Usnea is a genus of mostly pale grayish-green fruticose lichens that grow like leafless mini-shrubs or tassels anchored on bark or twigs.

Summary

[edit]
Description
English: Usnea - Cibodas Botanical Garden, Java Indonesia. They appear in areas with low levels of air pollution. Usnea is very sensitive to air pollution, especially sulfur dioxide. Under poor growing conditions, such as areas high in pollution, they may grow no larger than a few millimeters, if they survive at all. Where the air is unpolluted, they can grow to 10–20 cm long. It can sometimes be used as a bioindicator because it tends to only grow in those regions where the air is clean, and of high quality.
