Basidiome at first hypochnoid, becoming continuous, at first even, then covered with distant, blunt, completely fertile warts (not odontioid). Hyphae hyaline, thin- to slightly thick-walled, 1.5-3 µm wide, with small, but abruptly curved clamps (Hyphodontia-type). Basal hyphae sometimes with swellings. Cystidia clavate to capitate, 20-35 X 4-5 µm, often with scattered crystals; some capitate cystidia are hyphoid (2-2.5 µm wide) below the terminal swelling, which is up to 5 µm diam. Basidia suburniform, 12-18 X 4-5 µm. Spores hyaline, slightly thick-walled, globose to subglobose, 4.5-5.5 µm diam., echinulate, cyanophilous, not amyloid, with oil droplet and small apiculus.

The species belongs to Rogersella Liberta & Navas (1978) and the name is an earlier synonym of Rogersella aspera Liberta & Navas. Apart from the ornamented spores and the lower warts, the species resembles Grandinia aspera (Fr.) Julich in many respects. Rogersella is, like Lagarobasidium Rilich, a satellite genus of Grandinia Fr. (= Kneiffiella P. Karst. =Hyphodontia J. Erikss.).
