Cladonia are tricky

With a hand lens you can answer one important question — what exactly do the stems look like? Are they powdery or granular (sorediate), cottony (no cortex but also not sorediate), or waxy/shiny, either continuously or in patches (corticate)?

No soredia or cortex [stems should have irregular cross-section]:
  stems roughened/decorticate all the way to the base . . . __C. cariosa__
  stems corticate at the base . . . __C. symphycarpa__ or __C. polycarpoides__
    (separate based on size of squamules at base and K reaction of medulla)
Sorediate:
  none look promising
Corticate:
  __C. gracilis ssp. elongata__ or _ssp. turbinata_

any other way to know?

I wonder if it is C. gracilis?

Just another thought. Awfully short stalks, though…
