Some of our herbarium specimens are of incredibly rare species. This is one of only two known collections of this species, and both collections were made within a mile of each other, on an exposed mountain slope in Shenandoah National Park. New York Botanical Garden curator James Lendemer named this species in honor of Gladys Anderson, a remarkable lichenologist and literal trailblazer who helped set portions of the Appalachian Trail.
