Do Not Pick or Eat Wild Mushrooms

Recent rain has contributed to the widespread growth of deadly death cap mushrooms throughout California, including San Mateo County Parks. Mushroom foraging is not allowed in our parks and we urge you not to pick and eat any wild mushrooms during this high-risk season.

Poisonous death cap mushrooms, which are easily mistaken for mushrooms that look safe to eat, can cause severe liver damage and death. No amount of cooking, boiling or drying makes these mushrooms safe. These mushrooms are often found near trees such as oaks and pines and also pose a risk to pets that may ingest them while outdoors.

Please inform yourself further about the warnings against mushroom foraging this season by reading the statement from San Mateo County Health in English, Spanish, or Chinese.
