A pan-American species new to the Galapagos; found mostly inland, often on mountain peaks and outcrops (currently known from Santiago, Pinzón, and Santa Cruz Island). The sorediate R. camptospora possibly forms a species pair with the fertile R. puiggarii. Both species do not contain secondary metabolites in their medulla, have thallus lobes that originate from a central holdfast, and are sparingly, mostly dichotomously branched. The lobes of R. camptospora are, however, basally angular and soon become flattened, whereas lobes of R. puiggarii are very strongly canaliculate, rolled up and thus appear terete.
