Be sure there aren’t two things here

Fertile thallus looks slightly different texture and color than sorediate thallus. I could convince myself there are two species growing intermixed. You could check some random microscopic things like cortex thickness, shape and size of cells in cortex, presence o epinecral layer, whether the orange pigment in C+r or not, etc. If they are the same across the board, then probably the same species, just that the fertile areoles look slightly different. If there are many differences, it would confirm that they really are different.

If you are really keen. Or just name the sorediate one and avoid the whole issue!
