Russula pectinatoides is a small to medium-sized mushroom with a cap that ranges from 2-6 cm in diameter, typically yellow to orange-yellow in color, and often with a depressed center. The gills are crowded, fragile, and white to cream-colored. The stem is slender, white, and 2-5 cm long. In East and Central Texas, Russula pectinatoides is commonly found growing on the ground in deciduous and mixed forests, particularly under oak, pine, and hickory trees, from summer to early fall. It tends to thrive in moist, shaded areas with rich soil.
