Russula ballouii is a species of mushroom characterized by its reddish-brown to brown cap, white gills, and white stem. In East and Central Texas, it typically fruits from June to October, often in association with oak trees, particularly Quercus stellata and Quercus buckleyi. The cap ranges from 3-8 cm in diameter, and the stem is 3-6 cm tall and 1-2 cm thick. Spore prints are white, and microscopic examination reveals elliptical spores with warts and reticulations. This species is considered edible, but caution is advised due to potential confusion with other Russula species.
