Leucogyrophana (Aphyllophorales): identification of species

Abstract

The basidiocarps of nine species are described and the cultural characters are presented for six species. All have pale yellow spores and hyphae with clamp connections and primarily occur on coniferous wood where they are associated with a brown rot. Leucogyrophana arizonica and L. romellii are proposed as new species. Merulius pulverulenta Fr. is transferred to Leucogyrophana. New synonymy is proposed following the study of type specimens and several names previously regarded as synonyms are shown to apply to distinct species.
