Parmotrema coralliforme (Hale) Hale, 1974
Diagnostic description:
Parmotrema coralliforme is distinguished by the arbuscular structures, which are usually ciliate and esorediate, the effigurate maculae and the pale brown and rhizinate marginal zone in the undersurface.
It can be compared with P. ramusculum, which develops eciliate and strongly sorediate arbuscular structures, has punctiform maculae, sparse cilia (abundant in P. coralliforme) and the black naked marginal undersurface. See under P. ramusculum comments about other species.
