 Description: Macroscopic characters: Basidiocarps resupinate, widely effused, adnate, 2–4.5 × 5–12 cm, 100–260 μm thick, membranaceous, even or minutely granular, not cracked, white, pale pink-ish buff to margerite yellow or cream color, not changing color in 5% KOH; margins thinning out, pruinose, concolorous; spines if present, conical, narrowly fimbriate at slender apex, in which a single or several cystidia are occupied (see fig. 14G), 70 μm wide, 130 μm high. Microscopic characters: Basal layer of context 25–37 μm thick, separable from substrata, composed of densely parallel thick-walled hyphae; intermediate layer of context 30–180 μm thick, composed of vertically densely interwoven hyphae; often in 2 to 3 layers; hyphae at basal layer with wall 1.5–2 μm thick, 5 μm wide, with clamp connections, hyphae at inter-mediate layer thin-walled, smooth, with abundant clamp connections, frequently irregularly turgid, 3.5–10 μm wide; cystidia rare, cylindrical, finely encrusted, aseptate, with wall 2–3 μm thick, thinner towards apex, sometimes enmeshed in the sterile hyphal sheath, protrud-ing, smooth at apex, protruding 40–100 μm high, 7–9 μm wide, while the hyphae of the sheath smooth, thin-walled, cylindrical, flexuous, containing oil drops, easily stained by phloxine, rounded or obtuse at apex, 10–12×23–37 μm, densely and compactly embedded among context; basidia clavate or ventricose, 10×18–38 μm, with 2–(4) basidiospores; sterigmata curved, 10 μm long, 3 μm wide at base; paraphyses capitate, more or less moniliform, nodding; basidiospores subglobose, globose, elliptical to obovate, thin-walled to thick-walled, with walls to 2 μm thick, 11–12.5 × 8.7–12.5 μm, frequently embedded, smooth, 1-guttulate, non-amyloid. This species is characterized by its having dumbell-shaped basidia, large sterigmata, the gloeocystidia which are very similar to paraphyses and the thick-walled hyphae presented in subiculum.
