Not Caloplaca teicholyta

The definition isn't good enough for me to make a suggestion as to what the lichen is. (Close examination with a lens needed.)

However, Caloplaca teicholyta has a thicker, less cracked thallus with a more-or-less lobed margin, the surface often with rounded areas producing dark powdery granules (soredia). It is primarily south-eastern, unlikely to be in a Cheshire churchyard (northern records often incorrect).

I'll try and get another

I'll try and get another photo as this one was the most common in the graveyard. It was on pratically every gravestone.

One to consider

There is a familiar look about this thing and it looks like it might have irregular black apothecia with thick, white margins, sunk into the thallus. In which case, Aspicilia caesiocinerea is a distinct possibility. It is often a common species on nutrient-poor ("acid") rocks.
