The first records of Lindtneria pterospora (Stephanosporaceae, Basidiomycota) in Russia
Abstract
The rare species, Lindtneria pterospora Reid (Stephanosporaceae, Basidiomycota) was recorded from the territory of Russia for the first time. It was found on the alvared in the complex natural monument «Dontso» in the Leningrad Region (59°26'29.4'' N, 29°45'50.7'' E) from European part of Russia and in «Kedrovaya Pad'» reserve from Russia Far East. Species description based on collected material is provided.
A synopsis of Lindtneria is proposed, mainly based on a critical compilation of the literature. It contains a discussion on the relationships between the genera Lindtneria, Mycolindtneria, Cyanobasidium, Cyanohypha and Botryohypochnus and on the position of the genus Lindtneria in the systematics. The main characters of Lindtneria are listed. Then nomenclature and diagnostic characters are given for each species of the genus. An identification key is proposed (with English translation).
The relationship between Lindtneria trachyspora, with resupinoid basidiomes, and Stephanospora caroticolor, with sequestrate basidiomes, is discussed. Analyses of the ITS1, ITS2 and 5.8 S ribosomal DNA sequences confirm the morphological and chemical affinities established by early authors. Key words—Stereales, Russulales, Stephanosporaceae, Lindtneriaceae, rDNA
