==Taxonomy== The genus was circumscribed in 1809 by the Swedish lichenologist Erik Acharius. His of the genus was as follows (translated from Latin): "Apothecium wart-like, formed from the thallus, including several thalamia covered by a very delicate, transparent perithecium, marked above by impressed ostioles; nuclei somewhat globose, containing cellular vesicles. Thallus cartilaginous-membranous, uniform". Acharius included a single species in the genus, Porina pertusa (originally named by Carl Linnaeus in 1767 as Lichen pertusus); this species is now known as Pertusaria pertusa.
