Edible or Poisonous?

There is no quick and easy test that will separate edible from poisonous mushrooms. Identify each and every mushroom you collect, and only eat those whose identification you are absolutely sure of. When in doubt, throw it out. Seek medical assistance immediately if you suspect mushroom poisoning of any kind.


Any amount of any poisonous mushroom is considered to be very dangerous. Please call the Poison Center immediately at 1-800-222-1222 if anyone ingests any part of a mushroom picked from a yard or the woods that has not been properly identified. If you have any pieces of the actual mushroom that was eaten you will be asked to save it in a brown paper bag. Many mushrooms can look identical but be very different.
