Agaricus bisporus

Rare card · No. 53090

Agaricus bisporus, the cultivated mushroom, is a basidiomycete mushroom native to grasslands in Eurasia and North America. It is cultivated in more than 70 countries and is one of the most commonly and widely consumed mushrooms in the world. It has two color states while immature – white and brown – both of which have various names, with additional names for the mature state, such as chestnut, portobello, portabellini, button, cremini, and champignon de Paris (see Names below). Some poisonous lookalikes in the wild, such as Entoloma sinuatum, may appear similar. Amanita phalloides, or death cap, which is extremely toxic, has also been mistaken for A. bisporus. Often grows in rich soil and compost.
