　Description： Basidiocarp effuse, separable, farinaceous, 20-50 μm thick in section (aculei excluded). Hymenial surface whitish, odontioid or grandinioid, not cracked; margin concolorous, thin-ning, pruinose. Aculei usually separate, ca. 10 per mm, conical, apically fimbriate owing to projecting tramal hyphae, 40-80 × 35-50 μm. Hyphal system monomitic; hyphae simple-septate. Subiculum uniform, composed of medullary layer, with rather dense texture; hyphae rather horizontal near substratum, ± vertical near subhymenium, colorless, distinct or not, rather short-celled, 1.5-3 μm diam., thin-walled. Hymenial layer with compact texture. Terminal hyphase of the trama subulate, projecting, laterally with short projections, apically covered with excreted material. Cystidia of two kinds: (1) Halocystidia numerous, capitate, 4.5-8 diam.; outer globules 8-18 μm diam., guttulate, with CB+ and slightly thick walls. (2) Astrocystidia numerous, subulate, thin-walled, apically encrusted by stellate masses of crystals. Basidia clavate, 12-20 × 4.2-5.2 μm, 4-sterigmate. Basidiospores ellip-soid, adaxially flattened, smooth, thin-walled, with prominent apiculus, (5.5-) 6-7.2 (-7.5) × 3.2-4 μm, IKI-, CB-.

　Note： Corticium granulare has earlier been considered a later synonym of Resinicium bicolor (Liberta 1969). However, it differs from the latter in having simple-septate hyphae; moreover, the terminal hyphae of the aculei are usually covered with excreted material at their apices and sometimes exhibit irregular projections on their sides. Both the type speci-men and the Taiwanese specimen grew on Poaceae.
