Observation 20521: Usnea subscabrosa Nyl. ex Mot.
When: 2009-04-05
Herbarium specimen reported

Notes: Location: 35°12’38.36"N, 85°54’0.40"W, el. 587 m, Beckwith’s Point Trail.

Substrate: Growing on the bark of a tall tree near a small stream.

Habitat: Oak-dominated eastern deciduous woodland at the western rim of the Cumberland Plateau.

Identification: Specimens of this lichen were determined Gary Perlmutter at the UNC Herbarium to represent Usnea pensylvanica, a recent split from the red beard lichen, Usnea rubicunda (Lendemer, 2004). The photo in Brodo of Usnea rubicunda is of a striking orange lichen. Local material is pale green, but the lichens in these photos show occasional bits of reddish orange. In the Ozarks, this species is “uncommon on hardwoods and occasionally rock in mature woodlands” (Harris and Ladd, 2005, p.236).
