gen. et sp. nov. and sp. nov. (, ) from East Asia.

, a small and under-studied family of , includes mostly saprophytic taxa with varied basidiomes. In this study, we focus on wood-decay species with corticioid or stereoid basidiomes. Phylogenetic analyses of concatenated - sequences uncovered seven generic lineages of corticioid or stereoid fungi-, , , , , , and gen. nov. The genus is shown to be in the family, and two new species, and , are described from East Asia. Morphologically, . is characterized by resupinate basidiomes with smooth hymenophores, a dimitic hyphal system with clamped generative hyphae and micro-binding hyphae, cystidia with resinous-like or golden yellow contents, and ellipsoid basidiospores. is monotypic, differing from by a trimitic hyphal system of clamped generative, micro-binding, and brown, thick-walled skeletal-like hyphae, clavate to cylindrical cystidia with homogenous, colorless contents, and hyphidia. Descriptions and illustrations are provided for the new taxa and , and a key to corticioid or stereoid genera in is included.
