  • The bristly beard lichen (Usnea hirta) is a common type of fruticose lichen found in cooler or mountainous habitats and is a very good indicator species for environmental pollution. Where there is little to no air and water pollution, the strands of this fungus will grow long with many branches, and with poor quality surrounding, these lichens will either die, or not exceed more than a few millimeters in length. These long, healthy fiberous branches are indications a healthy Pacific Northwest habitat in next to Soos Creek in Kent, Washington.

  • Old man's beard (also known as Methuselah's beard lichen) is a very common lichen found in the trees of the Pacific Northwest's conifer forests that can reach lengths of over 20 feet and spreads by fragmentation. It can also be found in Northeastern but never quite reaches the size and length of its West Coast counterparts. This small specimen was found growing above a small waterfall just outside of Yelm, Washington on a wet, late winter morning.
