Parmotrema reitzii Hale, 1977  

Parmotrema reitzii is recognized by the submarginal soralia, usually raised and forming branched structures, the pale brown to brown underside, with dimorphic rhizines, and the medullar chemistry, with salazinic acid and norlobaridone.

A close species is P. subsumptum (see comments under this species), where the soralia grow in the underside of the crisped lobes, and additionally do not produces norlobaridone.

Kurokawa (1991) placed P. reitzii as synonym of Parmotrema conferendum Hale, while Fleig (1997) situated it as synonym of P. subsumptum. The type of P. conferendum was not studied here, but with base in the type of P. subsumptum and its synonyms, P. reitzii is distinct booth morphologically (especially the soralia ontogeny) and chemically, i.e., by the production of norlobaridone.
