Similar Species

Punctelia jackeri is similar and also has spots, but this species typically has soredia on the edges of the inner thallus lobes, and also tends to have brown tinged edges on the marginal lobes.

Parmelia sulcata can look similar as it may also have white spots, but there is usually evidence of white lines tracing across the lobes. Punctelia never has these white lines.
