Field Mushroom / Meadow Mushroom
Agaricus campestris
Type: gilled mushroom
Physical Characteristics
Convex to flat white cap, often with a slightly fibrous texture. Free-standing, crowded gills that turn from pink to a deep chocolate-brown as the mushroom matures. Squat white stem with a delicate, often transient ring (annulus). Dark brown spore print.
Habitat & Growing Conditions
Grows primarily in grassy areas such as lawns, pastures, and parks; often found in fairy rings. It is not associated with trees (non-mycorrhizal).
Season & Fruiting Time
Late summer to autumn, particularly after periods of heavy rainfall.
Similar Looking Species
Agaricus xanthodermus (Yellow Stainer), which stains bright yellow when bruised and smells of phenol/ink; and various white Amanita species which have white gills and a volva at the base.
Ecological Role
Saprophytic: it obtains nutrients by breaking down organic matter in the soil and grass.
Safety reminder
AI mushroom identification is a best-effort estimate and can be wrong. Never use it to decide whether a mushroom is safe to handle or eat — always confirm with a qualified mycologist before any consumption.
