Note added on 07 May 2009: The identification of the Dermatocarpon in this observation needs to be re-evaluated in light of recent studies by Amtofta, Lutzoni, and Miadlikowska (The Bryologist, 2008). Dermatocarpon miniatum in North America is now restricted to a more northern, boreal species, and the populations in eastern North America formerly assigned to D. miniatum are now assigned to other species. The nature of the substrate plays an important role in the distribution of Dermatocarpon. It will be interesting to see how this new understanding applies to the Southern Appalachian region.
