Lactarius torminosulus is a member of the large milk-cap genus Lactarius, in the order Russulales. A European species, it was officially described in 1996 from collections made in Norway. Fruit bodies (mushrooms) are small to medium-sized, yellowish orange in colour. Young specimens have a hairy cap margin; these hairs slough off in maturity—a field characteristic that can be used to help distinguish this species from the similar Lactarius torminosus. The fungus grows in a mycorrhizal association with dwarf birch species.
