HABITAT oldgrowth chaparral and conglomerate outcrops at top of high transverse ridge; SUBSTRATE north face of conglomerate cliff; ASPECT shaded; NOTES endolithic, scattered large tough black flexuous apothecia, rims thick even to shallowly radially split very prominant shiny never reducing, disk matt black turning very faintly reddish-black when wet, epihymenium dark brown POL+, hymenium hyaline POL-, hypothecium colorless but opaque POL+, patches of algae below hypothecium, exciple with dark brown margin and red-brown center POL+ clearing in K, all else constant in K, apothecia originating as black bumps which are apparently all exciple; SPORES many per ascus, oblong, hyaline, simple, smooth, ~4-6 × 2-2.5 µm.
Thought this might be S. reebiae, but in the end decided that one of the close-ups shows a vegetatively-dividing apothecium, and it looks a lot like a specimen from Mount Gleason.
