 A standard 1995 reference work included within the Botryobasidiaceae the corticioid genera "Botryobasidium", "Botryodontia", "Botryohypochnus" (considered a synonym of "Botryobasidium"), "Candelabrochaete", "Suillosporium", and "Waitea", based mainly on similarities in their basidiocarp micromorphology.The family was placed in the order Stereales.Molecular research, based on cladistic analysis of DNA sequences, has confirmed the Botryobasidiaceae as a separate family, but restricted to the genera "Botryobasidium" and its anamorphs together with "Botryohypochnus" (if distinct).
