- Description
-
The large size, powdery cap and enlarged base of the stalk, as well as the strong chlorine or rotting meat odor, make this easily recognized. There are other species of Amanita that have a chlorine odor but have more persistent scales and an annulus (ring) on the stalk. All such Amanitas should be avoided.
The cap is very large, up to 10 inches in diameter, whitish, covered with dense, soft, powdery scales which may wash off easily in rain. The Gills are close, whitish, with cottony edges. The stalk is greatly enlarged below, often with the lower 1/3 buried in soil, and whitish. The Annulus (ring) is fragile, whitish, and often left on edge of caps with no tissue in the stalk. The Spore print is white; strong chlorine odor, especially when broken open or enclosed in a container for some time.
Typically found growing singly in forested or natural areas or in the landscape. It is usually under oak or pine trees, and less often under pine.
