Aurantiporus Alborubescens (basidiomycota, Polyporales) - First Record in the Carpathians and Notes on Its Systematic Position.

The authors present the first collection of the rare old-growth forest polypore Aurantiporus alborubescens in the Carpathians, supported by a description of macro- and microscopic features. Its European distribution and ecological demands are discussed. LSU rDNA sequences of the collected material were also analysed and compared with those of A. fissilis and A. croceus as well as some other polyporoid and corticioid species, in order to resolve the phylogenetic placement of the studied species. Based on the results of the molecular analysis, the homogeneity of the genus Aurantiporus Murrill in the sense of Jahn is questioned.
