Black mushroom (lat.Lactarius necator) is a mushroom of the genus Millechnik (lat.Lactarius) of the russula family (lat.Russulaceae).
Description Hat ∅ 7–20 cm, flat, depressed in the center, sometimes wide-funnel-shaped, with a felt edge rolled inward. The skin is slimy or sticky in wet weather, with or without faintly visible concentric zones, dark olive color. The pulp is dense, brittle, white, becoming gray on the cut. Milky juice is abundant, white, with a very pungent taste. Leg 3-8 cm in height, ∅ 1.5-3 cm, narrowed downward, smooth, slimy, of the same color with a cap, sometimes lighter at the top, at first solid, then hollow, sometimes with depressions on the surface. Plates descending along the pedicle, forked-branched, frequent and thin. Pale creamy spore powder.
Variability The color of the cap of the black milk mushroom can vary from dark olive to yellowish-brown to dark brown. The center of the cap may be darker than the edges.
Ecology and distribution The black lump forms mycorrhiza with birch. It grows in mixed forests, birch forests, usually in large groups in moss, on litter, in grass, in bright places and along forest roads. Season from mid-July to mid-October (massively from mid-August to late September).
Nutritional qualities Conditionally edible mushroom, used, as a rule, salted or fresh in main courses. When salted, it acquires a purple-burgundy color. Before cooking, it requires a long processing to remove bitterness (boiling or soaking).
