Notes: HABITAT oldgrowth chaparral and conglomerate outcrops at top of high transverse ridge; SUBSTRATE granitic cobble loose on ground; ASPECT sunny; NOTES thallus brown contiguous rimose, K+y to somewhat orange after a long time, no norstictic crystals, apothecia large 1-2 per areole very elevated in age with thin white ring on inside of thalline rim, disk black and epruinose, cortex POL-, medulla POL+ clearing in K, paraphyses with 4-5 swollen cells; SPORES 8 per ascus?, hyaline, ellipsoid, simple, smooth, 18-20 × 11-13 µm; CONIDIA no pycnidia found unfortunately.
Based on brown thallus and lack of norstictic acid, it must be either Aspicila anglica, A. knudsenii, or A. pacifica. A. knudsenii has nonmoniliform to submoniliform paraphyses; A. anglica spore size is closer than A. pacifica; but A. pacifica often has a white rim around the apothecia, while A. anglica does not and is verrucose. A. santamonicae might match even better except for the lack of norstictic crystals. Conidia length would sure help.
