If you eat a deadly Amanita like this western species, Amanita ocreata, be prepared for a 4-stage poisoning. Stage I will be a 6-24 hour latent period when the toxin gets into your system but doesn't yet let you know that you have been poisoned. Typically after 10-14 hours stage 2 begins and is marked by sharp abdominal pains, nausea, vomiting and watery diarrhea. Stage 3 is marked by a brief remission lasting about 24 hours. You and your doctor think that you are on the road to recovery, but during this period medical attention is most important. In stage 4, symptoms recur along with jaundice, liver and kidney failure, convulsions and coma. Unless a large meal of the mushrooms has been consumed, there is a 95% survival with supportive care, 50% mortality if untreated. Death usually occurs in 4-7 days. Recovery with good medical care can take over two weeks and liver function may be permanently impaired. Liver transplants are at times called for. Amanita ocreata is easily confused with the white variant of an Amanita known commonly as Coccora, a choice edible.
