Found this on the Barnhardt Trail in the Mazatzal Wilderness today. Central Arizona, Gila County. 4000-4400 ft elev.
What is it?
Fungi found today
Close-up
It's an unusual polypore.
You should try to locate the local fungus expert to figure the species.
Can you show more details of the growth. Any more photos!
These two are my only photos. Just for Information sake, this is in the Tonto National Forest boundries.
I'm going to search on-line a bit for this also
Could it be Ganoderma applanatum (Bracket Shelf Fungi)?

It reminds me of Trametes versicolor - one of the turkey tail types. However, most of the Trametes I have seen are darker on the non porous side. You might Google that name, then click on "images" - and snoop through the long series of photos.
