Description:Aleurodiscus oakesii (Berk. & M.A. Curtis) Pat.
Rev. Mycol. 12: 133, 1890. - Corticium oakesii Berk. & M.A. Curtis, Grevillea 1: 166, 1873. - Aleurodiscus oakesii (Berk. & M.A. Curtis) Cooke, Grevillea 3: 172, 1875, invalid name as the generic name was not yet published.
Basidiocarp first cupulate, 1.5-5.5 mm diam., up to 0.6 mm thick, later more effused and stereoid, margin reflexed to deflexed on drying, farmose to subcoriaceous, hymenophore smooth, pale cream, drying avellaneous to ochraceous, sometimes with pale grey tints, abhymenial surface floccose, white when fresh, drying pale ochraceous.
Hyphal system monomitic, generative hyphae simple-septate, in the hymenium and subhymenium thin-walled to slightly thick-walled with many septa, richly branched, 3-5 µm wide, in the subiculum and on the abhymenial surface sparingly dichotomously branched, smooth with few clamps only at the branching, 3-7 µm wide. These hyphae have sometimes been cited (Lemke) as skeletal hyphae. Acanthophyses numerous, filiform to subclavate, slightly thick-walled, 40-80 x 4-6 µm, usually with apical antler-like protuberances, some also with lateral protuberances. Gloeocystidia moniliform-cylindric to mammillate, smooth, up to 80 µm long and 10 µm diam., embedded, yellowish in KOH, sometimes a few protuberances can be observed close to the apex. Basidia flexuous-subclavate, 75-120 x 12-15.5(20) µm, with 4 sterigmata. Basidiospores ovoid-ellipsoid, 18-27 x 12-14(-17) µm, thick-walled at maturity, finely warted.
