Polychidium muscicola [] 

Physcia phaea [] [voucher] 

GEN

on rock

THAL

cortex and medulla K+y, maculae, little pruina, black apo, abundant black rhiz

Phaeophyscia decolor [] 

GEN

on rock

THAL

cortex and medulla K-, no maculae, dusky med to dk gray, black apo, abundant black brushy white-tipped rhiz even under apo

Rhizocarpon eupatraeum [] [voucher] 

GEN

crust lichen, on basalt? pebbles in conglomerate just above creek

THAL

strongly areolate areoles   1mm, strongly convex, gray, matte, distinctly separate but packed polygonally into continuous thallus broad thin black prothallus

MED

white, thick, dense, K-? or K+y weak, KC+r weak

ALG

green

APO

black disks in place of areoles, flat, rim prom black shiny epi   thick, dk brown, made of v densely packed paraphyses tips, K+r hymen clear but with brown intrusions from epi hypo   dk brown, tight round packed cells exciple   black outer layer of cells, brown short radiating hyphae inside that clear in K ascus IKI+, para impossible to separate at all must be anastomosed

SPORE

8 per ascus, oblong-ellip, lt gray when immature to dk brown at maturity, muriform, 8+ cells seen from side, (29)33+/-4.0(39)x(14)15+/-1.2(17)um (Q=(1.9)2.1+/-0.13(2.3)) (N=8)

Not in Lichens but it did help confirm genus (could be Buellia potentially, but not with those paraphyses).  Nash et al. has a good match that occurs from arctic-alpine through to temperate: R. eupatraeum.  The spot tests were right, but it is supposed to have 4 spore per ascus (I saw several distinctly with 8), so there could well be another species exclusively north of the Sonoran range that matches even better.
