Schadonia saulskellyana is described as new to science based on material from the southern
Appalachian Mountains in the eastern United States. The species appears to be endemic to the region and
mostly restricted to the bark of conifers. It is particularly abundant and frequent in the imperiled highelevation
spruce-fir forests of the region. The new species is distinguished from its congeners by its
corticolous habit, minutely areolate thallus with areoles that erupt into soralia which dissolve the areoles
and give the appearance of a leprose crust, epruinose, dark brown-black apothecia with a brown
hypothecium, and monosporous asci with large, muriform ascospores. It is also compared with other
genera of Pilocarpaceae, particularly Calopadia. Lopadium disciforme, a superficially similar species is also
compared to the new species and photographs, as well as a distribution map for eastern North America,
are provided for that species.
Keywords: Biogeography, disjunction, endemism, foliicole, North Carolina, substrate specificity.
