Usnea lichen grows abundantly on trees in Europe and North America as a species of Parmeliaceae, a large and diverse family of Lecanoromycetes .
Lichens are not plants, rather they are organisms composed of fungi and algae. Usnea lichen grows and thrives symbiotically with trees. It loves to thrive on sick or old and moribund trees, causing some people to blame usnea lichen for the death of their trees. City trees rarely have usnea lichen because it is very sensitive to air pollution.
Usnea lichen is also known as Songluo (in Chinese), Old man’s beard, Hanging hair, or just tree moss.
