Viess said field reports coming into her organization suggest the growth of death caps may be slowing in the Bay Area, while another kind of poisonous mushroom known as the destroying angel, or Amanita ocreata, is starting to pop up.
A. ocreata is highly toxic, and has been responsible for mushroom poisonings in western North America, particularly in the spring. It contains highly toxic amatoxins, as well as phallotoxins, a feature shared with the closely related death cap (A. phalloides), half a cap of which can be enough to kill a human, and other species known as destroying angels.[3][14] There is some evidence it may be the most toxic of all the North American phalloideae, as a higher proportion of people consuming it had organ damage and 40% perished.[15]
Oh, great.
