Trametes     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

Not fitting the other choices, not stipitate
In making choices below based on texture and size, place the emphasis on texture: if left alone, some of the smaller ones can eventually get quite big; and even the huge ones have to start out small at first

Trametes suaveolensSmall Sessilopolypore     Subtribe
Individual caps small (max. 2-3" across)
Soft or tough, but not hard when fresh, although they may become hard when they dry out
All thin-fleshed fruiting bodies go here, especially if compound or imbricate

Small Imbricate Polypore     SemiTribe
Trametes versicolor
Fruiting in dense clusters of thin-fleshed shelving fruiting bodies
Links from Look-alikes
Whiteoporus     Tribe
Piptoporus betulinus
Sessile cap entirely white to buff
Pores concolorous or yellow or pale grey, sometimes darkening in age to grey or even black
Sometimes with moss or algae growing on the cap (coloring it green)

Microscropic Characters

Trametes versicolor



This genus is extremely hard to characterize as a whole in macroscopic terms. If you're not going to do microscopic work to check the features that truly define it, it's best to think of it as the sum of its two sections
The type of this genus is Trametes suaveolens, which is a Scandinavian fungus (also found here) with a strong, sweet smell of anise. Fries reported that teen-age boys in Lapland would put the fungus in their clothes to give them a nice smell and render them more attractive to women
