Daedalea     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

Daedalea quercinaMaze-o-porus     Tribe
Fungi with a hymenophore of irregular, interweaving plates that divide the space between them into long, twisting chambers and maze-like passageways.
Usually the plates are quite hard and woody, sometimes just tough, never as soft and fragile as the gills on gilled mushrooms

Cerrena unicolorWood-o-maze-o-porus     Subtribe
Top concentrically wrinkled, with the appearance of zoned wood, though perhaps a little bit hairy

Daedalea quercinaDaedaleoporus     SemiTribe
Fruiting body hard, woody

Daedalea     Genus     Persoon: Fries

Daedalea quercina



This is Fries' original genus for taxa with a daedaleoid fertile surface. But most of its species have been transferred out to other genera, so that now only the type species is left in North America

Narrow down your identification:

Daedalea quercinaDaedalea quercina
Fruiting body large (4-10" wide), attachment to substrate broad (often equal to or greater than the distance projecting from the substrate)
Causes a brown heart rot, hollowing out the host
Often on oak
