Three new wood-decaying polypores from China, Antrodiella lactea, A. nanospora and Frantisekia abieticola, are described and illustrated using morphological characteristics and rDNA internal transcribed spacer (ITS) and large subunit (LSU) sequences. Phylogenetic analyses of the generated sequences, along with those retrieved from GenBank, confirmed the polyphyly of the genus Antrodiella. The Antrodiella s.s. clade includes A. citrinella, A. faginea, A. hoehnelii, A. ichnusana, A. lactea, A. micra, A. nanospora, A. onychoides, A. pallasii, A. pallescens, A. parasitica, A. romellii, A. semisupina and A. stipitata. Antrodiella albocinnamomea and A. zonata grouped with Cerrena unicolour in the Cerrena clade, and they are transferred to Cerrena, as C. albocinnamomea and C. zonata were proposed. The main morphological characters of the genus Antrodiella s.s., and discriminating characters of the new species and the closely related species are discussed.
