Wild mushrooms are not a guess-and-cook food
CDPH and California Poison Control warn that wild mushrooms can be hard to identify, and mistakes can be serious even when mushrooms look familiar.
After rain, California parks, yards, and open spaces can sprout mushrooms that look interesting enough to bring home. That does not make them food.
Wild mushroom identification can be tricky, and some dangerous mushrooms look ordinary. Photos, apps, and casual guesses are not enough for dinner. CDPH and California Poison Control both point people toward caution.
The easy household rule is to leave wild mushrooms off the plate unless a truly qualified expert has identified them. This matters for children and pets too. If someone eats an unknown mushroom, save a sample or photo if it is safe, and call Poison Control or emergency help.
