The apothecia appear to have a white pruinose and if a Lecanora, apothecia seem smaller than my previous observation referenced (see Mushroom Observer on this page). The thallus turned yellow with orange undertones with NaOH application.Scraping the thallus lightly produced yellow and removing the apothecia left a pink/red surface.
