Abstract
Phylogenetic and morphological analyses on Spongipellis and its micromorphological similar genera, Irpiciporus, Pseudospongipellis, and Radulodon, were carried out. Phylogenies on Spongipellis are reconstructed with multiple loci DNA sequences including the internal transcribed spacer (ITS) regions, the large subunit (nLSU), and the small subunit (nSSU) of nuclear ribosomal RNA gene and the translation elongation factor 1-α gene (TEF1). The results demonstrate the polyphyly of Spongipellis, including two genera nested in the different family clades. Pseudospongipellis gen. nov. is established including three new combinations. Three new species, Irpiciporus sinuosus, Radulodon yunnanensis, and Spongipellis quercicola spp. nov., are described and illustrated. A key to the Spongipellis and its micromorphological similar genera is provided.
