Bjerkandera adusta



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



Piptoporus betulinusWhiteoporus     Tribe
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)


Bjerkandera adustaBjerkandera     Genus
All grey to dark grey pore surfaces go here, but pore surface may also be buff to smoky grey
Cap surface creamy to greyish and velvety to hairy when young
Fruiting bodies flexible, sessile, effused-reflexed, sometimes resupinate, often in imbricate clusters
Causes a white rot in hardwoods (rarely on conifers)
