Abstract: Two rare, orange to red-veiled species, Cortinarius rubrovioleipes Bendiksen & K. Bendiksen and C. hinnuleoarmillatus Reumaux, are studied morphologically and based on the molecular data (ITS-sequences). The distribution of species in Fennoscandia is mapped, their taxonomy and ecology discussed, and colour photographs provided. C. rubrovioleipes is reported for the first time since the description of the species. Also the relationship to C. boulderensis A.H. Sm. and C. pseudobovinus M. M. Moser & McKnight is discussed. The species are here placed in a new section Boulderenses Niskanen, Liimatainen & Kytöv. Short descriptions of North American C. boulderensis and C. pseudobovinus are provided based on the original descriptions and the type material. The nomenclature of species is confirmed by sequencing the type material.

Abstract: Cortinarius lustrabilis Moënne-Locc. is reported for the first time from Fennoscandia. A description of the species is provided and its ecology and distribution are discussed. The nomenclature is confirmed by sequencing the type material, and the ITS-sequences (rDNA) are compared with those in gene bank and our own sequences to see the relationships of this isolated species.

Key words: Basidiomycota, Hydnum, taxonomy

Abstract: Recent observations revealed large variability in spores between materials collected as Hydnum rufescens Fr. New collections and herbarium specimens indicated that Finnish material can be divided into three entities based on spore characters. One of these, with ellipsoidal spores, was described as new by other workers. This species, Hydnum ellipsosporum Ostrow & Beenken, is not rare in Finland. In Finnish populations of H. rufescens s.str. spores are typically globose. Populations with intermixed broadly elliptical spores are more rare. Spore size inH. rufescens is clearly smaller than in H. umbilicatum Peck, in which spores are uniformly globose. A study of the holotype showed spore characters identical to the Finnish material. Hence, H. umbilicatum is claimed to be part of typical European mycoflora; it seems to be fairly common in Finland. Observations made so far indicate that macromorphology and colours may be too variable for a definitive identification in the field. Some possibly helpful, mainly hymenial, characters are discussed. Two collections of H. rufescens are reported from Canada. Colour photographs of all the discussed taxa are provided.

Abstract: Four rare species of aphyllophoroid fungi (Basidiomycota) from Samara Region (European Russia) are described, illustrated and discussed. A new species,Radulomyces arborifer Malysheva & Zmitr., belonging to the R. molaris complex, is described. The new combination, Basidioradulum syringae (E. Langer) Malysheva & Zmitr. is proposed. Pilatoporus epileucinus (Pilát) Kotl. & Pouzar is reported for the first time in Russia. Species keys for raduloid Hyphodermataceae as well as thePilatoporus ibericus complex are given.

Abstract: The rare or overlooked Galerina species G. pruinatipes A.H. Sm. is reported as new for northern Europe with two finds from Finland. The species is previously known only from rotting coniferous wood while the specimens of the two Finnish finds were growing on rotting wood of Alnus and Betula.
