Studies in Spongipellis sensu stricto (Polyporales, Basidiomycota)

Abstract

Taxonomy of Spongipellis sensu stricto is revised based on morphological studies and DNA data. Here, the genus is accepted as a member of Meripilaceae, and it contains five species. Of them, S. spumea, the generic type, occurs in Europe, two species, S. ambiens (= Tyromyces sibiricus) and S. variispora sp. nov., are found in East Asia, and S. profissilis comb. nov., is reported from Central Europe, Siberia and Far East Asia. The North-American species, S. occidentalis, is reinstated as a separate species and redescribed here based on historical material.
