 Description： |
Basidiocarp resupinate, effuse, adnate, subceraceous or ceraceous, thin to rather thick due to several growth layers (perennial). Hymenial surface smooth, light yellow when young, brown when old, extensively and deeply cracked when old; margin rather determinate, concolorous. Hyphal system monomitic; hyphae simple-septate, cyanophilous and dextrinoid. Subiculum of a thin basal layer or indistinct; hyphae colorless or subcolorless, 2-4 μm diam., thin- or slightly thick-walled. Hymeniumdistinctly thickening, due to numerous hymenial layers, with very compact texture; hyphae vertical, yellowish brown, 2-3.5 μm diam., with thickened walls. Gloeocystidia numerous, cylindrical or tubular, slightly flexuous, with yellow contents, sometimes difficult to find from old parts, 20-60 × 5-8 μm, thin- or slightly thick-walled, SA+. Basidia subclavate, 20-30 × 4-5 μm, with thickened walls toward the basal parts probably because of internal repetition, 4-sterigmate. Basidiospores ellipsoid, smooth, thin-walled, 4.2-5.5 × 2.8-3.3 μm, IKI bluish black, CB–. |
