Never heard of this one… exciting!

“…in compact [distinct] patches of convex or swollen areoles… sometimes almost lobe-like and notched at margins, starkly white or rarely pale grey, surface slightly rough to granular… apothecia abundant, generally compacted in the center…disc pale pink- to yellow-brown or olivaceous…” Claims all tests are negative, but lists dichlorolichexanthone (UV+y), and sometimes pannarin (P+r) in non-British material.

So it’s the “swollen” areoles and pale color that give it away?
