How to recognise it
Look for a hygrophanous cap that changes color as it dries, mottled dark brown gills, and a dark brown (not jet black) spore print.

Panaeolus cinctulus (which has a jet black spore print) and various species of Conocybe (which usually have orange-brown spore prints).
Ecological role
Saprophytic, breaking down organic matter in soil and grass thatch.
Notes
It is one of the most common mushrooms found in suburban lawns. It is of interest to mycologists due to its extremely wide global distribution and ability to thrive in man-made environments like golf courses and parks.
