Remarks (public):Sarcodontia agrees in some respects with Radulodon (shape of basidia and spores, presence of clamps, thickness of spore wall) but differs in the nature of the subicular hyphae and in the presence of yellow pigment. This does not turn red in KOH as it does in e.g. Mycoacia uda. The genus was by Nikolajeva (1961 p. 174- ) joined with Mycoacia, but from this genus it is well distinguished, e.g. by the nature of the basal hyphae and by the thickened spore wall. Thus, Sarcodontia seems to be monotypic.
The term monomitic does literally mean one kind of hyphae, which is not in the case of Sarcodontia as there are really two kinds, the thin-walled and the thick-walled ones. It is, however, not dimitic in the original sense. The terminology does not always cover the reality as to the nature of the hyphae.
