The toxin in the death angel is a relatively small protein of eight amino acids, a cyclopeptide called alpha-amanitin. [1], Destroying angels are characterized by having a white stalk and gills. The fatality rate from ingesting amatoxins is around 50% if untreated and still 10% with treatment. These types of mushrooms are nicknamed LBMs, or "little brown mushrooms".
