an order of fungi of the class Basidiomycetes with fleshy annual fruiting bodies, each consisting of a cap and a stalk. The hymenophore, which is lamellar or, more rarely, tubular, can easily be separated from the cap tissue. Around 3,000 species of Agaricales are known. They include the widely known forest mushrooms, the vital activities of which are closely dependent upon the roots of trees—the boletus, such as the edible boletus, the rough-stemmed boletus, the red boletus, the butter mushroom, the mossiness mushroom, and others and the gill fungi, such as the russula, the wooly milk-cap, the saffron milk cap, and others. There are also the mushrooms that grow in fields, meadows, gardens, weedy areas, and heavily manured areas, such as the common mushroom and the shaggy mane. All of these mushrooms are edible. One of them, Agaricus bisporus, is widely cultivated in more than 20 nations.
Agaricales also includes the most dangerous poisonous mushrooms, such as the death cap, the fly agaric (red cap, panther cap, and colymbiformes), and Amanita mappa.
