Notes:
Amanita bisporigera is one of several Amanita species that are known by the common name ‘Destroying Angel.’ Other species are Amanita ocreata (western North American destroying angel) and species in the other eastern North American destroying angels belonging to the Amanita elliptosperma group.
A. bisporigera is differentiated from other eastern destroying angels by the fact that KOH turns yellow on caps of A. bisporigera but not on those of A. elliptosperma group. KOH turns yellow on caps of A. ocreata; this species has a different range from A. bisporigera.
