Hydnophanerochaete odontoidea (Sheng H. Wu) Sheng H. Wu & C.C. Chen 2018, in Chen, et al., MycoKeys 39, 75 96 (2018)

Basionym: Phanerochaete odontoidea Sheng H. Wu, Botanical Bulletin of the Academia Sinica 41: 169 (2000)

Diagnosis: Basidiocarps annual, effused, adnate, ceraceous, somewhat brittle, 50200 μm thick in section (aculei excluded). Hymenial surface initially buff, with age turning ochraceous to pale brown, no colour changes in KOH, tuberculate to grandinioid when young, becoming odontioid to hydnoid with age, extensively cracked; margin paler to whitish, fairly determinate. Aculei conical to cylindrical, usually separate, with obtuse to acute apex, 14 per mm, up to 100700 × 100250 μmHyphal system basically monomitic, some specimens with quasi-binding hyphae near substratum; generative hyphae simple-septate. Subiculum fairly uniform, composed of a basal layer of compact texture; generative hyphae mainly horizontal, colourless, 46 μm diam., with 0.81 µm thick walls; quasi-binding hyphae sometimes present near substratum, colourless, 13 µm diam. Hymenial layer thickening, with compact texture, generative hyphae somewhat vertical, colourless, 36 μm diam., slightly thick-walled. Trama of aculei of compact texture; generative hyphae mainly vertical, other features similar to those in subiculum; crystal masses present near apex. Cystidia lacking, but projecting hyphal ends in the hymenium may be present. Basidia clavate, 1418 × 4.55.5 μm, 4-sterigmate. Basidiospores narrowly ellipsoid to cylindrical, adaxially slightly concave, smooth, thin-walled, homogeneous, inamyloid, non-dextrinoid, acyanophilous, 68.1 × 2.53.3 μm.
