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.

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: Two new genera of polypores (Basidiomycota) are described, Erastia Niemelä & Kinnunen, and Rhodonia Niemelä & K.H. Larsson. The following new combinations are presented: Antrodiella canadensis (Overh.) Niemelä, Erastia salmonicolor (Berk. & M.A. Curtis) Niemelä & Kinnunen, Oligoporus balsaminus(Niemelä & Y.C. Dai) Niemelä, Oligoporus immitis (Peck) Niemelä, Oligoporus persicinus (Niemelä & Y.C. Dai) Niemelä, Porodaedalea laricis (Jacz. ex Pilát) Niemelä, and Rhodonia placenta (Fr.) Niemelä, K.H. Larsson & Schigel. Porodaedalea niemelaei M. Fischer is considered to be synonymous with P. laricis, and Sarcoporia polyspora P. Karst. was found to be an older name for the species commonly known as Parmastomyces transmutans (Overh.) Ryvarden & Gilb. or P. mollissimus(Maire) Pouzar.

Abstract: The polypore genus Ceriporiopsis is revised, and a new combination is proposed:Ceriporiopsis pseudogilvescens (Pilát) Niemelä & Kinnunen. It is the correct name for the species commonly known as C. resinascens (Romell) Doma?ski; the latter is a northerly taxon with narrower spores and less resinous basidiocarp. Also the related C. aneirina (Sommerf.) Doma?ski, C. balaenae Niemelä, C. gilvescens (Bres.) Doma?ski, C. albonigrescens Núñez, Parmasto & Ryvarden and C. cremea (Parmasto) Ryvarden are discussed and compared. The results are supplemented with an extensive list of spore size measurements and by a key to the species.

Key words: Aphyllophorales, Oligoporus, polyporaceous fungi, Postia hibernica, taxonomy

Abstract: The taxonomy of the Oligoporus hibernicus (Berk. & Broome) Gilb. & Ryvarden complex (Basidiomycota) is revised. The study is based on extensive herbarium material chiefly from northwestern Europe and the type material of the taxa involved. The examination of the type of Polyporus hibernicus Berk. & Broome revealed that the name has been misapplied. The name belongs to a taxon, which often has pale yellow basidiocarps and was often erroneously called Physisporus flavicans P. Karst. or Poria johnstonii Murrill, and recently described as Oligoporus septentrionalis Vampola. The name O. parvus Renvall is proposed for the species that has erroneously been called as O. hibernicus in northwestern Europe. Four morphologically very similar species are recognized in the O. hibernicus complex in Europe: O. hibernicus sensu typi, O. perdelicatus (Murrill) Gilb. & Ryvarden, O. simanii (Pilát) Bernicchia, and the new species O. parvus, which is reported from Finland, Norway and Sweden. O. perdelicatus has been collected from seven localities in eastern Finland and is here reported as new to Europe. The species are described and discussed in detail.

Abstract: A new species Junghuhnia vitellina Spirin is described, growing on Betula mandshurica in Russian Far East. Cinereomyces lenis (P. Karst.) Spirin, comb. nova is a so-called kelo fungus; its closest relative C. vulgaris (Fr.) Spirin, comb. nova has relatively wide set of hosts. The latter is new to Russia. Eleven species of Skeletocutis are discussed, and some data on their ecology are treated. S. chrysella Niemelä, S. subincarnata (Peck) Jean Keller and S. stellae (Pilát) Jean Keller are rare taiga species, growing on large spruce or pine trunks at late stages of wood-decomposition. S. biguttulata (Romell) Niemelä and S. brevispora Niemelä are locally common and found in both southern and northern parts of the study area. S. carneogrisea David and S. kuehneri David grow in association with Trichaptum species in virgin as well as managed coniferous forests. S. albocremea David is very rare; it was collected only once in old pine forest. S. kuehneri and S. papyracea David are new to Belarus.

Key words: Agaricales, Bolbitiaceae, Conocybe, Mycoflora of Finland

Abstract: In all 56 taxa of the genus Conocybe are presented from Finland. One variety,Conocybe hornana var. subcylindrospora, is described as new. Besides, C. ambigua, C. anthracophila, C. bispora, C. dumetorum var. dumetorum, C. echinata, C. farinacea, C. fimetaria, C. fuscimarginata, C. gigasperma, C. graminis, C. hexagonospora, C. hornana, C. intrusa, C. juniana var. subsejuncta, C. lenticulospora, C. microspora, C. moseri, C. pallidospora, C. pilosella, C. pseudocrispa, C. singeriana, C. subalpina, C. subovalis, C. subpallida, C. tuxlaensis, C. umbonata, and C. watlingii have not been recorded from Finland earlier. Nearby half of the presented taxa have been found only in the southern part of the country, but the collecting has been occasional, and most species of the genus occur in wide areas also elsewhere. The ecology of the genus show a broad scale, as well. The species of the genus are considered to be saprobes mainly growing in humus, seldom and occasionally on woody substrate (C. gigasperma, C. incarnata). Some species, such as C. farinacea, C. fimetaria, C. fuscimarginata, C. lenticulospora, C. pubescens, C. rickenii, C. singeriana, and C. watlingiigrow often on dung, but also C. albipes, C. juniana, and C. subovalis prefer habitats rich in nitrogen. C. brachypodii, C. juniana var. subsejuncta, C. pilosella, C. rickeniana, and C. subpubescens were found usually in forest or parks, the main part of the habitats of the collects being meadows and pastures. Several species, such as C. apala and C. tuxlaensis, seem to favour calcareous ground. A few finds (C. anthracophila, C. macrocephala, C. pallidospora, C. siliginea) are from burnt ground, but they can grow elsewhere, too. C. umbonata is a species found growing in glass houses exclusively.

Phenologically, the Conocybe species are rather uniform, e.g. C. hornana, C. pubescens, C. rickeniana, C. sienophylla, and Conocybe spec. I we have been found fruiting in Finland from June to October, C. anthracophila, C. brachypodii, C. fimetaria, C. mesospora, and C. subalpina from August to late autumn.

Insgesamt werden 56 Taxa aus Finnland vorgestellt. Eine Varietät, Conocybe hornana var. subcylindrospora, wird als neu beschrieben. Weiters werden C. ambigua, C. anthracophila, C. bispora, C. dumetorum var. dumetorum, C. echinata, C. farinacea, C. fimetaria, C. fuscimarginata, C. gigasperma, C. graminis, C. hexagonospora, C. hornana, C. intrusa, C. juniana var. subsejuncta, C. lenticulospora, C. microspora, C. moseri, C. pallidospora, C. pilosella, C. pseudocrispa, C. singeriana, C. subalpina, C. subpallida, C. tuxlaensis, C. umbonata und C. watlingii erstmals aus Finnland nachgewiesen. Beinahe die Hälfte der vorgestellten Taxa wurde nur im Süden Finnlands gefunden. Es ist aber nicht angebracht, daraus irgendwelche Verbreitungsmuster abzuleiten, da die Auswahl der Sammelgebiete rein zufällig war und die meisten Arten auch anderswo weit verbreitet vorkommen. Auch die Ökologie der Gattung zeigt eine weite Variationsbreite. Die Vertreter der Gattung Conocybewerden zu den Saproben gezählt, die im Humus, selten und nur gelegentlich auf Holz (C. gigasperma, C. incarnata) wachsen. Einige Arten, wie C. farinacea, C. fimetaria, C. fuscimarginata, C. lenticulospora, C. pubescens, C. rickenii, C. singeriana undC. watlingii, wachsen bevorzugt auf Dung oder Mist, aber auch C. albipes, C. junianaund C. subovalis lieben stickstoffreiche Habitate. C. brachypodii, C. juniana var.subsejuncta, C. pilosella, C. rickeniana und C. subpubescens warden gewöhnlich in Wäldern und Parks angetroffen, aber die meisten Vertreter der Gattung bevorzugen Weiden und Wiesen. Manche Arten, wie C. apala und C. tuxlaensis, scheinen Kalkböden zu bevorzugen. Einige wenige Funde (C. anthracophila, C. macrocephala, C. pallidospora, C. siliginea) wurden auf Brandstellen gemacht, sie können aber auch an anderen Standorten wachsen. C. umbonata wurde bisher ausschließlich in Gewächshäusern nachgewiesen.

Die Phenologie der Vertreter der Gattung Conocybe ist ziemlich einförmig, so wurden z. B. C. hornana, C. pubescens, C. rickeniana, C. sienophylla und Conocybe spec. I in der Periode von Juni bis Oktober, C. anthracophila, C. brachypodii, C. fimetaria, C. mesospora und C. subalpina von August bis zum Spätherbst gesammelt.
