Agaricus campestris
The field mushroom, also called meadow mushroom, grows in meadows, pasture and open lawns, often after mild damp weather. In Switzerland it can appear from late spring into autumn. A white mushroom in grass is never automatically Agaricus campestris.
Meadows, pastures, lawns and other open grassland on active, uncontaminated soil.
Spring into autumn, often after mild and damp periods.
Identification and lookalikes
Yellow stainer, other white Agaricus species and dangerous young white Amanita species can look similar. Smell, staining, gill colour, ring, stem and complete base all matter. Pink gills alone are insufficient.
The map helps you search. Never identify.
Cepello does not identify mushrooms and never confirms that a specimen is edible. Have your entire collection checked by an official inspection service.

Frequently asked questions
Why is it called a field mushroom?
It typically fruits in open grassland and pasture rather than woodland.
Do pink gills confirm a field mushroom?
No. Gill colour changes as specimens mature and cannot establish the species by itself.
