Lactarius torminosus.
Lactarius torminosus, the woolly milkcap, is a large agaric fungus. First described scientifically by Jacob Christian Schäffer in 1774, it is a common species, found in North Africa, northern Asia, Europe, and North America. It grows on the roots of various trees, most commonly birch in mixed forests. The cap of the L. torminosus mushroom, up to 10 cm (3.9 in) wide, is convex with a central depression. A blend of pink and ochre hues, the cap sometimes has concentric zones of alternating lighter and darker shades. On the underside are narrow flesh-colored gills, crowded closely together. The cylindrical stem is a pale flesh color with a delicately downy surface, up to 8 cm (3.1 in) long and 0.6–2 cm (0.2–0.8 in) thick. When cut or injured, the mushroom oozes a bitter white latex. The species is highly irritating to the digestive system when eaten raw, but is valued for its peppery flavor in Russia and Finland after being cooked to destroy its toxins.
