in Bolivia. once the digital darkroom train gets chugging, it will make its way here. one of the most beautiful Amanitas I’ve ever seen, much less collected.

There are one or more yellow species of subsect. Vittadiniae in the Americas.

This/these stretch from Florida and the Caribbean region to Brazil…at least. The name A. aureofloccosa Bas has been applied; however, this material was described from Africa and belongs in a group that lacks clamp connections at the base of the basidia (Bas’ stirps Thiersii). The yellow material that I have examined from Florida and Mexico has clamp connections at the bases of basidia and, therefore, can be assigned to Bas’ stirps Nauseosa. My provisional name (not on WAO) for the yellow species with which I am familiar is “aureosylvatica.”

All known species of both stirps Thiersii and stirps Nauseosa are “free-living”—they do not form mycorrhizae with plants and can digest cellulose (dead plant matter) or the products of partial digestion of cellulose by other organisms.

Very best,
