The Wood Ear mushroom is also known as a Judas' Ear and Tree Ear mushroom. It gets the name “wood ear” because it resembles a large ear when it is fresh and can grow as large as half a foot! The caps of the mushroom are purplish-gray in color and the flesh is a dark purplish gray to almost black in color. They have very little flavor, but are mainly used for their firm, gelatinous texture and for their color. They are mainly used in Asian cooking and are even believed to have medicinal benefits! You can purchase dried pieces of this fungus variety at most Chinese markets. When ready to use, soak or simmer them in hot water for about 15-20 minutes until they soften. Tastes great in pastas, soups, or seafood dishes!
