🔬 Morphology
Cap
Amethyst deceiver
The cap is small to medium: 2-7 cm across, hemispherical to convex with an inrolled edge in young mushrooms, later convex-flattened with a small bump in the center, or depressed. The color is deep amethyst purple, lilac-purple in fresh, moist mushrooms. As it dries and ages it fades to grayish-lilac, then to pale cream with a purple tinge. The surface is silky-matte, slightly damp in wet weather.
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.
Hymenophore
Amethyst deceiver
Gilled hymenophore. The gills are widely spaced, thick, attached or slightly decurrent. Their color echoes the cap — deep amethyst purple, with a whitish, floury bloom (spores). The spore print is white.
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).
Stem
Amethyst deceiver
Stem 5-10 cm tall, 0.5-1 cm thick, slender, cylindrical, often curved. The color is purple, matching the cap, lengthwise fibrous. At the base — white mycelial fuzz. No ring. The stem becomes hollow in old mushrooms.
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.
Flesh
Amethyst deceiver
Flesh thin, lilac-purple, soft. Doesn't change color when cut. No pronounced taste, faint aroma.
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.
Smell
Amethyst deceiver
Faint, pleasant mushroomy, neutral. Taste mild, with no particular notes. Not for bold-flavored dishes — nobody picks it for its aroma.
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.
