Examples include Amanita phalloides (the “death cap”) and Amanita ocreata (the “destroying angel”) species. Amatoxin poisoning results in severe symptoms of gastroenteritis at least 6 to 24 hours after ingestion. Symptoms include nausea, vomiting, profuse watery diarrhea, and abdominal pain. GI symptoms may last 12 to 24 hours and are followed by a latent period of apparent improvement. This period is followed by a rise in liver enzymes and bilirubin. Fulminant hepatic failure and renal failure may become apparent.
