Sunny Side Fungi is a small, community-focused mushroom business based in Costa Mesa, California. We partner with trusted California farms to source high-quality, USDA Certified Organic mushrooms and bring them directly to our customers through local farmers markets and our online shop.

Our products include fresh gourmet mushrooms, whole dried mushrooms, individual mushroom powders, small-batch ritual blends, tinctures, seasonings, and handcrafted dried citrus. Everything is thoughtfully selected, prepared, and packaged with a focus on quality, simplicity, and everyday usefulness—whether you’re creating a nourishing daily ritual or adding rich mushroom flavor to your favorite meal.

You can find us every Saturday at the Torrance Farmers Market and every Sunday at the Hollywood Farmers Market. We’re proud to support local growers, share approachable ways to enjoy mushrooms, and build genuine connections with the communities we serve.

Our mission is simple: make high-quality mushrooms accessible while supporting California’s local growers and artisans. From market baskets to chef’s tables, we celebrate the flavor, nutrition, and artistry of fungi — always Sunny Side up.
