Identification: These are short, cup-forming Cladonia with round, peltate scales lining the inside of the cups, so there are two species to consider (characterizations from McCune and Geiser, 2009, pp.70 and 95): Cladonia pocillum ("primary squamules closely packed or subcontinuous, rosette-forming ... drier sites") Cladonia pyxidata ("primary squamules separate, not closely packed or forming rosettes ... mesic sites")
