The stipe is thick, cylindrical, powdery, has a fragile, cottony ring, and a large, white to ochraceous-cream volva at the base.

It is separated by the deep ochraceous to russet-orange colour of its volva, the persistent pendulous ring on the stipe, and the smooth cap margin, without vellar remains.

Amanita ovoidea is a symbiotic fungus, forming mycorrhizal associations with pine trees, as well as evergreen and deciduous oaks.

[5] In southern France, some people were inflicted with acute kidney injury because they accidentally consumed A. proxima, mistaking it for A. ovoidea.

[12][13] A 2008 study on the minerals in fungi from northwest Turkey, including this species, concluded that A. ovoidea was safe to eat and could fulfill nutritional needs.
