Methods Epidemiological investigation, morphological and phylogenetic identification, and laboratory testing were taken to analyze the poisoning event. Results All the three cases complained of abdominal pain, vomiting and diarrhea after ingesting the poisonous mushrooms, and liver function impairment was found later. One case died after 5 days.
