but you might check the Pertusaria key in Richard Harris’s More Florida Lichens, Including the 10¢ Tour of Pyrenolichens There are a whole pile of these things that all look the same but have subtly different chemistry. Beware some of the names are out of date. You might double-check against James Lendemer’s Preliminary Keys to the Typically Sterile Crustose Lichens in North America to catch taxonomic corrections.
