Choose the hemisphere you want to study. Country detection is approximate and some countries span the equator.

Lookalikes to rule out

Fool's funnel has crowded, decurrent gills and a frosty white cap.

Small brown lawn mushrooms with rusty-brown spores can contain amatoxins.

Other lawn mushrooms

caution

Collect only where every specimen has been checked; lawns host many small species.

Identification

Caps are tan to buff with a broad central bump, drying paler. The gills are well spaced and barely attached to the stem. The thin stem is tough: twist it and it bends rather than snaps. They grow in rings or arcs, often at the edge of a band of darker grass.

Uses and ecology

Fairy ring mushrooms dry on the lawn and revive after rain, which makes them easy to dry for cooking. Only the caps are used. Avoid lawns treated with chemicals.

Memorable fact

Rings expand outward each year, and some in old pastures are estimated to be centuries old.
