Amanita pantherina and Amanita pantherinoides, shown here, are look-alikes distinguished from Amanita muscaria by having a single roll of tissue looking like a stand-up collar at the base of the stem just above the bulbous swelling. Amanita pantherina causes more mushroom poisonings than any other mushroom in the Pacific Northwest. It first appears in the spring and can fruit well into the fall months. It is large, meaty and attractive with a delicious flavor. Children, dogs and cats all eat it as do adults who mistake it for an edible species and adults who eat it for the mind-altering effects. It causes a more violent poisoning than Amanita muscaria. One problem that seekers of hallucinogenic plants face is that the content of active ingredients varies from one region to the next and from one specimen to the next. Unlike the Psilocybe species where there is a wide range of mushroom that can be consumed without serious side effects, with both Amanita muscaria and Amanita pantherina there is little difference between the amount of mushroom that will produce little or no mind-altering effect and the amount that produces violent convulsions or a deep coma-like sleep.
