Caloplaca pinicola
Description 5
Life habit: lichenized; Thallus: crustose, areolate, without elongated lobes; prothallus: absent; surface: blue-gray, verruculose, sorediate; soredia: fine, in delimited, laminal, cupuliform soralia; cortex: cellular, 14-21 µm thick, granules absent; medulla without granules; Apothecia: adnate or stipitate, 0.2-1 mm in diam., lecanorine; disc: brownish orange or orange, flat or slightly concave, epruinose; margin: persistent, flush or slightly raised; thalline margin present, concolorous with thallus; proper margin not visible; parathecium: elongate to oval cells; exciple below hypothecium amorphous; epihymenium: golden, K+ red; hymenium: hyaline, 60-75 µm tall; paraphyses: 1-2 tip cells slightly swollen, with few branches; subhymenium hyaline; asci: cylindrical, 8-spored; ascospores: hyaline, 2 locules, ellipsoid, 11-14(-15.5) x 5.5-7 µm, isthmus 2-4 µm, spore end wall thin; Pycnidia: present, totally immersed, ostiole black; Spot tests: apothecial margin K+ violet, 10% N+ violet, cN+ violet, C+ violet; thallus K+ violet, 10%N+ violet, cN+ violet unidentified anthraquinones and thalloidima green.; Substrate and ecology: on bark; World distribution: North America; Sonoran distribution: Arizona and Baja California.; Notes: Caloplaca pinicola has a dark gray thallus and apothecial margins and is very similar to C. cerina that has a continuous thallus while C. pinicola has a thicker areolate thallus sometimes with blue gray soredia and the spore isthmus is narrower. The soredia are variable and sometimes rare or absent. The prominent dark gray thalline margin of the apothecia of C. pinicola separates it from C. ahtii that also has blue gray soredia. Caloplaca pinicola is probably more common but has not been separated from C. cerina.
