🔬 Morphology

Cap

Sordid blewit

Cap 4-8 cm across; convex with an inrolled margin when young, later flattening out with a thin, wavy margin. Color lilac-grayish, violet-gray, with a distinct violet tint when young, fading with age to a dingy grayish lilac or cream with a trace of violet. The surface is silky-matte and smooth, slightly sticky in wet weather.

Violet webcap

Cap 5-15 cm across, hemispherical with an inrolled margin in young mushrooms, later becoming convex-flat with a low umbo. Color deep violet, inky purple, almost black in the center. Surface velvety-scaly, with fine violet-inky scales — a hallmark of the species. In damp weather it looks matte and velvety.

Hymenophore

Sordid blewit

Gills. The gills are crowded, thin, notched where they meet the stem, and break off easily. Color lilac-violet in young mushrooms, lilac-cream with age. The spore print is pale pinkish-cream (typical of the genus Lepista).

Violet webcap

Gills — attached to the stem, moderately spaced, deep violet, darkening with age to purple-black, then to rusty brown as the spore powder ripens. Spore print rusty brown. In young mushrooms the gills are covered by a cobweb-like partial veil (cortina) with a purple tint.

Stem

Sordid blewit

Stem 3-6 cm tall, 0.5-1.2 cm thick, cylindrical, slightly thickened toward the base. Color violet-lilac, matching the cap, lengthwise fibrous, with whitish mycelial fuzz near the base. No ring. The stem flesh is firm.

Violet webcap

Stem 8-12 cm tall, 1.5-2.5 cm thick, cylindrical, thick and fleshy, with a bulbous swelling at the base. Color deep violet, matching the cap, paler toward the base. The surface has fine violet fibers. Remnants of the cobwebby cortina on the stem — purple in young mushrooms, covered in rusty-brown spores in old ones.

Flesh

Sordid blewit

Flesh of medium thickness, lilac-white, soft, firm in young mushrooms. It doesn't change color when cut. It has a pleasant fruity, perfumed aroma.

Violet webcap

Flesh firm, violet in young mushrooms, turning gray-violet to brownish with age. When cut, it does not change color. Smell faint, mushroomy; in some populations with a hint of cedar.

Smell

Sordid blewit

Pleasantly fruity and perfumed, with a note of ripe fruit — typical of the genus Lepista. One of the most distinctive aromas among the lilac-violet mushrooms. The taste is mild; after boiling, pleasantly mushroomy.

Violet webcap

Faint, pleasant and mushroomy, with a subtle resinous or cedar note in some populations.
