Schizophyllum commune is a species of fungus in the genus Schizophyllum

The caps are 1–4 centimetres (3⁄8–1+5⁄8 in) wide with white or grayish hairs. They grow in shelf-like arrangements, without stalks.[3] The gills, which produce basidiospores on their surface, split when the mushroom dries out, earning this mushroom the common name split gill. It is common in rotting wood.[4] The mushrooms can remain dry for decades and then revived with moisture.[3]
