  • 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.

  • Very common across most of the Northern hemisphere, oakmoss is a type of fruticose lichen found not only on oaks, but pines and firs as well. In France and other parts of Southern Europe, it is harvested commercially for making perfume that has a sharp, slightly sweet odor. This one was found along with many hundreds of others above Soos Creek, in Kent, Washington State.

  • This striking yellow fungus seen here in Eastern Washington near the Idaho border  is a type of lichenized fungus found growing on trees. The bright yellow color comes from pinastric and vulpinic acids - two substances only found in lichens that are believed to repel the insects and other wildlife that might eat it. According to Swedish peasant folklore, this lichen will kill foxes, but is completely safe for wolves and dogs.

  • The so-called wolf lichen is a native fruticose lichenized fungus found in the Rocky Mountains, the Pacific Northwest and western Europe that gets its name from its historical use as wolf and fox poison in European cultures centuries ago. When mixed with meat and ground glass, it is reported to be deadly to all canines. Native tribes in the Pacific Northwest are said to have used it to make a yellow dye for furs, animal skins, feathers, etc. It was also used by some tribes to make poison arrowheads, while others it was used as a weak tea to treat stomach and other internal disorders. This one was photographed in the Turnbull National Wildlife Refuge just outside of Cheney, Washington.
