Russula adusta is a species of mushroom characterized by its brown to dark brown cap, white to cream-colored gills, and white stem. In East and Central Texas, it typically fruits from spring to fall, often in association with oak and pine trees. The cap is 3-8 cm in diameter, convex to flat, and may develop cracks or wrinkles with age. The flesh is white, brittle, and has a mild to slightly bitter taste. It can be found in a variety of habitats, including woodland edges, clearings, and along trails, particularly in areas with rich soil and abundant leaf litter.
