Amanita virosa

 Amanita virosa, or Death Angel, is a poisonous mushroom native to Europe, where it is commonly known as Destroying Angel. It is found in mixed oak-hardwood conifer forests, other natural areas, or in the landscape, either singly or in small groups.  It is not found in North America.  Note, however, that other, equally poisonous members of the Aminata family are found in North America, such as A. bisporigera.

The cap of A. virosa is white, smooth, and the center may become a dull tan with age. The gills are white, not attached to the stalk, and close. The stalk is white, cottony to somewhat pearly, and sometimes with a bulbous base. The annulus (ring) is white, large, flaring, persistent, and is located at the top of the stalk. A white cup-like sheath (volva) is found at the base of the stalk. The spore print is white.

A. virosa is a larger species than A. bisporigera, but equally poisonous. Its identifying characteristics include its annulus and volva. When ingested, there is a lag period following initial symptoms which can lull the patient into a false sense of security, believing that the danger has passed.
