Dendrocorticiopsis Sheng H. Wu, C.L. Wei & S.H. He gen. nov.

Diagnosis.

Dendrocorticiopsis differs from other genera by having strictly resupinate basidiomata, ivory hymenphore, a compact texture, a monomitic hyphal system, nodose-septate hyphae, encrusted cystidia, dendrohyphidia and ellipsoid to ovoid basidiospores.

Description.

Basidiomata resupinate, effused, adnate, membranaceous. Hymenial surface brownish ivory, grayish ivory to lilac ivory, smooth. Hyphal system monomitic; generative hyphae nodose-septate, colorless, slightly thick- to thick-walled. Subiculum uniform, with compact texture, usually with crystal masses; hyphae fairly horizontal. Hymenial layer thickening, with compact texture, usually with oily materials, hyphae more or less vertical. Dendrohyphidia numerous, thick-walled toward base, colorless. Cystidia clavate, apically with resinous materials. Basidia clavate to subclavate, 4-sterigmata, thick-walled toward base. Basidiospores ellipsoid to ovoid, sometimes broadly ellipsoid, smooth, thin-walled or occasionally slightly thick-walled, negative in Melzer’s reagent, acyanophilous.
