　Description： Basidiocarp effuse, ± adnate, subceraceous, 40-110 µm thick in section. Hymenial surface white, smooth, rarely cracked; margin white, thinning, pruinose. Hyphal system monomitic; hyphae nodose-septate. Subiculum uniform, composed of basal layer, with compact texture, up to ca. 15 µm thick, sometimes indistinct; hyphae horizontal, colorless, straight, agglutinated, 2.5-4.5 µm diam., thin- or slightly thick-walled. Hymenial layer with dense texture, thickening; hyphae ± vertical, somewhat interwoven, colorless, ± tortuous, rather agglutinated, 2-4 µm diam., thin-walled. Crystal masses common in subiculum and adjacent subhymenium. Cystidia variably abundant, immersed or projecting, apically covered with yellowish brown resinous material, cylindrical or subclavate, 25-70 × 7-12 µm, thin- or slightly thick-walled. Basidia subutriform, 23-30 × 6-8 µm, with four large sterigmata. Basidiospores allantoid or suballantoid, smooth, thin-walled, with oil-drops, (10-) 10.5-13.5 (-14.5) × 3.7-4.5 µm, IKI-, CB-.
