Hi Bruce, excellent close-ups, though in this case a view of the whole lichen would have been good too. It is often useful in this genus to see the edge of the colony and to see the arrangement of the apothecia.

However, taking into account the habitat, this is undoubtedly Lecanora campestris - a common species on concrete.

Thanks for your help Alan. I'll take your advice and try to get a pic of the complete lichen in future.
