I realise that this is old, indeed I know it’s been there a long time as others here have passed comment on it. I have had an attempt at an identification but really not got far. Any guide in the right direction would be much appreciated. Binscarth Wood, West Mainland, Orkney. It was on a deciduous tree but I forgot to note which species, I suspect Wych Elm, I can go back and check that. Diameter of the largest brackets was about 90mm, photographed last weekend, 21/02/2021.
