Taxonomy
It was first formally described by Carl Linnaeus in his 1753 work Species Plantarum. William and Chicita Culberson transferred it to the genus Platismatia in 1968.
Research
Platismatia glauca can acclimate to large variations in the availability of environmental nitrogen. It efficiently assimilates increased nitrogen into its thallus, increasing the size as well as the photosynthetic capabilities of its photobiont.
Chemistry
Several secondary metabolites have been isolated from the lichen, including the nor-triterpene ketone, 30-nor-21α-hopan-22-one, the depsides atranorin and chloroatranorin, and the aromatic compounds methyl β-orcinolcarboxylate and chloroatranol.
