How to tell Wood blewit from Lilac bonnet

Cap 2-6 cm across, bell-shaped when young, later opening to convex with a low bump. Color pink, lilac, violet-purple, less often pale pink or grayish lilac, with radial grooves from the margin to the center. Surface smooth, shiny in wet weather.

Cap 5-15 cm across, when young convex with an inrolled margin, becoming with age flat and spreading. The cap skin is smooth, slightly slimy in wet weather, dry and matte in dry weather. Color vivid violet or lilac-violet when young, less often with a pink tint; with age it fades to brownish-violet, then to brownish-cream with violet traces at the margin. The margin is even, inrolled when young.

Gilled hymenophore; gills broad, distant, whitish to pale pink or lilac. Attachment notched. Spore print white.

Gilled hymenophore — the gills are adnate or slightly decurrent, very crowded, thin. Color distinctly violet-lilac when young, brownish-violet to brownish-cream with age, with a greenish-pink tint when mature. Spore print pale pink to creamy pink — characteristic of the genus Lepista.

Stem 4-8 cm tall, 0.3-0.8 cm thick, cylindrical, fragile. Color pinkish lilac, matching the cap, paler lower down. Surface smooth, with fine lengthwise fibers.

Stem 5-10 cm tall, 1.5-3 cm thick, firm, fleshy, cylindrical, thickening toward the base. Color violet to lilac-violet, often paler lower down, with whitish mycelium at the base. The surface is smooth with fine lengthwise fibers. No ring.

Flesh thin, pink to whitish, watery. Does not change color when cut. Smell a characteristic radish smell: the key diagnostic feature of the species.

Flesh firm; thin in the cap, thick in the stem, violet-whitish to pale lilac. Doesn't change color when cut or slowly fades to grayish-violet. Smell pleasant, sweetish and perfumed, reminiscent of lilac or violet, with a hint of anise, taste sweet at first, then mildly mushroomy.

A distinct radish smell, like raw radish or horseradish. It comes out when you crush the flesh. This is the most reliable feature of the species.

A distinct, pleasant, sweetish-perfumed smell — reminiscent of lilac, violet or a touch of anise. A helpful clue, but not a decisive one: the violet webcap smells faintly of cedar, and some lilac webcaps (Cortinarius camphoratus, C. traganus) smell strong and unpleasant. So check the smell together with the spore print colour.
