Taxonomy and phylogeny of Sidera (Hymenochaetales, Basidiomycota): four new species and keys to species of the genus.

ABSTRACT: Sidera is a polypore genus with white to cream or buff basidiomata, whose species in Hymenochaetales are poorly known. We study the phylogeny and diversity of Sidera based on our recent collections from tropic and subtropic Asian-Pacific regions. Phylogenetic analyses based on the internal transcribed spacer (ITS) and nuclear large subunit (nLSU) ribosomal RNA gene regions indicate that ten terminal lineages are well supported within Sidera. Based on morphological examination and phylogeny, four new species, viz. Sidera minutissima, S. parallela, S. srilankensis and S. tenuis are described, and a new combination, Sidera minutipora, is proposed. All these species are illustrated. Sidera minutissima is characterized by tiny basid
