Abortiporus     Genus

Cortinarius husseyiKey to Gilled Mushrooms     Key
This is a key to gilled mushrooms, that is, mushrooms having a definite cap with a fertile surface consisting of gills. The fruiting body usually also has a stem, although that may be lateral or absent (usually, then, the mushroom is growing from wood). You can use this key to identify mushrooms that you find.

Fomes fomentariusPolyporaceae     Family
Fertile surface usually a layer of vertical tubes, of which the mouths are visible as pores on the underside of the cap or shelf.
Fruiting bodies usually tougher or harder than the "normal" gilled mushrooms, being leathery, corky, or woody. But they can be quite tender while actively growing
Once grown, they do not decay easily, remaining on the substrate for months or years
They often grow on wood, although a few are terrestrial (even those are usually growing on buried wood)
Fruiting body is usually a flat shelf, or hoof-shaped, protruding directly from the substrate, although sometimes it may have a short stalk.
Some forms never grow away from the substrate at all, so that all that is visible of the fruiting body are the pores.
Sometimes the pores are so minute that the fertile surface seems solid, until you look closely

Phellinus ignariusLignicopolypore     Subfamily
Growing on wood

Pycnoporus cinnabarinusRed Polypore     Tribe
The pores red, pink, or orange-red, or the cap at least partially one of those colors

Red Cap Polypore     Subtribe
Pycnoporus cinnabarinus
Cap at least partly red, pink or red-orange
Pore surface white to pale buff, but may discolor reddish

Abortiporus biennis


Microscropic Characters

Narrow down your identification:

Abortiporus biennisAbortiporus biennis
Frequently contorted, twisted, etc, and thus totally variable in shape; in particular, it can have pores on just about any part of the fruiting body
Cap up to 9" across; greyish cream to pinkish tan, sometimes reddening when handled; usually hairy
Stalk usually tapering from a wide base upward;
As with many polypores, it can develop in a rosette from a stalk when growing straight up from its substrate, or in a sessile shelf when growing out sideways; it also grows in a capless form which basically looks like a finger covered with pores, and one shaped like a shoehorn.
