In the present paper, three additional species of Entoloma subgenus Pouzarella viz. E. erectoides, E. griseocarpum and E. rubropilosum are described from China. E. rubropilosum is a typical species in section Pouzarella; E. griseocarpum and E. erectoides are members of sect. Dysthales. The taxa are further confirmed by ITS, RPB2, LSU and mtSSU analyses and phylogenetic relationships with other Entoloma subgen. Pouzarella species are also discussed. ITS sequence analysis showed that the sizes of the entire ITS region and ITS1 are remarkably divergent, while the ITS2 is conserved in length within Entoloma subgen. Pouzarella. Molecular analyses, based on the combined dataset, demonstrated that species diversity of subgen. Pouzarella in China is much higher than previously thought, in the present study twenty phylogenetic species from China are taken into consideration. On the other hand, morphological and molecular analyses suggested that classification of Entoloma subgen. Pouzarella probably has to be fundamentally re-adjusted based on additional data.
