Looks to be
ssp. cervicornis but for the K+y cortex (atranorin?). Definitely not large enough squamules to be the otherwise obvious
C. macrophyllodes.

Teloschistes flavicans [] [voucher]

| | APO | | few, tiny, no fibrils on marg |
Apparent lack of soredia bothers me, but the fuzz is quite distinctive, supposedly. Nope, according to
Nash, it should be completely grey due to dense tomentum. Can't be
T. contortuplicatus, either, because this is low elevation. Leaving only one other possibility.

Aspicilia? []
I have no interest in studying another Aspicilia without even so much as the benefit of a key!
| | GEN | | crust lichen, on exp calc rock near sea |
| | THAL | | lobate, lobes to 1.0x0.5mm, flat, orange, min roughened |
C. impolita is only on non-calcareous rocks;
C. saxicola is inland.
| | GEN | | crust lichen, on exp calc rock near sea |
| | THAL | | lobate, lobes 0.5-1.5mm wide, v deeply cracked, convex to warty, pale tan to brown, dker at marg, d lt pruinose, cracks quite dark to almost black despite medulla being white, K-, C-, KC- |
| | MED | | white, K-, C-, KC+pink faint and brief |

| | SPORE | | 8 per ascus, grey, 10x6-7um, 2 cell, sl constrict at sept, evenly thickened, never swollen even when immature |
Arg!
Nash's genus key is missing
Dimlaena! Once I finally bothered to look at this genus (which I knew it was from the start) it was easy.
Rinodina sucks, by the way. (
Brodo would've gotten the ID trivially, by the way.)
Lecanora muralis muralis [] [voucher]
| | GEN | | crust lichen, on exp calc rock near sea |
| | THAL | | lobate rosette, lobes ~2x1mm & contorted to flat to sl convex, white at v marg, shiny, lt greenish grey, K-, C-, KC+y |
| | APO | | lecanorine, sess to constrict, contorted, marg flush w disk & gen a bit ragged, disk pale brownish greenish, epruinose, to 1mm, thick contin algal layer, thick cortex w small brown crystals, epi brownish, hymen short & clear, hypo clear |
| | SPORE | | 8 per ascus, clear, 1 cell, ellip |
Depending on density of medulla, it is either
L. muralis muralis or
L. opiniconensis, but the latter doesn't occur anywhere near here.
| | GEN | | crust lichen, on exp calc rock near sea |
| | THAL | | chalky white, no cortex |
| | APO | | lecideine, black, raised rims, to 0.7mm, superficial, epi greenish black, hymen greenish & I+b, hypo brown, exciple black well-defined layer outside brown, ascus tip thick & trunc & apparently uniformly I+b |
| | SPORE | | 8 per ascus, clear, ellip-fusif, 1 cell, 12-15x4-5um, usually two bubbles |
I can't get good resolution on a stained ascus tip. Using
Nash: Keys to
Carbonea (but no species match),
Adelolecia sonorae (extremely rare), and
Lecidea (again I can find no species that match). I can't find mention of the green-black epihymenium (indeed epihymenium at all) in
Carbonea. Otherwise all three genera are plausible. I lean toward
Lecidea because the tip is not stained darkly but gets darker near the very tip, and I cannot begin to discern any sort of nonamyloid central axis structure, which the other two genera should have, the one being Lecanora-likem, the other being Bacidia-like. Hell, they're all three in different families! (
Brodo apparently puts
Bacidiaceae inside
Lecanoraceae, though.)
Carbonea appears to be exclusively inland montane;
Adelolecia sonorae has some problems (disappearing apothecial rim, barely pigmented hypothecium to name two);
Lecidea genus description matches perfectly in every aspect. Tellingly, for example,
Lecidea mentions "pseudodiblastic" spores, which I take to mean they usually have two bubbles, and the emerald-greenish I+b hymenium.
| | THAL | | lt to dk grey, lobes splaying to 2mm wide at rounded + cren tips, marg lifted displaying coarse dk grey soredia under tips, d and conspic maculate, no pruina, pale whitish to tan bel w scattered pale simple rhiz, K+y |
Sorediate Physcia on rock w K- med and pale lower surface: (in sCA area)
P. dimidiata 3mm lobes, pruina, crenulate w min lobules, soredia marginal
P. dubia 1mm lobes, rare pruina or maculae, soredia lips at tips, lter marg
P. tribacia 1mm lobes, rare pruina, shiny, soredia bel marg and tips, dker marg
On both this and the one from earlier, I'm going by the weak or absent pruina, the darker margins, and the soredia under the margin and tips.
