Example of an extended specimen generated by the Dimensions of Biodiversity award to study lichen biodiversity gradients in the Southern Appalachian Mountain Biodiversity Hotspot of the eastern United States. The specimen (E. Tripp 6292) was collected in Little River Canyon National Preserve, Alabama, and formally described as Lecanora markjohnstonii by the project team in a paper lead authored by a graduate student from University of Colorado, Boulder. The primary specimen extensions were created and disseminated by The New York Botanical Garden.
