Description: | Basidiocarp resupinate, effuse, adnate, membranaceous, 100-200 μm thick in section. Hymenial surface pale orange to orange white, smooth, not cracked; margin thinning or rather determinate, concolorous, arachnoid. Hyphal system dimitic; generative hyphae simple-septate. Subiculum fairly uniform, composed of medullary layer with fairly loose texture; generative hyphae ± horizontal near substratum, variously oriented elsewhere, colorless, moderately ramified and loosely interwoven, 2-4 μm diam., thin- or slightly thick-walled; binding hyphae sparsely distributed, more abundant near substratum, brownish, with ca. 0.5 μm thick walls, sometimes almost solid. Hymenial layer differentiated from subiculum, thickening, with compact texture; hyphae mainly vertical. Gloeocystidia numerous, mostly arising from subiculum, colorless or slightly yellow, tubular and moniliform, up to ca. 120 μm long, 4-8 μm diam., thin- or slightly thick-walled, slightly SA+. Basidia utriform, usually with a stalked base, 20-35 × 5-6 μm, 4-sterigmate. Basidiospores ellipsoid or broadly ellipsoid, smooth, thin-walled, bearing a distinct apiculus, with homogeneous contents, 5-6.5 × 3.3-4 μm, IKI slightly bluish black, CB–. | |||

Note: | In G. graminicola, the single to multiple clamped hyphae of FB-mycelia are mostly dikaryotic and rarely with 3 nuclei, resembling the holocoenocytic nuclear behavior but with lesser number of nuclei. | |||
