13 Mushrooms to Know About in California

Known as the Golden State, California is an interesting area with diverse landscapes and rich biodiversity. It is filled with a plethora of various flora and fauna, including a wide array of mushrooms. The mushrooms in California range in size, shape, and color, and many of them are safe to consume.

Below you will learn about some of the most common edible, and toxic, mushrooms in California.

Edible Mushrooms in California

Foraging for wild mushrooms in California can be dangerous. While there are many different safe and edible mushrooms found throughout the state, there are several that can pose a risk to your health. That is why it is essential to exercise caution during and after mushroom hunting.

Only consume mushrooms that you can confidently identify. If you’re not certain about a mushroom’s identity, it’s always best to err on the side of caution and just assume it’s not edible. Additionally, consider seeking guidance from a mycologist or another expert in the field of mushrooms.
