Was this growing in a shady area in a forest? If you zoom all the way in, the surface looks like its covered with lumps of cortex, which would rule out Cladina (e.g. C. subtenuis). Both Cladonia furcata and C. uncialis form branchy cushions like this. The latter should generally have thicker stalks and “gaping” axils. The former would normally have at least some squamules. Their chemistry differs: C. furcata with fumarprotocetraric acid (PD+r KC-), C. uncialis with usnic acid (PD- KC+y).
