 Description: Basidiocarp effuse, adnate, membranaceous, 35-120 μm thick in section. Hymenial surface white, smooth, rarely cracked; margin concolorous, thinning, pruinose. Hyphal system monomitic; hyphae nodose-septate. Subiculum uniform, composed of medullary layer, rather loose near substratum, fairly dense next to hymenial layer; hyphae fairly vertical, moderately ramified, colorless, ± distinct, 1.8-3.3 μm diam., with 0.3-0.9 μm thick walls. Hymenial layer with dense texture; hyphae colorless, narrower than those of subiculum. Cystidia numerous, projecting for approximately half their lengths, capitate, 25-45 × 3-4.5 μm, thin-walled. Basidia clavate, 15-22 × 3.5-4.5 μm, 4-sterigmate. Basidiospores allantoid, thin-walled, 5.5-7 × 1.2-1.5 μm, IKI-, CB-.
