Notes: Location: 29°16’28.21"N, 103°17’12.18"W, el. 1745-2170 m
Substrate and habitat: Abundant on boulders and shear rock walls overlooking open woodlands of piñon, juniper, and oak.
Identification: This seems to be a “yellowish Acarospora,” which means that it might be Acarospora or Pleopsidium. In this case, Pleopsidium might be indicated because the lobed border is fairly well pronounced, and the photo resembles MO #17450 from SE Arizona which was identified as Pleopsidium chlorophanum by Tom Nash. Pleopsidium chlorophanum and flavum are recorded from the park. Acarospora contigua is not.
Lichens of this sort on imposing rock walls give much character to the landscape of the Chisos and Davis Mountains in W Texas … and to Chiricahua NM in SE Arizona.
Common name: gold cobblestone lichen
