Description:Basidiomata small to medium-sized. Pileus 2.5–6 cm diam., convex to applanate, usually slightly depressed in the centre, smooth, dry but subviscid when wet, light yellow to vivid yellow (3A5–8) or to deep yellow (4A5–8), or light orange to dark orange (5A5–8), becoming paler when dry; margin even, straight or upturned and occasionally split when mature. Lamellae up to 7 mm wide, adnate to sinuate or decurrent, distant, 17–22 lamellae per pileus, with 1–3 lamellulae between two complete lamellae, usually furcate, often interveined or anastomosing at lamella base, thick, concolorous with the pileus; lamellar base and lamellulae irregular and occasionally the whole hymenophore irregular; lamellar edge even and concolorous. Context concolorous with lamellae and pileus, unchanged when cut. Stipe 4–6.5 × 0.6–1.2 cm, central or occasionally eccentric, subcylindrical, moderately to densely covered with white tiny adpressed bres. Odour indistinct.
Basidiospores 8–10(–10.5) × (4.5–)5–7(–7.5) μm, Q = (1.3–)1.5–1.8, Qm = 1.6– 1.7, ellipsoid to ellipsoid-oblong, ovoid, not constricted, thin-walled, hyaline, smooth.
Basidia 41–80 × 4–10 μm, strongly elongated, narrow clavate, 4-spored, thin-walled; sterigmata up to 10 μm long; ratio of basidia to basidiospore length over 5 and up to 8. Hymenophoral trama subregular, yellow, made up of thin-walled hyphae 3–15 μm wide and usually less than 100 μm long and some conducting elements. Pileipellis a cutis, made up of repent hyphae 3–9 μm wide with the terminal elements 30–80 μm long. Stipitipellis a cutis, with thin-walled hyphae (5–7 μm wide). Clamp-connections present in all tissues.
