Remarks (public):Ceratobasidium is mainly chatacterized by the repetitive basidiospores, the simple-septate hyphae, and the almost globose basidia. It is very close to Thanatephorus and Botryobasidium. The latter genus is distinguished by the absence of spore repetition, and Thanatephorus differs in the basidial and hymenial morphology and structure. In some molecular studies, Binder et al. (2005), Moncalvo et al. (2006) Ceratobasidium is included in the cantharelloid clade forming a monophyletic group with Thanatephorus and very closely related to Botryobasidium.
