Summary

Usnea hirta is a species of beard lichen in the family Parmeliaceae. It was one of 80 lichen species first formally described by Carl Linnaeus in his 1753 work Species Plantarum. Friedrich Heinrich Wiggers transferred it to the genus Usnea in 1780. The lichen is sensitive to air pollution, and is often used as a biomonitor of sulphur dioxide. Usnea hirta has an extensive worldwide distribution, and it is morphologically variable, which has led to numerous intraspecific taxa (i.e. subspecies, varieties, and forms) being proposed in its taxonomic history....read more on Wikipedia.
