Protoparmelia capitata Lendemer, a sorediate species, is described as new to science. It is characterized by having large hemispherical soralia. Protoparmelia isidiata Diederich, Aptroot & Sérus., an isidiate species, is reported for the first time from North America. Both taxa produce alectoronic acid, and are shown to be widespread in sub-tropical portions of south-eastern North America. The placement of these two taxa in Protoparmelia is supported by a phylogenetic study of mitochondrial SSU rDNA sequences.
