The new genus Frantisekia Spirin et Zmitr. is described, and three species are included in it-Frantisekia fissiliformis (Pilát) Spirin et Zmitr. comb. nov. (type of the genus), Frantisekia mentschulensis (Pilát ex Pilát) Spirin comb. nov., and Frantisekia ussurii (Y. C. Dai et Niemelä) Spirin comb. nov. These species are described, and their identity, ecology and distribution are briefly discussed. Tyromyces aurantiacus (Komarova) Komarova is regarded to be a synonym of Frantisekia mentschulensis.
Anomoloma albolutescens (Romell) Niemelä & K.H. Larss. is found for the fi rst time in European Russia. Ecology and distribution of this species are briefl y reviewed. Poria buxi Bondartsev is a later synonym of Hyphodontia fl avipora (Cooke) Sheng H. Wu. Hyphodontia radula (Schrad. : Fr.) E. Langer & Vesterholt was found to be widely distributed in hemiboreal European Russia. Lindtneria trachyspora (Bourdot & Galzin) Pilát and Sistotrema dennisii Malençon are reported as new to Russia. Sistotrema brunneolum Spirin & Zmitr. is described as a new species closely related to S. alboluteum (Bourdot & Galzin) Bondartsev & Singer. The new species is characterized by relatively fi rm, brownish, porioid basidiocarps, two-or four-sterigmate basidia, and short-cylindrical to ellipsoid, thick-walled spores. The isolated position of both S. brunneolum and S. alboluteum within the genus Sistotrema is discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
