Two new species of Hymenochaetaceae, Inonotus casuarinae and Phellinus austrosinensis, are described from southern China on the basis of morphological and molecular characters. Phylogenetic analysis based on the large subunit of nuclear ribosomal RNA gene region indicated that the two new species were nested within the Inonotus clade and Phellinus clade, respectively. Inonotus casuarinae is characterized by annual growth habit, a monomitic hyphal structure, presence of both setal hyphae and hooked hymenial setae, and hyaline to pale yellowish basidiospores. Phellinus austrosinensis is characterized by perennial and resupinate basidiocarps, cinnamon surface, presence of hymenial setae, and small hyaline oblong-ellipsoid basidiospores.
