Roughly 75 people in North America are poisoned each year by mushrooms, often from eating a poisonous species that resembles an edible species. Though deaths are rare, there is no cure short of a liver transplant for severe poisoning. Don’t eat any mushroom unless you are absolutely certain of its identity! Please don’t trust the identifications on this site. We aren’t mushroom experts and we haven’t focused on safely identifying edible species.
