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.)

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.

Finnish records of the genus Russula. The new species R. olivina and R. taigarum

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.
