Rigidoporus minutus (Polyporaceae, Agaricomycotina, Basidiomycota), is described from eastern China. It is characterized by resupinate basidiocarps, tiny pores, monomitic hyphal system with simple-septate generative hyphae, and by minute, broadly ellipsoid to subglobose, thinwalled basidiospores. In addition, it has mammillate to subulate cystidioles. Rigidoporus cinereus, is new to Chinese fungal flora. Detailed descriptions and illustrations for the two species are supplied, and a key to the Chinese species of Rigidoporus is provided along with a synoptic description of each species.
