　Description： Basidiocarp forming small patches, ca. 2.5 ×1cm, adnate, membranaceous, 100-350 µm thick in section. Hymenial surface Pale Cinnamon-Pink to Cartridge Buff, no color changes in KOH, smooth, not cracked; margin concolorous, rather abrupt, sometimes slightly fila-mentose. Hyphal system monomitic; most hyphae simpleseptate, a few septa in subiculum with single or double clamp connections. Subiculum uniform, composed of medullary layer, with rather loose texture; hyphae ±horizontal, somewhat vertical near subhymenium, sparsely ramified and loosely interwoven, brownish, distinct, straight, 3.5-7 µm thick diam., with 0.5-0.8 µm thick walls, not encrusted, anastomoses occasional. Hymenial layer with compact texture, somewhat thickening; hyphae vertical, colorless, agglutinated, distinctly narrower than those of subiculum, thin-walled. Cystidia lacking. Basidia subclavate, 18-25 × 4.2-5 µm, 4-sterigmate. Basidiospores ellipsoid, adaxially flattened or slightly concave, smooth, thin-walled, usually with one or two oil-drops, 4.5-5.5 × 2.3-3 µm, IKI-, CB-.
