　Description： Basidiocarp resupinate, effuse, adnate, subceraceous or ceraceous, 50-500 μm thick in section. Hymenial surface greyish orange to light orange, smooth or slightly tuberculate, cracked when old; margin concolorous, thinning or rather determinate. Hyphal system monomitic; hyphae nodose-septate. Subiculum fairly uniform, composed of basal layer, thin, sometimes indistinct, with compact texture; hyphae colorless, mainly horizontal, usually glued together, 2-4 μm diam., thin- or slightly thick-walled. Hymeniumdistinctly thickening, differentiated from subiculum, with dense texture; hyphae colorless, mainly vertical, 2-3 μm diam., thin-walled. Gloeocystidia numerous, mostly immersed, tubular or cylindrical, slightly flexuous, usually gradually narrowing toward apices, with orange-yellow oily contents, 5-10 μm diam., up to ca. 150 μm long, basally thick-walled and apically thin-walled in long cystidia, the walls close to bases up to ca. 2 μm thick, SA+. Basidia clavate, 25-35 × 6-7 μm, 4-sterigmate. Basidiospores ellipsoid, verrucose (smooth in KOH), thin-walled, (6.5-) 7-8 (-8.2) × 3.5-4 μm, IKI bluish black, CB–.

　Note： This species is close to Gloeocystidiellum compactum. Basidiospores are longer than those of G. compactum. These two species are incompatible (Lin 625 × Wu 880615-21, Lin 625 × Wu 890714-20).
