Key words: Africa, fungi, Myxomycetes, Tanzania, tropics

Abstract:  During the rainy seasons in May and December 1988 and in December 1989, Myxomycetes were collected in northeastern and southern Tanzania, with 53 species found. According to the literature, all are new to Tanzania, and the following seven are new to Africa: Didymiun bahiense Gottsb., Paradiachea cylindrica (Bilgram) Hertel, Physarum notabile Macbr., P. psittacinun Ditmar, P. superbun Hagelst., Tubifera bombarda (Berk. & Br.) Martin, and T. microsperma (Beck. & Curt.) Martin. A lectotype for Arcyria globosa Schw. is selected. Myxomycetes were more abundant in the montane forest belt than at other elevations, and no significant difference could be noticed in species composition between the two rainy seasons, May and December. Species belonging to the order Licheales were found only on decaying wood, and of the Physarales the majority of the specimens were found on litter.

Key words: Anthracoidea irregularis, Carex pallens, Finland, nomenclature

Abstract:  As Carex pallens (Fristedt) Harmaja (Cyperaceae) has been recognized as a valid species, this sedge becomes the fourth principal Nordic host species known for the ovaricolous smut fungus Anthracoidea irregularis (Lira) Boidol & Poelt. Carex digitata L. x pallens is reported as a new host of A. irregularis. The smut has been found at six Finnish localities on C. pallens and at two on C. digitata x pallens. Both smut-host combinations are new to Finland. Anthracoidea irregularis U. Braun & Hirsch is considered an illegitimate name, being superfluous and a later homonym of A. irregularis (Liro) Boidol & Poelt.

Key words: Boreo-continental, Finland, Northern Boreal, polypores, primeval forest, Skeletocutis lenis, threatened fungi, timberline

Abstract:  Seventy-seven polypores are listed from virgin forests in northeastern Finland, ten of which are classified as threatened in Finland. The host range and abundance of each species are given. The occurrences of threatened and also some abundant species are treated with special reference to their distribution and habitat ecology. Fungal species compositions of spruce, pine and birch forests are compared: 33 species were recorded growing on Picea abies subsp. obovata, 31 species on Pinus sylvestris and 24 species on Betula pubescens. The economically most harmful pathogenic polypores found in the swdy area were Climacocystis borealis (Fr.) Kotl. & Pouz., Fomes fomentarius (L.: Fr.) Fr., Fomitopsis pinicola (Sw.: Fr.) Karst., Inonotus obliquus (Pers.: Fr.) Pil., Onnia leporina (Fr.) Jahn, Piptoporus betulinus (Bull.: Fr.) Karst. and Porodnedalea chrysoloma (Fr.) Fiass. & Niemelä Problems in estimating abundances of wood-rotting fungi are discussed. The term boreo-continental is proposed to replace the misinterpreted concept ‘taiga species’ for a northeastern distributional pattern. The ecological role of wood-rotting fungi in a northern ecosystem, and yearly variation in fruit-body emergence are discussed. A new combination Skeletocutis lenis (Karst.) Niemelä is proposed and the background of the combination is briefly discussed.

Key words: Basidiomycetes, environmental change, Finland, Lapland, Northern Boreal, primeval forest, threatened fungi, timberline

Abstract:  Basidiomycetes, especially the wood-inhabiting fungi, were studied in the Värriö Strict Nature Reserve, the Urho Kekkonen National Park and adjacent areas in Finnish East Lapland, which contain some of the last remnants or primeval, Northern Boreal forest at and near the alpine and polar timberline. The qualitative and quantitative composition of the fungi, as indicated by their fruit body production, was studied in naturally regenerating virgin forests and the area of a fairly recent forest fire, special attention being paid both to species recognized as threatened in Finland and to potentially threatened fungi. The area is also affected by long-distance air pollution from the mining and metal industry in the western Murmansk Region, Russia. The main woody plants decayed by basidiomycetes in the region are Pinus sylvestris L., Picea abies (L.) Karsten subsp. obovata (Ledeb.) Domin and Betula pubescens Ehrh. subsp. czerepanovii (Orlova) Hämet-Ahti. A general biogeographical and ecological outline of the study area is presented.

Key words: Aphyllophorales, Corticiaceae, distribution

Abstract:  Twenty-seven new, rare or little collected species of the Aphyllophorales, mainly Corticiaceae, are reported from Finland. The following species are new to Finland: Ceratobasidium pseudocornigerum M.P. Christ., Confertobasidium olivaceoalbum (Bourd. & Galz.) Jül., Hypochnicium erikssonii Hallenb. & Hjortst., H. subrigescens Boid., Litscluluerella clematitis (Bourd. & Galz.) J. Erikss. & Ryv., Phlebiella lloydii (Liberta) Hjortst. & Larsson, Sistotrema heteronemum (J. Erikss.) Strid, Sistotremella perpusilla Hjortst., Tubulicrinis globisporus Larsson & Hjortst. and T. strangulatus Larsson & Hjortst. Information on the distribution is included for some species in the genera Asterostroma, Botryobasidium, Hyphoderma, Hyphodontia, Hyphodontiella, Hypochniciellum, Jaapia, Kavinia, Lobulicium, Phlebiella, Sistotremastrum, Steccherinum, Trechispora and Tubulicrinis. Drawings of 21 species are presented.

Key words: Distribution, Fennoscandia, Lactarius bertillonii, Lactarius vellereus, taxonomy

Abstract:  The taxonomic status of Lactarius vellereus (Fr.: Fr.) Fr. and L. bertillonii (Neuh. ex Z. Schaefer) M. Bon as separate species is substantiated, their distribution in Fennoscandia and Denmark is mapped, and their ecology and relationships are discussed. In the northem temperate zone, L. vellereus is fairly common in broad-leaved forests in Denmark, southernmost Sweden and westernmost Norway. In the hemiboreal zone, it is rarer and concentrated near the coast. L. bertillonii is restricted to broad-leaved or mixed forests in the hemiboreal zone and the southern part of the southern boreal zone. Agaricus vellereus Fr. is neotypified.

Key words: Aromatic lichen substances, Cladonia luteoalba, lichen, taxonomy

Abstract:  The taxonomic status and podetial morphology of Cladonia luteoalba A. Wilson & Wheldon have been re-examined. The species commonly grows on podetia of other related lichens, in particular C. coccifera (L.) Willd., C. borealis Stenroos and C. metacorallifera Asah., with which it is apparently able to form commensalistic symbioses. Its true podetia are escyphose, decorticate, rudimentary structures, never found with hymenia. Earlier, the podetia of the host lichens have been misinterpreted as podetia of C. luteoalba. The species comprises four major chemotypes: (1) the zeorin strain, (2) the barbatic acid strain, (3) the squamatic acid strain, and ( 4) the fumarprotocetraric acid strain. The distribution of the major chemotypes is mapped. The species is reported as new to Japan, China, India, Idaho and S. Finland.

Key words: Agaricales, Basidiomycetes, NW Europe, Picea abies, Russula olivina, R. postiana, R. taigarum, taxonomy

Key words:  Two new species are described from Fennoscandia, Russula olivina Ruotsalainen & Vauras and Russula taigarum Ruotsalainen & Vauras. Both are boreal fungi growing in moist rich forests with Picea abies, and characterized by their mild taste, and pileipellis with dermatocystidia and without encrusted elements. Further characteristics for R. olivina are the greenish pileus, 2-spored basidia and large spores with isolated spines, while R. taigarum has a matt brown-red pileus and stipe with unevenly distributed red colour. R. postiana Romell is lectotypified.

Key words: Acaulospora, Endogonaceae, Glomus, occurence in Poland, taxonomy

Abstract: The Polish occurrence and distribution are described and illustrated for five species of the Endogonaceae. Glomus fasciculatum (Thaxter) Gercl. & Trappe emend. Walker & Koske has frequent occurrences throughout the country. Glomus aggregatum Schenck & Smith emend. Koske, G. etunicatum Becker & Geed. and G. occultum Walker probably occur in the whole of Poland as well, although with lower frequencies. All four species were found among both cultivated and natural plants. Acaulospora rugosa Morton was isolated from only 1 of the 152 soil samples studied. The species is new to Europe, having earlier been known only from West Virginia.
