Schizophyllum commune is a species of fungus in the genus Schizophyllum. The mushroom resembles undulating waves of tightly packed corals or loose Chinese fan. "Gillies" or "split gills" vary from creamy yellow to pale white in colour. The cap is small, 1–4 cm wide with a dense yet spongey body texture. It is known as the split-gill mushroom because of the unique longitudinally divided nature of the "gills" on the underside of the cap. It is the only known fungus capable of retracting by movement. This mushroom is found throughout the world.
