Hymenial surface yellowish gray, no color changes in KOH, smooth, sometimes cracked; margin thinning, concolorous, pruinose. Hyphal system monomitic; hyphae sim-ple-septate. Subiculum composed of a thin basal layer, usually indistinct; hyphae colorless, horizontal, 2-4 μm diam., thin- or slightly thick-walled. Crystal masses scattered in subicu-lum. Hymenium thickening, with fairly dense texture; hyphae colorless, 2-3 μm diam., thin-walled. Cystidia lacking. Cystidioles numerous, colorless, capitate, subcapitate or clavate, 7-20 × 2.5-3.5 μm. Basidia clavate, 14-20 × 3.5-4 μm, 4-sterigmate. Basidiospores broadly ellipsoid, smooth, thin-walled, 3-3.8 × 2-2.8 μm, IKI-, CB-.

　Note： This species is similar to Phanerochaete parvispora Sheng H. Wu & Losi in basidiospore sizes. The type specimen of P. parvispora has a whitish hymenial surface (Wu & Losi, 1995), whereas that of P. flavidogrisea is yellowish gray. Moreover, capitate cys-tidioles of P. flavidogrisea are lacking in P. parvispora.
