Trichaptum biforme



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


Sessiloporus     Tribe
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


Trametes versicolorSmall Imbricate Polypore     SemiTribe
Fruiting in dense clusters of thin-fleshed shelving fruiting bodies


Purplish-tubed Polypore     SemiHemiTribe
Developing pore surface reddish or purple
Cap white, often furry
Upper context loose and fibrous, except in the most common species :-)


Trichaptum biformeTrichaptum     Genus
Hymenophore and cap margin bright purple when actively growing; fading to lilac or lavender, eventually to buff
Tube walls usually breaking up into a daedaleoid or (more often) toothlike formation
Fruiting body clearly duplex: lower layer denser and darker than the upper layer

Here are the characters that distinguish this species from the others in its group. For its more general characters, see higher up on the page.
If there's just a few words or a microscopic feature here, a more thorough description can be found above.
