white or yellow-white collar that is somewhat similar to the collar seen in the exannulate Amanita albocreata, which is a species of the hardwood-hemlock (Tsuga) forest of the northeastern U.S. and southeastern Canada and of boreal forest at least as far north as the Island of Newfoundland. The clamps present at bases of basidia of this species specially support the presumed relationship to Amanita muscaria var. muscaria or simply Amanita muscaria. Amanita muscaria is a poisonous and psychoactive basidiomycete fungus, one of many in the genus Amanita. Many misidentifications have taken place while recognizing Amanita flavoconia, one of the most common and widespread species of Amanita in eastern North America, due to various similar physical characteristics. It is mostly confused due to their microscopic features. Edibility The species is considered inedible and poisonous.
