Polypores are a group of fungi that form fruiting bodies with pores or tubes on the underside (see Delimitation for exceptions). They are a morphological group of basidiomycetes like gilled mushrooms and hydnoid fungi, and not all polypores are closely related to each other. Polypores are also called bracket fungi, and their woody fruiting bodies are called conks.
Most polypores inhabit tree trunks or branches consuming the wood, but some soil-inhabiting species form mycorrhiza with trees. Polypores and their relatives corticioid fungi are the most important agents of wood decay. Thus, they play a very significant role in nutrient cycling and carbon dioxide production of forest ecosystems.
Over one thousand polypore species have been described to science,[1] but a large part of the diversity is still unknown even in relatively well-studied temperate areas. Polypores are much more diverse in old natural forests with abundant dead wood than in younger managed forests or plantations. Consequently, a number of species have declined drastically and are under threat of extinction due to logging and deforestation.
Polypores are used in traditional medicine, and they are actively studied for their medicinal value and various industrial applications. Several polypore species are serious pathogens of plantation trees and are major causes of timber spoilage.

From 7/26/1995: Northbound Q376-26 with a YN2 SD50 and a CRL (Conrail Leasing) C30-7 split the intermediate bracket CPL signals at MP 98 at Sidney, Ohio.
Seen from the canal towpath. The log was down a steep slope so I couldn't get to them to take a better picture, so I don't know what they are.
A pair of Conrail trains are about to bracket Berea Tower. The train in the foreground is on the Toledo connection, which was used extensively in the Conrail era to get from the Chicago Line to the Short Line. The train on the north side of the tower is on the Chicago Line. (Scanned from a slide)
Large bracket or shelf fungi are common in mature forests. Some of their fruiting bodies may grow for many years on the trunks of living or dead trees. Their upper surface is leathery or woody. Like the boletes, they have pores on their undersides. When conditions are favourable, those brackets that grow from one year to the next produce a layer of new tubes on their lower surface, from which spores are released.

Went walkabout in the woods for an hour this afternoon and the signs of Autumn are starting to become obvious.!

Shelf fungi are commonly found growing on trees or fallen logs in damp woodlands.

As it exploits the wood, the fungus sends out a hard, durable structure called a conk, which has on its underside tens of thousands of pores.
