Lepiota atrodisca is a small to medium-sized mushroom with a reddish-brown cap and white gills. It grows solitary or in small groups on the ground in wooded areas, particularly under oak and pine trees. In East and Central Texas, it typically fruits from spring to fall, with peak abundance during the summer months. The cap is 1-4 cm in diameter, initially convex then becoming flat, and is covered with fine, dark reddish-brown scales. The stem is slender, 2-6 cm long, and white with a reddish-brown base. This species is considered inedible due to its potential toxicity.
