Description:
Hat 4-8 cm in diameter, first round-bell-shaped, then convex with a high blunt tubercle, convex prostrate, sometimes with a wide tubercle, often with an uneven surface, thick, silky fibrous, shiny, smooth, sticky in wet weather, lilac- silvery, whitish-lilac, then with an ocher, yellow-brown middle, fading to dirty whitish
Records of medium frequency, narrow, with an uneven edge, adherent with a tooth, first gray-bluish, then bluish-ocher, later brown-brown with a light edge. The cobweb cover is silver-lilac, then reddish, dense, then transparent-silky, rather low attached to the stem, clearly visible in young mushrooms.
Spore powder is rusty-brown.
Leg 6-8 (10) cm long and 1-2 cm in diameter, club-shaped, slightly mucous below the girdle, solid, then made, white-silky with a lilac, purple tint, with whitish or rusty, sometimes disappearing girdle.
The flesh is thick, soft, watery in the leg, grayish-bluish, then turning brown, with a slight unpleasant musty odor.
Spread:
The white-violet cobweb lives from the end of August to the end of September in coniferous, mixed and deciduous forests (with birch, oak), on moist soil, in small groups and singly, not often.
The similarity:
The white-purple cobweb is similar to the inedible goat’s cobweb, from which it differs in a general pale purple tone, a very slight unpleasant odor, grayish-bluish flesh, a longer stalk with a less swollen base.
Evaluation:
Cobweb white-purple – an edible mushroom of low quality (according to some estimates, conditionally edible), used fresh (boiling for about 15 minutes) in second courses, salted, pickled.
