Split Gill Mushroom
Schizophyllum commune
Schizophyllum commune is one of the most widely distributed mushrooms on Earth, turning up on fallen branches and dead wood on nearly every continent. Its small, fan-shaped, velvety gray caps have long been gathered as food in parts of Mexico, West Africa, and Northeast India, where the tough little mushroom is simmered into soups and stews until it softens. In Japan, a polysaccharide isolated from its fruiting body, called schizophyllan, was developed into a licensed pharmaceutical used alongside conventional cancer treatment to support the immune system, a modern echo of the mushroom's older folk reputation as a strengthening food. Because it dries to a papery husk and springs back to life the moment rain returns, it has also earned a quiet place in folk memory as a small emblem of endurance.

Traditional preparations.
In parts of Mexico, West Africa, and Northeast India, dried split gill mushrooms are traditionally softened in broth as a humble, nourishing addition to everyday soups.
Traditionally, a small handful of dried caps (about 5 to 6) is simmered in 2 cups of broth or water for 15 to 20 minutes, until the tough gills soften, then eaten as part of the soup.
Safety.
Split gill mushroom is eaten as food in parts of Mexico, West Africa, and Northeast India, but it's tough and fibrous and must be cooked thoroughly. People who are immunocompromised or have chronic lung conditions should avoid handling or foraging it, since it has rarely been linked to opportunistic lung and sinus infections.
