polyporus

Polyporus is a genus of fungi in the family Polyporaceae. These fungi are commonly known as polypores or bracket fungi. They are characterized by their pore-bearing undersides, where basidiospores are produced. Many species of Polyporus are saprophytic, meaning they feed on dead organic matter, particularly wood. This role makes them important decomposers in forest ecosystems, helping to recycle nutrients.

Species within the Polyporus genus vary in size, shape, and color, though many are tough and leathery or woody in texture. They often grow on tree stumps, fallen logs, or living trees. Some species are economically important as sources of food or traditional medicine, though identification is crucial as many fungi can be toxic. Common examples include Polyporus squamosus, known for its large size and scaly cap, and Polyporus badius. The genus is found worldwide. Research into Polyporus continues to explore their ecological roles, potential medicinal properties, and genetic diversity.
