Abstract: Svalbard comprises several islands in the northern part of the Arctic Ocean. No larger tree species grow on the islands, but driftwood and construction timber have accumulated on the islands during the last 200 years. A thorough inventory of lignicolous basidiomycetous species was carried out on the island of Spitsbergen in 2001. The number of species found was 24. Of these fourteen were collected for the first time in Svalbard. Altogether 115 specimens were identified to species level. Corticioid fungi were the largest group with 84 specimens of 12 species. Some of the species found are seldom collected and poorly known also elsewhere. Only a few of the species were found in all the investigated areas. Half of the species were found only once or twice. Some of the new findings represent prominent range extensions.

Key words: Distribution, Finland, hemiboreal, Typhula

Abstract: During a work in the provinces Åland (Alandia, Ahvenanmaa) and Varsinais-Suomi 24 species of clavarioid fungi (Basidiomycota) were collected, including the rare Multiclavula mucida, Ramaria fennica, Ramariopsis crocea, Typhula capitata, T. olivascens and T. spathulata. New to Finland are Typhula abietina and T. sphaeroidea. Most of the species are widely distributed in the hemiboreal zone in Europe. The localities, habitats, substrates and short ecological notes for the new and some rare species are given.

Key words: Swedish myxomycetes, Swedish Taxonomy Iniative, Myxomycete distribution, Arcyria, Echinostelium bisporum, Echinostelium lunatum, Paradiacheopsis longipes

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.

Key words: Basidiomycota, Coleoptera, decay, ecology, Finland, fungivory

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.

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.

Key words: corticoid fungi, polypores, virgin forest

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.

Key words: Aphyllophorales, Basidiomycetes, clavarioid fungi, distribution, nemoral, relicts, Ural

Abstract: One hundred and eighteen clavarioid species are reported from the nemoral zone of the Ural Mts.. Eight of them, Ceratellopsis aculeata, C. terrigena, Lentaria corticola, Pistillaria quercicola, Ramaria broomei, R. lutea, R. subtilis and Typhula hyalina, are reported for the first time from Russia. The material consists of 1300 collections and observations, and according to these, the most frequent species are Clavulina cinerea, Macrotyphula juncea, Typhula erythropus, T. sclerotioides, T. uncialis and T. variabilis. These contain ca. 23 % of all observations, but only 5 % of all the species. In comparison with the boreal zone of the Urals, the nemoral zone consists less abundant species (1.7% / 14.6%) and more rare species (47.8% / 38.2%). Species like Clavulinopsis aurantiocinnabarina, Pistillaria quercicola, Ramaria broomei, R. lutea and Sparassis brevipes are considered to be relicts of Pliocen and Holocen periods. The most favorable habitats for the rare and relict species are discussed. The collecting sites are briefly described and descriptions of the new and rare species for Russia are given.

Key words: cluster analysis, Corticiaceae s.l., Querco-Piceetum, sample plot

Abstract: Inventories of corticioid fungi (Basidiomycetes) were carried out on four permanent 400 m² sample plots scattered over Belarusian Moraine Ridge. Selected coenoses belong to boreonemoral vegetation zone and the forests are dominated by spruce, aspen and oak, of Oxalis and Aegopodium types. The number of corticioid fungi in these forests was in average 37 species, which permits to evaluate Querco-Piceetum as the most species-rich forest type. The largest genera were Hyphodontia (5–7 species per plot) and Peniophora (3–4 species, respectively). In general, the more dead wood was produced by a host the higher was the number of fungal species inhabiting it. In this study spruce plays a minor role as a host for corticioid fungi (in boreonemoral forests), harbouring only a few species. Cluster analyses demonstrated that structure of fungal assemblages is dependent on the type of plant association, and in several cases also on geographical distance between the study sites.

Abstract: The paper summarizes field inventories of polypores and associated beetles in northwestern Finland (Lapland) in the years 2001–2004. The research area includes nearvirgin or old-growth forests of the Pallas–Yllästunturi National Park and the Pisavaara Strict Nature Reserve, one of the largest areas of protected forests in the country. Altogether 132 polypore species were found or (a few) documented from herbarium collections. Special attention was paid to those beetles that visit or inhabit polypores, either to consume their spores and mycelium, or living in polypore basidiocarps at larval stages. Beetle species compositions and their occurrences as larvae versus imagines differed according to the characteristics of polypore basidiomata. Four kinds (life cycles) of basidiomata were separated: ephemeral, annual sturdy, annual hibernating, and perennial. The selective effect of these life cycles over attracted beetles is extensively discussed with numerous examples. Parallels were found between the insects living in decayed wood versus mushrooms: while beetles of the ephemeral polypore hosts follow in their biology the “mushroom” pathway (pupating in soil debris), those living in perennial basidiocarps follow the “wood” pathway in both consuming the fungus and in pupating inside the decaying basidiocarp. The paper includes complete lists of polypores and polypore-linked beetles found in the study area. A number of wood-inhabiting fungi of other groups are listed, including observations of their beetle fauna. Also more theoretical aspects of the fungus–beetle interaction are discussed.
