Description
The cap is vivid yellow, conical to broadly convex cap and up to 15 mm (0.6 in) in diameter. When young the cap tends to be conical or bell-shaped becoming plane or flat at maturity. The margin is striated. The surface is moist, galabrous, and somewhat hygrophanous. The flesh is thin, pallid, and yellowish. Odor and taste are not distinctive. The gills have an adnate attachment and are a pale yellowish color. They are subdistantly spaced. The sturdy stem is 10 to 20 mm (0.4 to 0.8 in) long by 1 to 1.5 mm (0.04 to 0.06 in) thick. The stipe is central, equal (i.e., roughly equal in thickness at the top and bottom), and dark orange to yellowish.[citation needed]
Microscopic characteristics
The spores are 7–9 x 4–5 µm, smooth, and elliptical, and weakly amyloid to inamyloid. Pleurocystidia and cheilocystidia are present.[citation needed]
