　Description： Basidiocarp effuse, ± adnate, submembranaceous or pellicular, 40-200 μm thick in section. Hymenial surface ivory yellow, smooth, rarely cracked; margin paler or white, filamentous or fimbriate. Hyphal system monomitic. Hyphae nodose-septate. Subiculum fairly uniform, composed of medullary layer, with rather loose to moderately dense texture; hyphae ± horizontal, colorless, distinct and fairly straight, 1.5-3.5 μm diam., with thin to slightly thick walls. Subhymenium differentiated from subiculum, thickening, with rather compact texture; hyphae colorless, indistinct, ± agglutinated, narrower that those of subiculum. Cystidia of two kinds : (1) Lamprocystidia numerous, projecting or immersed, sometimes overlapping in subhymenium, colorless, heavily encrusted for approximately apical halves, subulate or conical, 20-65 × 5-10 μm (encrustation excluded), with slightly thick to ca. 1.5 μm thick walls. (2) Thin-walled cystidia scattered in hymenium, colorless, subulate, sometimes containing small oil-drops, 18-25 × 2.3-3 μm, with thin walls. Basidia sometimes repetitive, narrowly clavate, 20-26 × 3.5-4 μm, 4-sterigmate. Basidiospores broadly ellipsoid or ovoid, bearing fairly distinct apiculus, with homogeneous contents, 4-5.2 × 2.7-3.5 (-3.8) μm, IKI–. CB–.

　Note： Generic placement of this species has not settled. Stalpers and Buchanan (1991) placed this species in the genus Ceraceomyces J?lich, but the lamprocystidia and the relatively thick hymenial layer are not quite representative in this genus. Judging from the characteristics, it seems to be intermediate between Ceraceomyces and Phlebia unica (Jacks. & Deard.) Ginns. (= P. cremeoalutaces (Parm.) Larsson & Hjortstam), due to the more or less horizontal subicular hyphae, distinctly thickening hymenial layer and the presence of lamprocystidia.
