　Description： Basidiocarp resupinate, effuse, adnate, subceraceous or ceraceous, 50-200 μm thick in section. Hymenial surface light orange, smooth, occasionally cracked; margin usually rather determinate, concolorous or deeper. Hyphal system monomitic; hyphae nodose-septate. Subiculum fairly uniform, composed of basal layer, usually thin, with compact texture; hyphae colorless, mainly horizontal, glued together and indistinct, 2-4 μm diam., thin- or slightly thick-walled. Hymenium thickening, not clearly differentiated from subiculum, with compact texture; hyphae colorless, mainly vertical, indistinct, usually glued together, slightly narrower than those of subiculum, thin- or slightly thick-walled. Gloeocystidia numerous, mostly immersed, tubular or cylindrical, somewhat flexuous, colorless to yellow, 6-12 μm diam., up to ca. 100 μm long, with 0.5-1.5 μm thick walls, SA+. Basida clavate or subclavate, 16-22 × 5-6.5 μm, 4-sterigmate. Basidiospores narrowly ellipsoid, aculeate (smooth in KOH), thin-walled, (6.2-) 6.5-7.5 (-7.7) × 2.8-3.2 μm, IKI bluish black, CB–.
