| Description： |
Basidiocarp resupinate, effuse, adnate, membranaceous, 70-200 μm thick in section. Hymenial surface pale yellow to light yellow, smooth or slightly tuberculate, extensively cracked; margin thinning, paler, arachnoid-pruinose. Hyphal system monomitic; hyphae nodose-septate. Subiculum bi-layered, composed of basal layer and medullary layer. Basal layer with compact texture, up to ca. 20 μm thick, sometimes indistinct; hyphae colorless, ±glued together, 2-3 μm diam., thin-walled. Medullary layer with fairly loose texture; hyphae colorless, variously oriented, 2-3 μm diam., thin-walled. Hymenium thickening, not clearly differentiated from medullary layer, with dense texture; hyphae ± vertical, much branched, colorless, slightly narrower than those of subiculum, thin-walled. Gloeocystidia numerous, mostly immersed, cylindrical, sometimes slightly flexuous, colorless or subcolorless, 40-90 × 8-15 μm, walls up to ca. 1.2 μm thick, SA+. Basidia narrowly clavate, 20-30 × 4-5 μm, 4-sterigmate. Basidiospores ellipsoid or broadly ellipsoid, verrucose (smooth in KOH), thin-walled, (4-) 4.3-5 (-5.2) × 2.8-3.2 μm, IKI bluish black, CB–. |
