Novelties and records of poroid Basidiomycetes in Finland and adjacent Russia

Abstract

Leningrad Region, Russia; this is the second find of the species after its description from Siberia. Junghuhnia fimbriate/la (Peck) RyYarden was found in Leningrad Region; this is the first record in northern Europe. Skeletocutis borealis Niemela and many other rare species are discussed, including new localities from Finland and/or NW Russia. Some of them are illustrated, and many species are supplied w ith detailed spore measurements. 143 polypore species were recorded and collected by the authors and their co-workers in virgin forests of Russian Karelia in wide sense; 12 of them are new to the area.

First record of Skeletocutis ochroalba (Polyporales) in the Czech Republic.

“…Despite its wide geographical range, the species appears to be generally rare in its distribution area and is included in the Red lists of Sweden (VU) (Dahlberg et al 2010) and Norway (DD) (Kĺlĺs et al 2010). It has been collected from dead wood of various spruce species -Picea abies in Europe, P. glauca in N America and P. jezoensis in China (Dai 2000, Niemelä et al 2001, Ryvarden & Gilbertson 1994, but also from Pinus nigra ssp. laricio (Norstedt et al 2001).…”

Records of rare aphyllophoroid fungi on Scots pine in northern Sweden

“…The species was collected in Tjeggelvas Nature Reserve on dry, large and hard logs. It was described from Finnish Lapland (Renvall & Niemelä 1992), and is now also known from several localities in Norway (Renvall & Niemelä 1992), Russia (Niemelä et al 2001, and China (Dai 2000). In Sweden, A. primaeva is very rare (Gärdenfors 2010).…”

“…It has been recorded a few times in Sweden (Johannesson et al 2000, Edman et al 2007) and it seems to be very rare and its distribution strongly continental. A. pallasii is also known from northern parts of Norway and Finland (Ryvarden et al 2003) and from the taiga zone of Russia (Niemelä et al 2001, Kotiranta et al 2005 and from China (Dai 2000). A. pallasii was collected on a hard and thin, moss-covered pine log with dead Trichaptum abietinum (P.…”

New and in North Europe rare polypore species (Basidiomycota) with annual, monomitic basidiocarps

“…Our measurements from French and Finnish specimens imply that David (1980) somewhat overestimated the thickness of the spores ("5-5.5-6 x 2~-tm"); her measurements were probably made in KOH. Spore dimensions and ecology of P. caesia and P. alni Niemela & Vampola were published by Niemela et al (2001).…”
