A new species, Paraxerula ellipsospora, is described from southwestern China using both morphological and molecular phylogenetic evidence. This species differs phenotypically from the three known species in the genus by its greyish colored pileus, ellipsoid to elongate basidiospores, and a distribution in pine forests in Yunnan. Geographical divergences of Paraxerula in the Holarctic were observed. All species show continental endemisms, yet related species occurring in East Asia and in Europe, or in East Asia and in North America were found.
