Once again found a fungi growing on birch and I'm not entirely sure what it is. It looks quite like the chaga fungi but I'm really not too sure! I have seen chaga in some videos before and it seemed much darker but I don't know anything else it might be. The log was on the ground and quite damp.
Yes it is in lowland scotland, the same general area as my previous question! I had a look around to see what else I could find and this is what I found. It wasn't the same tree, maybe about 40 meters from that one.
