Collection location: Sewanee, Franklin Co., Tennessee, USA [Click for map]
Location: 35°12’45.15"N 85°53’47.26"W el. 586 m, Sewanee-St.Andrew’s Trail.
Substrate and habitat: Growing on a clump of sandy soil adhering to the base of an emergent sandstone rock near the rim of a canyon, in oak-hickory woodland on the western rim of the Cumberland Plateau.
thallus: C-, K+ pale yellow, KC-, Pd+ pale yellow.
Both the K+ pale yellow and Pd+ pale yellow spot tests take 1-2 min to develop, and the resulting pale yellow color is hardly evident against the color of the lichen’s outer cortex, but it becomes clearly visible on a piece of absorbent white paper brought into contact with the damp thallus.
Identification: Pale gray, hollow, finger-like, branching podetia emerging from a persistent, granular thallus.
United States, Tennessee, Franklin County, Sewanee, Sewanee-St.Andrew’s Trail. 20 Feb 2010. Chris Parrish 0061.
