Description : The cap of the mushroom is 5–25 cm (2–8 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 close, adnate to decurrent, white to cream colored.
The stem 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 has a foul-smelling odour, which has been described as slightly farinaceous to rancid.
Biology: Often gregarious. It appears from late Summer to late Autumn.
Habitat: forests of deciduous or conifers trees.
Distribution: Europe, North America.
Caution: Considered edible by some mycologists, it must be treated with caution.
It must be boiled before preparation since it can be a source of nausea.
The main danger lies on the confusion with Entoloma livida, a poisonous mushroom. This late species is quite similar, but the gills are yellowish to pinkish.
