Morphological description

Asexual morph: Basidioma annual, resupinate, adnate, byssoid, without odour and taste when fresh, up to 15 cm long, 3 cm wide, 100–260 µm thick. Hymenial surface smooth to floccose, cream when fresh, cream to slightly buff on drying. Margin sterile, thinning out, narrow, cream. Hyphal system monomitic, generative hyphae with clamps, colourless, thickwalled, frequently branched, interwoven, 2.5–4.5 µm in diameter; IKI-, CB-; tissues unchanged in KOH; subhymenial hyphae densely covered by crystals. Cystidia tubular, encrusted with small crystals, 25–97 × 5.5–9.5 µm. Basidia clavate to subcylindrical, slightly constricted in the middle to somewhat sinuous, with 4 sterigmata and a basal clamp, 20–30 × 4.5–6 µm. Basidiospores ellipsoid, colourless, thin-walled, smooth, IKI-, CB-, (5.5–)6–7.5(– 8) × 3–4.5(–5) µm, L = 6.53 µm, W = 3.71 µm, Q = 1.73–1.79 (n = 60/2).
