Meet Sunny

Sunny Side Fungi is owned by Sunny Stone and based in Costa Mesa, California. We bring specialty mushrooms and thoughtfully selected pantry products to our community 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 Sunny Stone’s California dried citrus and figs.

We love sharing approachable ways to cook with mushrooms and enjoy them in everyday routines.

Rooted in California

We work with trusted California growers, including Mountain Meadow Mushrooms in Escondido. Our connection to local farms is central to what we bring to the market table.

Our mission is simple: make high-quality mushrooms easy to find while working hand in hand with California’s local growers and artisans. From market baskets to chef’s tables, we celebrate the flavor and artistry of fungi, always Sunny Side up.
