Just guessing based on overall appearance…

You can verify the ID by checking for:

1. is it pruinose or dusty-looking all over?
2. does it have bottle-brush-like black rhizines (rootlets) underneath (may need a hand-lens)
3. is it breaking down into little granules around the margin

If yes on all three then definitely P. detersa. Another possibility might be Phaeophyscia. (Might be worth checking that it’s not yellowish, orangish or reddish inside if you scratch the surface cortex off.)
