 Description: Basidiocarp usually effuse-reflexed to slightly pileate, rarely resupinate, usually fairly tough, separable, 200-600 μm thick in section, membranaceous. Hymenial surface pale gray, grayish yellow or ochraceous, usually brownish lining growth margins, zonate, smooth, usually velutinous due to the emergent cystidia. Abhymenial surface filamentose. Hyphal system dimitic; generative hyphae nodose-septate. Subiculum with dense texture close to the substratum, looser near subhymenium. Skeletal hyphae generally dominant in subiculum,  horizontal, yellowish or slightly brownish-tinted, 3-6 μm diam., thick-walled. Generative hyphae  horizontal, colorless, dominant and forming a basal layer next to the substratum, fairly sparse elsewhere, 2.5-4 μm diam., thin-walled. Subhymenium slightly thickening, with dense texture; generative hyphae mainly vertical. Skeletocystidia numerous and distinct, of subiculum origin, emergent or immersed, subulate, yellow or brownish tinted, heavily encrusted for apical parts, 20-35 μm diam. (encrustation included), up to ca. 200 μm long, 2-8 μm thick-walled. Basidia generally clavate, slightly flexuous, with stalked bases, 65-75 × 8-10.5 μm, 4-sterigmate. Basidiospores ellipsoid, adaxially slightly concave, usually with a big oil-drop, 9.5-13.5 × 4.5-6 μm, thin-walled, IKI–, CB–.

 Note: Microscopic features of Lopharia cineracens and L. mirabilis (Berk. & Br.) Pat. are inseparable. Hymenial surface of L. cinerascens is smooth, while is tuberculate-odontioid to irpicoid in that of L. mirabilis. Lopharia cineracens is very frequently encountered from low altitude Taiwan, grows on branches of various deciduous trees and causes a white rot.
