling should be used with caution because it will reduce the availability of aspen trees in the future.

Key words: charred wood, forest fire, fruit body evolution, Hydnellum, molecular phylogeny, mycorrhiza, Thelephorales

Abstract:  Taxonomy and phylogeny of Hydnellum gracilipes (P. Karst.) P. Karst. (Thelephorales, Hymenomycetes) was revised. The species is characterized by soft and resupinate sporocarps, and the morphology supports a close relationship with tomentelloid fungi. The phylogenetic interpretation of the sequence data from the 5′ end of nuclear large subunit (nucLSU) rDNA showed, however, that the closest relatives of H. gracilipes are found in the genus Hydnellum P. Karst. The evolution of the resupinate fruitbody is outlined. The ecology of the species is discussed and it is proposed that H. gracilipes is a mycorrhizal fungus. Six new localities are listed.

Key words: Aphyllophorales, arctic, timber, Yakutia

Abstract:  A total of 42 species of wood-inhabiting fungi (mostly Aphyllophorales) were collected in the Republic of Sakha (Yakutia) in the vicinity of the town of Tiksi, which is situated in treeless tundra. All species grew on timber. The most common species proved to be Dacryobolus sudans (Alb. & Schwein. : Fr.) Fr., Hyphoderma praetermissum (P. Karst.) J. Erikss. & A. Strid, H. setigerum (Fr.) Donk, Peniophora incarnata (Pers. :Fr.) P. Karst., Stereum sanguinolentum (Alb. & Schwein. :Fr.) Fr. and Trametes ochracea (Pers.) Gilb. & Ryvarden. Athelia pyriformis (M.P. Christ.) Jülich, Subulicium lautum (H.S. Jacks.) Hjortstam & Ryvarden and Syzygospora mycophaga (M.P. Christ.) Hauerslev are reported from Russia for the first time and some microscopical details of them are given. The dispersal ability and the probable dispersal routes of the species are briefly discussed.
