Went for a bimble under the Forth Road bridge, where I know there are a few young and older birch trees.
Found three fine specimens of birch polypore about the size of a 3 egg Omelette.
Having got home I checked my Collins Complete British Wildlife Guide to confirm - ding dong!!!
Now I know for definate that's what they are, I'll harvest them tomorrow.
Do they need any special prep'?, I intend to add them to my fire kit for one thing.
I'll gather more red papery birch bark curlings as well.
Thanks in advance.

EDIT; I used the search function and have found the answer on other birch polpore threads.
