Add to Cart

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.
