About the name

Amanita virosa is a name of European origin that has been widely applied to white North American amanitas. Mexican literature records Amanita bisporigera, Amanita verna, and Amanita virosa in Sonora as species that cause phalloid poisoning; no poisoning cases are known in that state. These uses of the name require care when comparing records.[3][10]

  • Amanitin has been detected in the cap, gills, stem, and universal veil.[12]
