Type studies on four Entoloma species from South China

The types of Entoloma caespitosum, E. carneobrunneum, E. metuloideum, and E. pseudogriseoalbum from South China were studied. Entoloma carneobrunneum and E. caespitosum are shown to be conspecific, E. pseudogriseoalbum is revised based on re-examination of the holotype and additional material, and E. metuloideum is referred to Inocybe but requires further study to establish its relationships with other species in that genus.
