“…Amanita phalloides is the most toxic amatoxin -containing mushroom species with an amatoxin content of about 2 -3 mg/g dry tissue. 42 Some American samples of A. virosa contain relatively small amounts of amatoxin, but relatively large concentrations of virotoxins, whereas some European specimens contain amatoxin concentrations similar to local specimens of A. phalloides . A study of three Amanita phalloides specimens demonstrated the highest amatoxin content in the ring, gills, and cap, whereas the bulb and volva contained smaller amatoxin concentrations and larger concentrations of phallotoxins.…”
