Welcome to What The Fungus, an Demeter certified specialty mushroom farm located in the heart of West Sussex. We are passionate about growing the highest quality biodynamic mushrooms and sharing our love for all things fungi with the local community.

​

Our journey began with a love for foraging and a deep respect for nature. We started by supplying wild mushrooms to local shops and restaurants, and eventually grew to become the highest quality Demeter certified mushroom farmers in Sussex.

​

At What The Fungus, we believe that good food starts with a connection to the land and the people who grow it. That's why we are committed to sustainable and ethical practices, and take pride in hand-picking every mushroom to ensure it meets our high standards of quality.

​

We offer a wide variety of gourmet mushrooms, including shiitake, oyster, and Lions Mane mushrooms, as well as mushroom grow kits, and educational workshops. In addition, we now offer delivery services, so you can enjoy our delicious mushrooms from the comfort of your own home.

​

Whether you're a chef looking for the freshest ingredients, a food lover seeking a healthy alternative, or someone looking to learn more about sustainable agriculture, What The Fungus has something for everyone.

​

Thank you for visiting our website, and we look forward to sharing our love for mushrooms with you!
