polypora

Polypora is a genus of fungi in the family Polyporaceae. It is characterized by its polypore fruiting bodies, which are typically large, flat, and fan-shaped. These fungi are commonly known as shelf fungi or bracket fungi. Polypora species are found worldwide, growing on dead wood, particularly hardwoods, and are often associated with deciduous forests. The genus includes several well-known species, such as Polyporus squamosus, which is commonly found in North America, and Polyporus umbellatus, which is more widespread in Europe.

The fruiting bodies of Polypora species are typically brown to gray in color and have a smooth or slightly textured surface. They are often found growing in clusters or in groups, and can reach significant sizes, sometimes exceeding a meter in diameter. The underside of the fruiting body is typically white or cream-colored and is where the spores are produced.

Polypora fungi play an important role in the ecosystem by breaking down dead wood, which helps to recycle nutrients and create habitats for other organisms. They are also of interest to mycologists due to their distinctive appearance and the potential for new species to be discovered.

In cultivation, Polypora species are relatively easy to grow and can be found in many mushroom cultivation kits. They are often grown on sawdust or other wood-based substrates and require a warm, humid environment to thrive.
