Agaricus campestris
EDIBLE* Season // Jul-Nov Family // Unknown

Description

The Meadow Mushroom is the classic wild ancestor of the cultivated button mushroom. Cap 5-12 cm across, initially rounded becoming broadly convex to flat. The cap is white to cream, smooth or with fine flat scales, often developing pinkish-brown tones with age. The gills are free, initially bright pink becoming dark chocolate brown (diagnostic - pink gills distinguish from white Amanitas). The stem is 3-8 cm tall, white, smooth, with a thin fragile ring that often disappears. The flesh is white, sometimes slightly pinkish, with a mild pleasant mushroomy odor.
