I would go with X. plittii, although I notice now that I look that there are quite a few with black lower surface with stictic acid. Fool that I am, I didn’t request a shot of the lower surface!

[EDIT: Oops! I didn’t see the photo at the bottom. Yes, definitely plittii, then.]

Should be able to ID once we know the result of the K test.
