Stony Stratford, Bucks. On same stone as "orange peel" lichen (Protoblastenia rupestris).

Help with identification appreciated as always:

Hi Bruce,

usually, when I try to name lichen photographs on this site I complain (or at least mutter to myself) that we don't have a close enough or clear enough view to see essential surface details. After all, we are trying to identify species for which a hand-lens would often be employed in the field.

Here we have the opposite, excellent close-up detail, but no context, no view of the whole lichen thallus.

I have a feeling about this one, probably a Lecanora, but without seeing the whole colony, especially the edge, I cannot safely suggest a name. [I suspect that in this case, the edge is distinctly lobed.]

Thanks Alan - I appreciate your advice and will make sure I include a whole-colony pic as well as close-ups in future.

As far as this post is concerned, I will try and locate the same colony and take some more pics. Meanwhile here's a photo that just shows the edge. I didn't post it originally because I wasn't too happy with the quality:
