Pseudosagedia

Pseudosagedia is a genus of corticolous (bark-dwelling) lichens in the family Trichotheliaceae. It was first circumscribed as a section of genus Arthopyrenia by Swiss botanist Johannes Müller Argoviensis in 1862. Maurice Choisy elevated it to distinct generic status in 1949. Pseudosagedia was little used until, in 1995, Josef Hafellner and Klaus Kalb resurrected the genus to contain members of the Porina nitidula species group with the perithecial pigment called Pseudosagedia-violet and lacking setae.
