Cloudy Clitocybe

The cap of the mushroom is 5–25 centimetres (2–10 in) in diameter, convex with an incurved margin, becoming plane to depressed in shape. Cap colours are generally greyish to light brownish-grey, and often covered in a whitish bloom when young. The surface of the cap is usually dry to moist, and radially fibrillose. The gills are pale, adnate to short-decurrent, close and usually forked. The stem measures 5–10 cm (2–3+7⁄8 in) long and 2–4 cm wide; it is stout, swollen towards the base, becomes hollow with age, and is easily broken. It is usually somewhat lighter than the cap. The flesh is white, and very thick. It usually has a foul-smelling odour, which has been described as slightly farinaceous to spicy, or rancid. The spores are yellow and elliptical. The spore print is light yellowish.

Similar species. The species can resemble C. robusta which has a more solid white cap, C. irina which has a pinkish spore print, Ampulloclitocybe clavipes, and Harmajaea harperi. It may also be confused with the poisonous Entoloma sinuatum both in Europe or North America, though this species has pink sinuate gills. It also resembles Leucopaxillus albissimus and Tricholoma saponaceum. Leucopaxillus giganteus is also similar in stature, but is whiter. Infundibulicybe geotropa has a pale brown cap.

This species is host to the parasitic gilled mushroom Volvariella surrecta, which is found on older specimens.

The species is edible but even a small portion can cause gastrointestinal disturbances for some people.
