I got K+y P+y C- (even in section) KC- UV-. I’m tentatively considering Caloplaca yuchiorum based on James Lendemer’s informal key to sterile crusts from North America. Will send for confirmation… some day.

Definitely would need spot tests

But one option is Trapelia placodioides: It looks like an areolate sterile crust with soralia at least initially associated with cracks.

The lichen in question here is white-off crust.

It intermixes with Pleopsidium and grey-colored crust, which is addressed in observation 189340. Interesting features of this specimen is its white lobes on the perimeter, and slightly darker thallus immediately inwards from those lobes. The lichen dwells in crevices and other protected locations around sandstone butte (bottom photo).
