Lactarius corrugis resembles Lactifluus volemus, which also produces latex that stains brown. By comparison, Lactarius hygrophoroides has a pinkish-orange cap. This mushroom grows under oak trees in eastern North America, and can be found between July and September. Lactarius corrugis is classified as a choice edible mushroom.
