Description:Radulodon Ryvarden, Can. J. Bot. 50: 2073, 1972.
Basidiome resupinate, effused, adnate, hymenophore hydnoid, with usually long cylindrical or flattened aculei. Subiculum pale, mainly thin. Hyphal system monomitic, hyphae thin-walled or with a slight thickened walls, all hyphae with clamps. Cystidia lacking or present, thin-walled, more or less tubular. Basidia clavate, with 4-sterigmata and a basal clamp. Basidiospores globose to subglobose, smooth, moderately thick-walled, rarely thin-walled, inamyloid, indextrinoid, acyanophilous.
Remarks: Radulodon differs from related genera such as Hyphoderma in its globose thick-walled basidiospores; from other hydnoid species of Phanerochaete it is distinguished also by the presence of clamped generative hyphae. It is molecularly classified in the Meruliaceae (Larsson 2007b).
