Hi Gordon,

I cannot recall whether the birch was dead, or not. Based on the pictures, my best guess would be that it was.

I was not leaning towards Piptoporus spp., though – their morphologies are slightly different, or so it seems... I am considering Fomes fomentarius. What do you think?

Was the birch it was growing on dead? I think what you have here is one of the polypores, possibly Piptoporus betulinus. Take a look at http://www.mushroomexpert.com/piptoporus... and see what you think.
