The most common in the Amanita species found in the midwest and eastern North America. They typically appear in early to mid-summer in forests or natural areas or landscapes. They are found singly or scattered, usually under hardwood trees, especially oaks, occasionally under pines. The roots of the mushroom (fungal species) become one with the roots of adjoining host plants. This is referred to as an ectomycorrhizal relationship.
This species is suspected to be toxic and is related to other known toxic species of Amanita and should be avoided. The cap is orange to yellow-orange, sticky, with yellow warts, up to 4 inches in diameter. The gills are crowded, white, and free from the stalk. The stalk is a pale yellow to white, with an enlarged, oval base, and powdery appearance. The annulus is white, persistent, and located near the top of the stalk. The volva is yellow, fragile, and often left in the soil when picked. The spore print is white.
The most distinguishing feature of this mushroom is found at the base of the stem. The universal veil becomes fragmented, leaving behind yellow remnants.
