Prior to this, filamentous lichens of similar appearance had been classified within the broad genus Lichen, following the system used by Carl Linnaeus in his Species Plantarum (1753). Linnaeus recognised only three species that are now placed in Alectoria treating them as part of a much larger and undifferentiated group of lichens. [3]
