  Polypore - Wikipedia, the free encyclopedia
Polypores are a group of tough, leathery poroid mushrooms similar to boletes, but typically lacking a distinct stalk.
The technical distinction between the two types of mushrooms is that polypores do not have the spore bearing tissue continuous along the entire underside of the mushroom.
Polypores are often found on rotting logs, and are rot-resistant to the extent that they themselves often last long enough to have moss growing on them.

 Naming the Polypores: Why Polyporus has been split up into more than 100 genera
Polypores (family Polyporaceae and similar fungi) can be easily distinguished from the other common poroid fungi, the boletes, by their typically hard exterior, their usual "non-mushroom" shape, and their usual growth on wood as wood decomposers.
There are often "sister" genera in the polypores, with seemingly identical characters, except that one causes a white rot and one causes a brown rot.
One common polypore with cystidia is the purple parchment fungus, Trichaptum biforme.

Polypores and steroid fungi are the best known groups of wood-inhabiting fungi.
The aim of the project is to generate new knowledge of ecology and natural history of tropical polypores and steroid fungi.
I have collected polypores and steroid fungi in four tropical forests; primary and secondary dry forest, pre-montane wet forest/cloud forest, and Caribbean slope rainforest.

 Polyporales: The Polypores (MushroomExpert.Com)
Most of these are "polypores" in the widely used sense of the word: they are wood decomposers whose spores are held in tubes (rather like the tubes of the boletes).
Current DNA studies shift the polypores around on what seems like a daily basis, and a few have been moved out of the polypore order entirely--like Bondarzewia berkeleyi, which is currently placed in the Russulales.
The pore surface of a polypore is often distinctive; for example, Daedaleopsis confragosa has a maze-like pore surface, easily distinguished from the pore surfaces of the many polypores with tiny, round pores.

Polypore mushrooms are usually hard and are attached to trees.
Polypores as a group are comparatively benign compared to their gilled cousins, many of whom are poisonous.
Polypores are also resplendent with antibacterial compounds and are good for making into a poultice should you get cut and/or get an infection.

 Symposium "Phytogeography of Northeast Asia", abstracts: MUKHIN V.A.   (Site not responding. Last check: 2007-10-20)
In our opinion, analyses of the complexes of polypores associated with the larch species of North Eastern Asian origin (Bobrov, 1972) could be useful for understanding the co-evolution of wood-decaying fungi and woody plants.
The similarity of the polypore assemblages with L. olgensis and North Asian larches is about half (CSS is 0.27- 0.36) of that between the North Eastern Asia and North America.
We suppose that complexes of polypores of North Asian larches consist of species which are adapted to cold and dry climate, i.e., to areas which are occupied by L. cajanderi, L. gmelinii and L. sibirica.

Polypores are the common name given for those fungi with poroid appearance.
It is a hard job identification of polypores, because this kind of fungi is greatly diverse.
We can identify the polypores by dissecting the fungus tissue, the shapes or colors of their spores, or simply by external morphology (although this is not a reasonable method!)

 Ganoderma applanatum, the artist's conk, Tom Volk's Fungus of the Month for March 1999
Ganoderma applanatum is classified as a polypore, which literally means "many pores." The white pores are on the under-surface of the fruiting body.
The Polypores are a fascinating group of fungi, although not usually of interest to most mycophiles because of their typical inedibility, commonly small size, unfamiliar habitat and general obscurity.
Polypores can be easily distinguished from the other common poroid fungi, the boletes, by their typically hard exterior, their usual "non-mushroom" shape, and growth on wood as wood decomposers.

If the macroscopic fungus fruiting body is collected, it may be identified as a polypore (bracket fungus).
The polypores belong to a limited group of fungi capable of attacking wood and using it for food.
The natural habitat of the polypores is wood, i.e., slash in forests.

Currently, we know that there are 223 species of polyporous fungi in Finland, of which 38% are classified as threatened or near threatened.
The decline of polypores is almost completely due to forestry, which causes habitat loss, habitat fragmentation, and habitat degradation.
These species are often habitat-specialists, which means that the substrate tree species, type of tree (downed log, standing snag etc.), size of substrate, decay stage, microclimate, and biotic circumstances matter.

A few polypores do not form brackets and are mushroom-like, with a cap and a central stalk.
Also, in some polypores shelves are lacking and fruitbodies form of a flat layer (resupinate) on the undersurface of a twig or branch.
A few, such as the Rooted Polypore (Polyporus radicatus) colonize buried wood and produce stalked fruitbodies seemingly directly from the ground.

 Types of fungal fruiting bodies
Polypores mostly grow on dead or living wood and (apart from a few mushroom-shaped species) are anything from hoof-shaped to merely thin plates.
Most of the species are from one to 20 centimetres in diameter, but occasionally some species do grow to a metre or more.
Polyporus arcularius is an example of a mushroom-shaped polypore, while Ganoderma australe shows the more common, bracket-like growth form.

 Fungal spore dispersal
Gill fungi, boletes and polypores all have their spore producing surfaces on the undersurface of the fruiting bodies, so that the spores drop out into air currents below.
This is done by collecting the fruiting bodies of fungi such as gill fungi, boletes or polypores and placing the cap or spore producing surface onto a piece of paper.
The print at left is from a gill fungus and clearly shows the arrangement of the gills which carried the spores.

The prefire fungal flora (polypores and corticoid fungi) of 284 dead trees, mainly fallen trunks of Norway spruce (Picea abies), was studied in 1991 in an old, spruce-dominated mesic forest in southern Finland.
In 1992 part of the study area (7.3 ha) was clear-cut and a 1.7 ha forest stand in the center of study area was left standing with a tree volume of 150 m3/ha, and later on (June 1st) in the same year the whole area was burned.
No fruitbodies of threatened polypores or other ‘old-forest species’ of polypores were found again after fire.
