The cap is 3–10 cm in diameter, initially convex before flattening out somewhat. The margin is rolled inward, and viscid, cuticle which is often slightly spotted, smooth and with small fugacious viscid concolorous flocci. The color varies from dirty brownish or brownish-rust to ochre or grayish-bluish in the center. The margin is fibrillose (covered with roughly parallel threadlike filaments), then smooth, with a violet or reddish-violet to grayish-brown tinge, then concolourous with the center of the cap. The gills are thin and crowded closely together, broadly emarginate (notched), dark violet when young, with edges often slightly denticulate (finely toothed). The tinge and intensity of the violet coloring is similar to that of the wood blewitt (Rhodopaxillus nudus). The stem is solid, vivid violet paling to violet-purple or violet-brown, with a distinctly marginate bulb 3–4 cm wide, otherwise almost cylindrical towards the base. The cortina (a cobweb-like partial veil consisting of silky fibrils) is violet. The flesh is violet-lilac or violet, paling slightly when mature, and with a weak, unpleasant smell and mild taste. When cut or broken it turns purple, like the gills. It is an edible mushroom of medium quality.
I haven't adjusted the saturation - this is the actual color!
