Many mushrooms are poisonous and some are lethally poisonous. It can be very difficult to distinguish between an edible and a poisonous mushroom. Because of that, we strongly advise against consuming wild mushrooms, and this site does not contain any information about the edibility or toxicity of mushrooms.
Although efforts have been made to ensure accuracy on this website, the information may contain errors and omissions. Therefore, the information presented here is for informational purposes only and should not be relied upon as any basis for consuming any plants or mushrooms.
