P. laevigatus

is my guess, only because I don’t know what else it could be..
It is found mainly on birch and the pore surface turns grey rather soon when it’s aging – but hardly violet (sky reflection..?). Phellinus punctatus has less marked margins. If it is possible to check some details in the scope and use a Phellinus key, look for hymenial and tramal setae (some have them, some haven’t), spore size and shape. Some have dextrinoid spores, some haven’t.

Thats why I wonder about Irene’s suggestion as well. Also why when I looked at the first picture on my iphone it reminded me of H tortisporum (sp?) because of the shape and coloring.

Yes, I added the second picture after your proposal.

I suppose this could be Phellinus punctatus, or possibly more likely P. laevigatus, but what puzzles me is the violet grey color. I don’t find that in the descriptions.

are you going with this name just because of host, or is there something else you commonly see with species?

Did you add that 2nd picture

after my name proposal or was it there originally? Maybe Phellinus punctatus?

This appears to be a polypore.
