Reevaluation of Hohenbuehelia nigra and species with close affinities

Specimens tentatively determined as Hohenbuehelia nigra var. microspora were found in the environs of Buenos Aires. Study of collections in BAFC identified by Singer as H. nigra showed that var. microspora differed considerably from var. nigra. This led to a study of the holotypes of H. nigra var. m...
