Dirinaria picta

Apothecia are rare with several species of Dirinaria including both this species and D. applanata. Since the thalli of both species have mounds of similar appearing soredia, they can be confused. In D. picta the lobes are somewhat elongated and branching while the tips are more or less separated from one another. Also notice the lobe tips frequently turn upward creating tiny concavities (see lobe at bottom right).
