Remarks (public):Radulodon reminds in its outer appearance and in the nature of hyphae and basidia of Hyphoderma, but differs by having the round spores with thickened walls. Besides the species of this genus generally have a smooth hymenium. The spores are similar to those of Hypochnicium, but they are not cyanophilous as in this genus. It reminds also of Sarcodontia but in this genus the subicular hyphae are very thick-walled.
Only one Nordic species, besides one species R. americanus in N. America. A third species, R. casearius (Morg.) Ryv. is referred to the genus but differs in having non-clamped, partly thick-walled hyphae, why its place in the genus seems uncertain.
