Took along a folding stool to get a more steady shots. Hope these will give more sharp and detail look of the lichen community on the log.
Thank you for following up David and for your dedication! - X. parietina clearly in shot #3 - Shot #2 has again the presumably-Lecanoras and the possibly-Buellias and the other crustose lichens ... I'm also looking at the ones in a sort of row at the bottom, which might possibly be Lecanora xylophila: Match for habitat and colour, tho a bit small perhaps.
Lecanora xylophila ? Are you referring to the tiny brownish ones with white rim ? There are much bigger brownish ones just above, but with no white rims.
Yep the brown ones with paler rims might be L. xylophila. The brown ones above them with less pronounced margins appear to be something different.
