Description:
Pileus 2.5–3.5 cm broad, at first plane, with age plano-depressed, dry, entire, becoming even; disk even, at first dark reddish brown (8E7, 8E8), then brownish red; margin inrolled (slightly when young), when young deep red-brown; surface matted tomentose, becoming subtomentose, with NH4 blue. Flesh 3–4 mm thick, yellow, staining absent; odor and flavor mild. Hymenophore lamellate, decurrent. Lamellae subdistant, 3–4.5 mm wide, not anastomosing, intervenose, when young bright yellow (2A7), with age yellow, staining blue; edges even. Stipe 2.3–5.1 cm long, 6 mm wide, equal, sinuate, dry; upper half when young fibrillose, white with a red-brown line next to the hymenophore, with age fibrillose or subfibrillose; lower half when young subfibrillose, brownish red (7C5), with age slightly roughened-fibrillose or subfibrillose, red or buff tan; fibrils on upper half when young brown or reddish (8E8); base yellow, not staining; interior solid; flesh above when young whitish yellow, with NH4 blue. Basal mycelium white. Fleeting-amyloid reaction positive. Basidiospores 9.8–11.2 µm long, 3.5–4.2 µm wide, mean Q = 2.72, subfusoid, smooth, with SEM smooth to finely rugulose, slightly amyloid, in KOH ochraceous. Basidia 24.5–32.2 µm long, 7–7.7 µm wide, clavate, hyaline, four-sterigmate. Hymenial cystidia 62.3–84 µm long, 7–11.2 µm wide, numerous on sides and edges of lamellae, thin-walled, hyaline, lanceolate, encrusting pigment present (in some). Hymenophoral trama bilateral, with age divergent; hyphae cylindrical, hyaline, amyloid. Pileipellis hyphae a trichodermium, in KOH pale yellow or hyaline, inamyloid; cylindrical, smooth, thin-walled, granular content present (some). Pileus trama hyphae hyaline, smooth, thin-walled. Stipitipellis hyphae vertically oriented, parallel, giving rise to clusters of caulocystidia, cylindrical or clavate, hyaline. Stipe trama hyphae parallel, cylindrical. Clamp connections absent.
