Two mushroom poisoning incidents in Ningxia, China, were traced to Panaeolus subbalteatus mushrooms. Symptoms appeared about half an hour after eating large amounts, including nausea, vomiting, numbness, dizziness, and disorientation. The mushrooms were identified by morphology and DNA analysis. Psilocybin and psilocin were found in the mushrooms, averaging 1532.2-1760.7 mg/kg and 114.5-136.0 mg/kg respectively. Only psilocin was detected in patients' blood and urine, at average concentrations of 0.5-1.2 ng/mL and 2.5-3.1 ng/mL. These findings can help manage future poisonings.
