Lactarius gerardii is a medium to large-sized mushroom with a grayish-brown to tan cap, often with a depressed center, and white to pale yellow gills. The stem is typically stout and similar in color to the cap. It has a mild to slightly sweet odor and taste. In East and Central Texas, Lactarius gerardii can be found growing on the ground in association with oak and pine trees, particularly in sandy or clay soils. Fruitings often occur from summer to fall, with peak activity during late August and September. The species is considered common in the region, particularly in areas with rich soil and abundant tree cover.
