The cup fungi (Peziza) are a large group of fungi that grow on or around rotting wood. They tend to grow in clusters. Their name is derived from the Latin word for foot -- as they lack a stalk.
While it was once thought that they were decomposers, it now appears that they may play a part in symbiotic relationships with certain trees.
Determining individual species of cup mushrooms requires input from a cup mushroom expert.
