Ringed Conecap
deadlySmall brown lawn mushrooms with rusty-brown spores can contain amatoxins.
Other lawn mushrooms
cautionCollect 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.
