Description
Usnea is a unique species of herb because it is created through a symbiotic relationship between lichens and algae. Symbiosis refers to the living together of two different organisms. In the case of lichens, both the alga and the fungus benefit from the relationship. Other names for usnea include lichen moss and old man's beard. Usnea can be found in forests in northern North America and are also found in Europe.
