Auricularia Auricula Judae

Auricularia auricula-judae, commonly known as the Wood Ear, Jelly Ear, or Black Fungus, is a gelatinous, ear-shaped mushroom widely used in Asian cuisine and traditional medicine. It grows on decaying wood, especially elder trees, and is prized for its crunchy texture, mild flavor, and health-promoting properties. Often rehydrated from its dried form, it’s commonly found in Chinese stir-fries, soups, and salads.

History

The name “auricula-judae” ("Judas' ear") stems from European folklore that it grew on the elder tree where Judas Iscariot supposedly hanged himself. In Asia, however, it has a long and respected history in Chinese and Japanese medicine, where it is known for promoting circulation, reducing cholesterol, and supporting overall vitality.

It has been cultivated for centuries in China and is one of the oldest domesticated mushrooms. Today, it remains a staple in Chinese, Thai, and Vietnamese dishes, often appreciated more for texture than taste.

Overview

The Wood Ear mushroom has a rubbery, gelatinous texture and an ear-like shape. It ranges in color from brown to black and grows in clusters on dead hardwood, especially elder, beech, or sycamore. It can grow year-round in humid climates.

Culinarily, it is mild but valued for its crunch. It's low in calories and high in fiber, iron, and antioxidants. Medicinally, it is believed to improve blood health, reduce inflammation, and support immune function. It is almost always eaten cooked and is frequently sold dried for long shelf life and convenience.
