Locality: 29°16’0.54"N, 103°14’57.21"W, el. 1465-1870 m
Substrate and habitat: on rocks and boulders in the pine-oak woodland at the bottom of a deep canyon on the east side of the Chisos Mountains.
Identification: Something about this lichen seems to suggest Pertusaria. There are only two species of Pertusaria on the checklist of park lichens: azulensis and tejocotensis. As it turns out, Sharnoff has a photo of Pertusaria tejocotensis from Big Bend National Park on his web site. Hmmm. Could it be a match?
Common name: wart lichen
