 Description： |
Basidiocarp effuse, adnate, ceraceous in old parts, 150-300 μm thick in section. Hymenial surface Mummy Brown, slightly darkened in KOH, smooth, cracked when old and exposing white filamentose subiculum; margin paler or white, filamentose or rarely byssoid. Hyphal system dimitic with quasi-binding hyphae; most hyphae simple-septate, a few septa in subi-culum with double clamp connections. Subiculum uniform, with ± dense texture; generative hyphae ± horizontal, somewhat vertical near subhymenium, colorless, distinct, rather straight, 3.5-7 μm diam., with 0.5-0.9 μm thick walls, usually encrusted with scattered to crowded crystals, which gradually dissolve in KOH, anastomoses occasional; quasi-binding hyphae commonly occurring in subiculum, colorless, richly ramified, 0.8-2 μm diam., thin-walled. Hymenial layer with compact texture, thickening; hyphae colorless, aggluti-nated, narrower than those of subiculum, thin-walled; orange-yellow resinous material abundant in subhymenium, dissolving in KOH. Cystidia numerous, projecting for approximately half their lengths, cylindrical, with acute apices, 23-40 × 3.3-4.3 μm, thin- or slightly thick-walled. Basidia narrowly clavate, 23-33 × 5-6 μm, 4-sterigmate. Basidiospores ellipsoid or narrowly ellipsoid, adaxially flattened or slightly concave, with a minute apiculus, smooth, thin-walled, usually with yellowish oil-drops, (5-) 5.3-6.3 (-6.7) × 2.4-3 μm, IKI-, CB-. |
