Notes on Taxonomy: [Edit]

This name is a valid name for a most unusual fungus that ranges northward from the central Appalachians to the tree limit in Canada and beyond. It can occur in subarctic and boreal coastal heaths with blueberries. It has once been reported from a field of cultivated blueberries. A very odd symbiont for an Amanita! See the Amanita wellsii page of the Amanitaceae Studies web site. RET
