Common Cultivated Mushroom

The mushrooms we buy in the grocery store Agaricus bisporus belong to a family Agaricaceae that has both edible and poisonous species. Cultivated mushrooms are grown in dark cellars on soil that contains plenty of rotting organic matter. Under the cap of each mushroom you can see a little collar on the stalk which is the remains of the membrane that covers the gills of the young fruiting body. [CH] {FW}
