Notes:
Location: 35°12’48.33"N , 85°54’14.26"W, el. 524 m. Piney Point.

Substrate: Growing on a few slender twigs of bushes overhanging the bare sandstone rim of the western escarpment of the Cumberland Plateau. The lichens were 2-3 m above the ground, positioned to benefit from fog and clouds scraping past the rim of the canyon.

Habitat: Pine dominates the rim of the canyon, and oak and other deciduous hardwoods cover the plateau behind it and the canyon below.

Identification: Specimens of this lichen from the nearby Sewanee-St.Andrew’s Trail were determined by Gary Perlmutter at the UNC Herbarium to represent Tuckermannopsis ciliaris (medulla C+ pink).
