One of the most common forest fungi in North America is the turkey tail (Polyporales: Polyporaceae: Trametes versicolor). Found year-round on decaying hardwood trees and sometimes conifers, this mushroom gets its common name from its colorful, fan-like similarity to the tail of a wild turkey.
Several other fungi also bear a strong resemblance to turkey tails, however. Other species of Trametes as well as the “false turkey tail” (Russulales: Stereaceae: Stereum ostrea) look pretty similar at first glance. They can be distinguished by identification techniques including pore count, spore print, microscopic features, and chemical reactions.
Although fungus identification isn’t really within my realm of experience, I did want to share these interesting photos and basic information for future reference.
