 Description： |
Basidiocarp resupinate, effuse, adnate, ceraceous or subceraceous, 100-600 μm thick in section, sometimes composed of two growth layers (new hymenial layer directly arising from old hymenial layer). Hymenial surface light orange, smooth or slightly tuberculate, cracked extensively; margin rather determinate, concolorous. Hyphal system monomitic; hyphae nodose-septate. Subiculum fairly uniform, thin, composed of basal layer with compact texture; hyphae mainly horizontal, colorless, glued together and usually indistinct, 2-4 μm diam., thin- or slightly thick-walled. Hymeniumdistinctly thickening, not clearly differentiated from subiculum, with compact texture; hyphae colorless, vertical, glued together and indistinct. Crystal masses usually crowded or scattered in subiculum and Hymenial layer. Gloeocystidia numerous, mostly immersed, cylindrical or tubular, somewhat wider basally, slightly flexuous, orange-yellow or subcolorless, 5-10 μm diam., up to ca. 100 μm long, SA+. Basidia clavate, 17-27 × 5-6 μm, 4-sterigmate. Basidiospores ellipsoid or broadly ellipsoid, adaxially flattened or slightly concave, with a distinct apiculus, verrucose-aculeate (smooth in KOH), thin-walled, (5.2-) 5.8-6.5 (-6.8) × 3.3-4 μm, IKI bluish black, CB–. |
