　Description： Basidiocarp at first forming orbicular patches, then effuse, adnate, ceraceous, 70-250 µm thick in section. Hymenial surface Chamois, slightly tuberculate, cracked extensively and exposing white filamentose subiculum and the substratum; margin Ivory Yellow, thinning, slightly byssoid. Hyphal system monomitic; hyphae nodose-septate. Subiculum uniform, composed of medullary layer, with rather dense to dense texture; hyphae ±horizontal next to substratum, fairly vertical near subhymenium, colorless, rather distinct, slightly tibiiform, sometimes rather short-septate, 2.5-5.5 µm diam., thin-walled near subhymenium, slightly thick-walled near substratum. Hymenial layer with compact texture, ±thickening; hyphae vertical, colorless, ± agglutinated, narrower than those of subiculum, thin-walled. Yellowish brown excreted material common throughout section. Cystidia numerous, projecting for ap-proximately half their lengths, cylindrical, with narrow apices and bases, 35-65 × 4.5-8.5 µm, thin- or slightly thick-walled. Basidia subclavate, 18-25 × 4.7-5.3 µm, 4-sterigmate. Basidiospores ellipsoid, or narrowly ellipsoid, adaxially flattened, usually tapering towards apiculus, (4.8-) 5.2-6 (-6.3) × 2-2.5 µm, IKI-, CB-.
