Seems to me the only real options are:

C. scabriuscula – tips should have granules or soredia, stem squamules tend to grow on one side or all be oriented the same way making an obvious upper and lower side
C. squamosa – squamules on stalks should be smaller and randomly distributed, cups are rare, no granules or soredia
C. crispata – cups should have gaping holes in the center, no granules, often with few or no squamules

Chemistry could help: C. scabriuscula should be K+brown P+red UV-, the other two should be K- P- UV+ or K+y P+y UV-.
