　Description： Basidiocarp effuse, ±adnate, subceraceous, 120-300 µm thick in section. Hymenial surface Ivory Yellow in young parts. Pale Olive-Buff when old, slightly greenish yellow in KOH, smooth or slightly tuberculate, rarely cracked; margin paler or white, thinning, pruinose or arachnoid. Hyphal system monomitic; hyphae simple-septate. Subiculum fairly uniform, composed of medullary layer, with compact texture near subhymenium, with rather loose texture elsewhere; hyphae ± horizontal, somewhat vertical near subhymenium, yellowish or colorless, rather distinct, straight, somewhat tortuous near subhymenium, 3.5-6 µm diam., with 0.4-0.7 µm thick walls, not encrusted, anastomoses occasional. Hymenial layer with compact texture, somewhat thickening; hyphae vertical, colorless, ±agglutinated, slightly narrower than those of subiculum, thin-walled. Cystidia numerous, projecting for approxi-mately half their lengths, colorless, subulate, or cylindrical with acute or obtuse apices, pro-jecting parts encrusted with thin layer of crystals, which gradually dissolve in KOH, 35-80 × 5-9 µm (encrustation excluded), with 0.3-2 µm thick walls. Basidia subclavate, usually guttulate, 24-33 × 5.5-7 µm, 4-sterigmate. Basidiospores broadly ellipsoid or subglobose, smooth, thin-walled, usually with one or two prominent yellowish oil-drops, (4.8-) 5-5.8 (-6.2) × 3.3-4.3 µm, IKI-, CB-.

　Note： No known species appears to be very similar to this new taxon. It differs from Phanerochaete velutina (DC.: Fr.) P. Karst. in having narrower subicular hyphae, smaller cystidia and differently shaped basidiospores.
