Description

 A. virosa is a larger species than A. bisporigera (Death Angel) but both are deadly poisonous.  It is one of the most poisonous mushrooms. Its identifying characteristics include its annulus and volva (see photos). The lag period following initial symptoms is especially dangerous as the patient is lulled into a false sense of security.

The cap is white, smooth, and center may become a dull tannish white 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, cup-like sheath (volva) at the base of the stalk, and white. The spore print is white.

Found in: Forests or other natural areas, landscape, either singly or in small groups in mixed oak-hardwood conifer forests.
