Abstract

Favolus is a natural genus that is closely related to Polyporus. A taxonomic study of Favolus was carried out based on morphological characteristics and phylogenetic analysis of the internal transcribed spacer (ITS) region (ITS1-5.8S-ITS2 = ITS) and 18S and 28S genes of the nuc rDNA, translation elongation factor 1-α gene (TEF1-α), the mt 16S rDNA gene (mt rrnS), β-tubulin gene (TBB1), and the RNA polymerase II largest subunit (RPB1) and second largest subunit (RPB2) genes. Fourteen specimens collected from subtropical to tropical regions in China were shown to be different from existing Favolus species. They are described and illustrated here as four new species, namely, Favolus niveus, F. septatus, F. pseudoemerici, and F. subtropicus.

Keywords: Favolus; Polyporus; morphology; phylogeny; wood-rotting fungi.
