Description

The rock gnome lichen is endemic to high elevations in the southern Appalachians and is the only North American member of the genus Gymnoderma. Gymnoderma lineare is found growing on rock faces in dense colonies usually less than one meter square in size. The species is recognized by the straps, or squamules, that protrude perpendicular to the rock face. The squamules are thin, blue-grey on top, white below and fade to black at the base. Black fruiting bodies may be found from July to September. However, the genetic identity of each colony is unknown and each may represent a single clone (Weakley, 1988). According to Hale (1979), G. lineare is one of the most unusual, endemic lichens in North America.
