Nature Detective: Old Man's Beard (Usnea)

The pale green lichen Usnea, also known as Old Man’s Beard, can easily be spied hanging around trees in the Adirondacks. 

Its green tuffs remind me of the Lorax and the Truffula trees and as Dr. Seuss says, "Truffula trees are what everyone needs."

 Did you know?
lichens are not really plants but a blending of two separate organisms: fungus and algae.
• Usnea was used a respiratory antibiotic since 1600 B.C  
• Important in ancient Greek and Chinese medicine
• Has anti-microbial properties so can be directly applied to an open wound to stave off infection. 
• Make a tea or tincture out of it to treat lung infections. 
• Has been used to combat tuberculosis in studies.
•A white, stretchy, thin cord can be found when you pull the Old Man's Beard gently apart.
