Favolus     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

Favolus     Genus     P. de Beauvois: Fries

Favolus alveolaris



There's another genus of polypore, Hexagona, that has even larger, distinctly hexagonal pores. It looks like a honeycomb from beneath
It is a tropical species, found only along the gulf coast in the US, and so is not included in this database. I have no idea, by the way, why R. L. Gilbertson & Ryvarden (1986 - 1987) spell it "Hexagonia"
Most authors nowadays reduce Favolus to a section of the genus Polyporus. It doesn't really matter which way you do it; the only thing it changes is whether you hit Favolus before or after Polyporus in your key

Cap creamy tan with a darker, reddish-brown layer on top of it that breaks up into scales; often slightly lobed
