　Description： Basidiocarp effuse, adnate, membranaceous-crustaceous, fairly brittle, 200-500 μm thick in section. Hymenial surface Pale Pinkish Buff, smooth when young, tuberculate when old, sometimes cracked; margin usually paler, rather determinate, sometimes slightly filamen-tose-byssoid. Hyphal system dimitic; generative hyphae nodos-ese-ptate. Subiculum fairly uniform, composed of medullary layer, with rather dense texture; generative hyphae ± interwoven, colorless or subcolorless, ± tortuous, somewhat agglutinated, 1.2-2.2 μm diam., thin-walled, often covered with scattered yellowish brown resinous material; quasi-binding hyphae yellowish, moderately ramified, 0.8-1.5 μm diam., thin-walled. One brown zone usually present near substratum, full of brownish resinous material. Subhymenium not clearly differentiated. Cystidioles numerous, subulate, having the broadest part near apices, 16-25 × 3-4 μm, thin-walled. Cystidia very numerous, mostly immersed, tubular, with narrow bases, 50-100 × 5.5-8 μm, slightly thick-walled, containing sulpho-negative yellow oil-drops. Basidia clavate, usually with elongated and narrow bases, 18-25 × 4-4.5 μm, 4-sterigmate. Basidiospores ellipsoid, adaxially flattened, with a rather prominent apiculus, smooth, thin-walled, with homogeneous contents, (4.2-) 4.4-5 (-5.3) × 2.5-3 (-3.2) μm, IKI-, CB-.
