Description
This conical agaric is medium-sized, greyish brownish and later blackening; it grows generally in tufts, in fields, gardens and waste ground, near broad-leaf tree stumps or buried wood. It sometimes pushes up through tarmac paths and less frequently near the bases of living trees.

Cap egg-shaped, expanding to become slightly umbonate with age. The colour is gray to gray-brown. Flesh is white, hollow and medium in young specimens but soon discolors and deliqueces slowly from the margin. Gills free, extremely crowded and edged with white. Spores are black. Stem is white and smooth with fine, reddish brown fibrils at base.

Similar species Coprinus insignis has warty spores. Coprinus micaeus is smaller and more fragile. It granulates when young.
