AI-generated description

Lactarius uvidus is a species of milk cap fungus characterized by its small to medium size, grayish-brown to purplish-brown cap, and white to pale yellowish gills. In East and Central Texas, it typically fruits in the fall, often associated with oak and pine trees. The cap is 1-4 cm in diameter, convex to flat, and may develop a depressed center. The stem is slender, 1-3 cm long, and concolorous with the cap. The spore print is white, and the flesh exudes a pale yellowish to whitish milk when cut or bruised. It can be found in a variety of habitats, including woodland edges, savannas, and along roadsides, often in areas with rich soil and abundant leaf litter.
