Agaricus campestris

Field mushroom

The field mushroom of pastures and lawns, appearing after rain from late summer. It is a soil saprotroph that thrived on manured horse pasture and is becoming scarcer as horses leave grassland. It is not commercially grown because it matures fast and keeps poorly, but it can be tried like its relative the button mushroom.
