Oyster mushrooms are medium to large in size with caps averaging 5-25 centimeters in diameter and a very short or non-existent stem. The caps are broad and fan-like, ranging in colour from dark gray, brown, tan, pink, to yellow, and have curled edges that become wavy and lobed with maturity.

Famously used in pizzas, pastas, soups, and lasagne. They are popularly used in many Japanese, Korean, and Chinese cuisine.
