Wood blewit or Goatcheese webcap

The cap is 4-9 cm across, hemispherical to conical-convex in young mushrooms, becoming convex-flat with a noticeable low umbo over time. The color is grayish-lilac, lilac-brown, with a violet tint when young, fading to grayish-ochre with age. The surface is smooth, slightly slimy in wet weather. The cap margin is thin, with fine radial fibers.

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.

The hymenophore is gilled — the gills are attached to the stem and moderately crowded. In young mushrooms they are lilac, mauve-gray, later turning rusty brown as the spores ripen. The spore print is rusty brown — a diagnostic feature of the genus Cortinarius. In young mushrooms the gills are covered by a cobwebby partial veil (the cortina) — a characteristic feature of the genus.

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.

The stem is 5-10 cm tall, 1-2 cm thick, cylindrical, with a bulbous swelling at the base. The color is lilac to violet in the upper part, paler to whitish lower down. The surface has fine lilac fibers. On the stem, remnants of the cobwebby cortina — noticeable in young mushrooms, disappearing in older ones and leaving a thin band of rusty-brown spores on the stem.

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.

The flesh is firm, white to pale lilac. When cut it does not change color. The smell is strong and sickly, camphor-like, with a note of raw potato or rancid cheese — its most characteristic diagnostic feature. The taste is mild, but given the smell it's not worth trying.

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.

Strong sickly camphor-and-potato smell, with a note of rancid cheese or a damp cellar. You can catch it from a distance. It opens up when you rub the flesh. This is the most reliable diagnostic feature of the species — few other webcaps have such a pungent smell.

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.
