Description
The cap is up to 8 cm (3.1 in) in diameter, convex in shape, sometimes with an umbo, and whitish in color. After being scratched or bruised, the cap turns yellow. The stipe is 8–12 cm (3.1–4.7 in) long by 1–3 cm (0.39–1.18 in) thick and bulbous. A large, white annular ring is present on the stipe. The gill attachment is free, and the color is initially grayish but turns brownish after the spores are developed. Specimens smell slightly of anise. The spore print is brown to purple-brown. Spores are elliptical in shape, and are 6–8 by 4–5 µm. The surface of the cap will stain yellow if a drop of dilute potassium hydroxide is applied.
