wood fungus

Wood fungus, commonly known as cloud ear fungus or tree ear fungus (Auricularia auricula-judae and related Auricularia species), is a gelatinous fungus that grows on decaying wood, particularly elder and other hardwood trees. Native to Asia and now cultivated worldwide, wood fungus has a thin, ear-like fruiting body that ranges from dark brown to black in color. The texture is rubbery and gelatinous when cooked, with a subtle, slightly earthy flavor. The fungus is prized as much for its distinctive texture and ability to absorb flavors as for its nutritional properties. When dried, it shrinks dramatically and becomes brittle; upon rehydration, it expands to several times its original size.

Auricularia species have been used in traditional Chinese medicine and cuisine for centuries, valued for their cooling properties and use in treating various ailments. Different cultivars and related species (such as wood ear and jelly ear) offer slight variations in thickness, color, and texture.

Wood fungus is widely used in East and Southeast Asian cuisines, particularly Chinese, Vietnamese, and Korean cooking. It appears in stir-fries, soups, hot pots, and braised dishes, where its gelatinous texture provides a delicate contrast to other ingredients. The fungus is prized for its ability to absorb sauces and complementary flavors while maintaining its distinctive crunchy-yet-tender bite. In Chinese cuisine, it frequently appears in Buddha jumps over the wall (fotiaoqiang), cold appetizers, and vegetarian dishes. Wood fungus is also used in dim sum preparations and as a nutritious addition to medicinal soups. It pairs well with mushrooms, vegetables, and seafood, and its neutral flavor makes it adaptable to both savory and slightly sweet preparations.
