Notes: on granodiorite used as barrier;
without permit only allowed collect a few apothecia (mushrooms)
photos compromised as forgot tripod that day; very attractive to me, so wanted to identify, but depending on how important should only spend so much time on a lichen
epilithic thallus in some places but mostly without;
in field thinking Lecidea, e.g. L. laboriosa;
section apothecium thinking Porpidia;
paraphyses extremely coherent in H2O and KOH, which made difficult to see detail and particularly get good iodine rx tholus;
is there a method to loosen up coherent paraphyses in section or squash?

That ascus stain could well be lecidea-type. I find that L. laboriosa is always difficult to get the paraphyses to separate even in K. Best plan is to do super-thin section, but then risk damaging asci, so it’s a trade-off. This microscopy looks perfectly in line with photos I have. I’m not surprised you weren’t able to find spores, that’s also not uncommon, esp. if you only have a few apothecia.
My opinion: safest name is L. laboriosa. There’s no way to increase confidence in any of the alternatives.
