I took this pic when out on a stroll yesterday.

I believe it's Birch polypore - but is the 'dust' its spore?

Its not Birch Polypore. Is it many zoned polypore/turkey tail fungus, but it usually has a more banded appearance?
Birch Polypore is a lot thicker, looks and feels like polystyrene.

I don't thinks so. I'd ruled it out as the description in my book describes Many-zoned Polypore as 2-7 cm across, 2-5 cm broad and 1-5 mm thick. If it was inches rather than centimeters I'd say it would be more of a possibility.

The black dust looks like bug scat, the white dust looks like broken down fungi. Spore dust is very fine, custard powder like which is white for most polypores.

As to what it is, is another matter. My best guess is coriolus hirsutus, I am sure it is not birch polypore. there are quite a few very simerlar fungi and I am guessing.

Thanks for all of your help.
I don't think it's Coriolus hirsutus as I'd have thought 'Blimey! A hairy mushroom?' when I found it. I really think it'd be a good idea if I carried my books when I go walk-abouts instead of relying on my camera.
I think I may have finally I.d'd the fungus. I think it's Hump-backed Polypore (Pseudotrametes gibbosa) - the size is correct as is the books description 'Old specimens become browner and are frequently green in the middle from encrusted algae' and although it doesn't show in the pics the fungus was 'lumpy and bumpy' - I'd thought they were caused by damage and didn't mention them.

Again, thanks for your help and thanks for disagreeing with me too :D
