4A1FCB5DFFEBFF8E4180FA7FFA14FECF.taxon	description	Description: — Basidiomata omphalinoid. Pileus 21 – 42 mm in diam., depressed in the center, beige-brown (2 B 3) to dark brown (5 E 8), dull when dry, darker towards the center; surface nearly glabrous, hygrophanous; margin slightly undulating, irregularly crenate to entire, radially striate, white (1 A 1) to wheat-colored (4 B 2), translucent when moist. Context thin, translucent, unchanged in color when injured. Lamellae decurrent, thin, shallow towards margin, whitecream (5 A 1) to light cream (3 A 2), with numerous lamellulae; edge entire. Stipe slender, 30 – 85 × 3 – 6 mm, central, cylindrical to flattened, equal or slightly tapering towards apex, hollow, concolorous with pileal surface, longitudinally striate; surface covered with white (1 A 1) to white-smoke (5 B 2) filamentous or patchy appendages. Basidiospores [80 / 4 / 2] 6 – 10 × 3.5 – 5.5 μm, Q = 1.20 – 2.13 (2.86), Q m = 1.67 ± 0.17, broadly ellipsoid to ovoid or pyriform, thin-walled, smooth, inamyloid, nondextrinoid, hyaline in KOH. Basidia 21 – 30 × 4 – 7 μm, narrowly clavate to subcylindrical, 4 - spored, hyaline in KOH. Hymenophoral trama regular, consisting of subcylindrical, subinflated, thin-walled, frequently branched, 2 – 17 μm wide hyphae, hyaline in KOH. Pileipellis subrepent, made up of interwoven filamentous hyphae; hyphae cylindrical to subinflated, 2 – 17 μm wide, thin-walled, yellowish to hyaline in KOH; terminal cells 32 – 45 × 2 – 4.5, thin-walled, flexuose to cylindrical or irregularly branched, occasionally with several excrescences or weakly coralloid. Stipitipellis made up of longitudinally arranged hyphae; hyphae cylindrical, parallel, frequently branched, thin-walled, nondextrinoid, 3.5 – 19 μm wide, faintly olivaceous in KOH; terminal cells flexuose to cylindrical or irregularly branched, sometimes with several excrescences. Hyphal system monomitic. Clamp connections present. Additional specimen examined: — CHINA.
