Notes:
It is on old poplar bark and very rare species here.
Soralia are grainy and above central lobes as Physcia caesia has according my guidebook of 2008, but lobes too white & wide.

Bottom side is not black as Ph erumpens has
I took a sample, but did not crush it much

Could this be P. erumpens?

Another point against P. caesia is that it has mottled white spots on the surface. And P. caesia very rarely grows on bark (in North America at least).
