Summary ²

Omphalotus olivascens, commonly known as the western jack-o'-lantern mushroom, is an orange to brown-colored gilled mushroom native to California and Mexico. To an untrained eye, O. olivascens appears similar to some chanterelles, but unlike the chanterelle, the jack o'lantern mushroom is poisonous. While not lethal, consuming this mushroom leads to very severe cramps, vomiting, and diarrhea.
