Stereum and Trametes

are both hairy/fuzzy according to M. Kuo: Kuo, M. (2008, December). Stereum ostrea. Retrieved from the MushroomExpert.Com Web site: Trametes has pores; Stereum does not.

can’t make enough detail out. Can see lots of hairs. But hair can be from Trametes versicolor or Trametes hirsutum, for example. BTW, I suspect this could as easily be Trametes as Stereum.

Photo of Underside

The photo with the hand has two pieces of the fungi. The top most piece is actually flipped over and does expose the underside.

Other things that would help identify this:

Being sure to identify the host tree (birch in this case), and a photo of the underside (hymenium) where the spores are produced. You wouldn’t expect to get an identity of a blueberry without a blueberry, would you? ;) (Actually, a whortleberry would be more likely in your area.)

BTW, Stereum and Trametes are both thin-fleshed, and used as medicine in China. Try chewing a piece of it like gum (it’s safe). The Chinese often use this for aspirin.
