Trametes versicolor - Turkeytail Phylum: Basidiomycota - Class: Agaricomycetes - Order: Polyporales - Family: Polyporaceae

Pores on white underside.

Trametes versicolor, Turkeytail fungus can be found all through the year, but it is most obvious in the winter months when deciduous trees are bare. This very variable fungus grows mainly on dead hardwood, including stumps and standing dead trees as well as fallen branches. Some specimens are strikingly vivid in their coloring.

This thin, leathery fungus attacks mainly dead wood, fallen or standing. It is most commonly found on hardwoods such as beech and oak, mainly as a saprobic (wood-rotting) fungus but sometimes as a weak parasite on living trees.

Several corticioid fungi (crusts) can produce zonate fruitbodies; among them are Stereum species, which differ from Trametes in having smooth spore-bearing undersides rather than having pores.
See Stereum subtomentosum for example.
