I may catch some flack for using this name but since Rod Tulloss is now using it on his site and since in 99 out of a 100 times, one can easily distinguish this from Amanita calyptroderma, both visually and by habitat/season, why not start separating the two species? These were found at about 3600 Ft. with mostly small pines nearby. The spores in this case were measured in a combination of KOH and Congo Red. 16 spores ~ 11.1-15.0 X 8.0-11.2 microns.
