A family of wood‑rotting fungi producing gelatinous to leathery fruitbodies, often ear‑shaped or crust-like, found on dead wood in forests worldwide. Surfaces may be smooth, veined, or wrinkled, and colours range from pale brown to dark chocolate. Microscopically, they have septate basidia and sausage‑shaped spores. They play an important role in decomposing wood, and several species are edible and widely cultivated.
