Specimen available

HABITAT mixed birch-conifer forest on ridge at top of steep southern slope of mountain; SUBSTRATE Abies bark; ASPECT partly sunny; NOTES ruffled like Parmotrema, thick rounded crenulate lobes, predominantly simple short black rhizines, conspicuously rugose-wrinkled in interior, abundant pustules breaking into schizidia all over interior, no soredia, maybe slightly maculate, epruinose, eciliate; MEDULLA white to off-white, K~ orangish/brownish faint, C~ orangish to pinkish fading orange where anything happens especially in algal layer, KC+ orange immediately turning pink fading yellow.

Chemistry suggests H. virginica, but it looks nothing like the other 2 or 3 specimens I’ve seen (one of which was determined by J. Lendemer). The other one with C+o test is H. laevigata, but it’s nothing like that one, either. I’m stumped.
