75475E4CFFF60D7EFF285E95F2A30EE2.taxon	description	Basidiomata: — Annual, resupinate, adnate, punctate, without odor or taste when fresh, soft coriaceous when fresh, becoming hard coriaceous upon drying, up to 5 cm long, 2 cm wide, 50 – 100 µm thick. Hymenial surface grandinioid, white when fresh, white to cream upon drying. Sterile margin white, narrow, up to 0.5 mm wide. Hyphal structure: — Hyphal system monomitic; generative hyphae simple-septa, colorless, thin- to thick-walled, rarely branched, interwoven, 2 – 5.5 µm in diameter; IKI –, CB –; tissues unchanged in KOH; numerous crystals present amongst generative hyphae. Hymenium: — Cystidia and cystidioles absent. Basidia clavate, slightly sinuous or constricted in the middle, with a few granules, 4 sterigmata and a simple septum at the base, 17.5 – 25 × 5 – 7.5 µm; basidioles dominant, similar to basidia in shape, but slightly smaller.
