Description:Gloeodontia Boidin, Cahiers de La Maboké 4: 22, 1966.
Type species: Irpex discolor Berk. & M.A. Curtis, Grevillea 1(3): 45, 1872.
Basidiome resupinate, effused, adnate, hymenophore hydnoid, subiculum well developed. Hyphal system monomitic or dimitic, generative hyphae with clamps, thin-walled or with slight thickened walls, skeletal hyphae rarely branched, aseptate or with rare septa, thick-walled. Cystidia (pseudocystidia) arising in tooth trama, cylindrical, heavily encrusted with hyaline crystals. Gloeocystidia scattered in tooth trama, frequent in hymenium, blue to blue-black in sulfuric benzaldehyde. Basidia cylindrical to urniform, with 4-sterigmata, with a basal clamp. Basidiospores hyaline to pale yellow under the microscope, thick-walled, asperulate, amyloid.
Remarks: Gloeodontia is morphologically defined by the hydnoid hymenophore, gloeocystidia, encrusted pseudocystidia, and by the amyloid asperulate basidiospores. Gloeodontia forms a well definited group within the russuloid lineage (Larsson 2007b).
