Poisonous mushrooms occur in Sonoma County and it's always a good idea to be cautious when cooking with wild mushrooms. Never eat a wild mushroom unless you're absolutely certain of its identity.
If you think you, your child, or even your dog may have eaten a poisonous mushroom, seek medical attention immediately.
Free EMERGENCY identification service
Because identifying poisonous mushrooms can be tricky, the Sonoma County Mycological Association offers a free identification service to hospitals, veterinarians, and concerned citizens of Sonoma County.
After seeking medical attention, contact Darvin DeShazer for identification.
*Photos should show all sides of the mushroom. Please do not send photos taken with cell phones—the resolution is simply too poor to allow accurate identification.
