Amanita vernicoccora was long lumped together with the fall coccoli, Amanita calyptroderma, but is now recognized as a distinct species. It can be recognized by its yellow to pale yellow short-striate cap that is partially covered by a thick white patch of universal veil tissue, membranous partial veil, and saccate volva.
