Lepiota josserandii is one of several small Lepiota species that have lethal levels of amatoxins. This species is not uncommon in California in the spring under live oak and shrubbery. One deadly poisoning occurred from Lepiota josserandii picked in New York under Scott's Pine. The victim, a very experienced mushroomer, thought that he was eating Lepiota excoriata and knew of no reports of poisonous Lepiota species in New York. The highly similar, if not identical, Lepiota subincarnata has more recently caused a fatality in British Columbia. Since the edibility of many mushrooms is not well determined and since identifications of many of the poisonous mushrooms can be difficult, it is hoped that doctors involved in treating mushroom poisonings would promptly seek the help of trained mushroom identifiers. Not only can these individuals often help in spotting potentially lethal mushrooms, but identifications by trained mycologists can help us better determine which species of mushrooms are causing trouble and help educate other mushroom pickers.
