wood ear mushrooms

Wood ear mushrooms (Auricularia auricula-judae), also known as black fungus, tree ear, or cloud ear, are gelatinous fungi that grow on decaying hardwood, particularly elder and other trees. Native to Asia, these mushrooms are characterized by their thin, rubbery, translucent dark brown to black fruiting bodies that resemble a human ear clinging to wood or bark. The surface is smooth to finely wrinkled, while the underside typically bears fine ridges. They have minimal flavor of their own, but are prized for their crunchy yet gelatinous texture and ability to absorb surrounding flavors.

Fresh wood ear mushrooms are tender and delicate, while dried specimens require rehydration in warm water, during which they expand considerably and develop a more pronounced chewy texture. The texture transformation during cooking—from firm to tender—makes them particularly valued in Asian cuisines.

Wood ear mushrooms are extensively used throughout East and Southeast Asian cuisines, particularly in Chinese, Vietnamese, and Korean cooking. They are a classic component of hot and sour soup, stir-fries, and cold noodle dishes, where their distinctive bouncy texture provides contrast to other ingredients. The mushrooms are often paired with garlic, soy sauce, ginger, and sesame oil in stir-fries, or added to soups, braised dishes, and medicinal broths.

Their nearly neutral flavor and ability to absorb surrounding seasonings make them ideal for absorbing rich stocks and spice blends. In addition to savory dishes, they appear in vegetarian preparations and are sometimes used in fusion cuisine for their textural qualities. Preparation typically involves soaking dried specimens until pliable, then slicing or shredding before cooking.
