polyporoids

Polyporoids are a diverse group of fungi belonging to the order Polyporales. These fungi are commonly known as polypores, bracket fungi, or conks. A defining characteristic of most polyporoids is the presence of pores on the underside of their fruiting bodies, which serve as the hymenium, the spore-producing surface. This differs from many other gilled fungi. Their fruiting bodies can vary greatly in size, shape, and texture, ranging from thin and leathery to hard and woody.

Polyporoids are primarily saprotrophic, meaning they obtain nutrients by decomposing dead organic matter, particularly wood. This ecological role makes them important decomposers in forest ecosystems, recycling nutrients and breaking down dead trees. Some species can also be parasitic, infecting living trees and causing wood rot. Their economic importance is multifaceted; while some cause significant damage to timber and lumber, others are valued for their medicinal properties or are used in traditional practices. Identification of polyporoids often relies on macroscopic features such as the pore surface, context (the internal tissue), and growth habit, alongside microscopic characteristics.
