 Life habit: lichenized; Thallus: little or none, crustose, continuous or areolate, margin thinning at edge, without elongated lobes; prothallus: absent; surface: orange or gray, smooth, without asexual propagules; cortex: cellular, 28-56 µm thick, granules absent; medulla without granules; Apothecia: adnate, 0.4-0.8 mm in diam., lecanorine; disc: orange, flat or concave, epruinose; margin: persistent, raised; thalline margin absent; proper margin visible, concolorous with disc; parathecium: consisting of radiating hyphae; exciple below hypothecium irregular hyphae; epihymenium: golden, K+ red, C-; hymenium: hyaline, 70-85(-90) µm tall; paraphyses: 2-3 tip cells slightly swollen, not branched; subhymenium hyaline; asci: cylindrical, 8-spored; ascospores: hyaline, 2 locules, ellipsoid, 11-18(-19.5) x 4-5.5(-8.5) µm, isthmus 1.5-3 µm, spore end wall thin; Pycnidia: present, totally immersed, ostiole orange; Spot tests: Thallus K- or K+ red; Secondary metabolites: parietin, fallacinal, emodin, teloschistin, and parietinic acid.; Substrate and ecology: on soil, non-calcareous rocks, or calcareous rocks; World distribution: coastal, western North America; Sonoran distribution: southern California, Baja California and Baja California Sur.; Notes: Caloplaca luteominia var. luteominia has a thallus that is quite variable from very little to fairly well developed. The proper margins of the apothecia are relatively thick and raised. The narrow spore isthmus separates this from other similar species. The discs in this variety are dull orange compared with the bright red of var. bolanderi.
