Taxonomy of Epithele (Polyporales, Basidiomycota)

Nakasone, K. K. (2013) Taxonomy of Epithele (Polyporales, Basidiomycota).

Sydowia 65 (1): 59–112

Seventeen species are accepted in the genus Epithele, including new species E. belizensis, E. ceracea, E. reunionis, and E. ryvardenii. Descriptions and illustrations are provided for all species. The generic concept is emended to include Corticium bambusae, from Trinidad on bamboo, which lacks sterile hyphal pegs; the new combination Epithele bambusae is proposed. The type specimens of Dendrothele duthieae, D. subfusispora, Epithele macarangae, and Laeticorticium odontioides were examined and determined to be conspecific with E. interrupta. The monotypic genus Skeletohydnum is considered distinct from Epithele, and Tubulicium ramonense is placed in synonymy with Skeletohydnum nikau. A new genus, Myriothele, is proposed for Epithele philippiae, which has urniform basidia and spherical basidiospores. Xenasma macrosporum is transferred to Dextrinocystis. A key to the accepted species of Epithele is presented as well as a preliminary key to the corticioid and polyporoid genera and species with hyphal spines, sterile ridges, and plates.

Keywords: Epithele typhae, epithelioid fungi, Grammothele, hyphal pegs, Mycothele.
