Caloplaca nubigena (Kremp.) Dalla Torre & Sarnth.

Die Flechten von Tirol: 184, 1902. Basionym: Callopisma ochraceum var. nubigenum Kremp. - Denkschr. bot. Ges. Regensurg, 4, 2: 163, 1861.

Synonyms: Blastenia nubigena (Kremp.) Müll. Arg.; Caloplaca nubigena (Kremp.) Dalla Torre & Sarnth. var. nubigena

Description: Thallus crustose, endosubstratic or very thinly episubstratic, ochraceous orange to orange, continuous in endolithic forms to granular-rimose in epilithic forms, forming well-delimited, more or less orbicular patches, sometimes delimited by a thin pale prothallus, developing on the thalli of Clauzadea immersa. Apothecia pseudolecanorine, 0.2-0.5(-1) mm across, at least at the beginning immersed in pits of the rocks or (in epilithic forms) immersed in the thallus, later subsessile, with a dark orange, usually flat disc, and a slightly paler, often finally excluded proper margin, without a thalline margin. Proper exciple paraplectenchymatous, c. 140 µm wide, with a few algae at the base; epithecium orange-brown, K+ purple-red; hymenium colourless, 70-100 µm high; paraphyses mostly simple, with swollen, up to 7 µm wide apical cells; hypothecium colourless, rather indistinct, prosoplectenchymatous. Asci 8-spored, clavate, functionally unitunicate, apically thickened with a broad internal beak, the inner part of apex and external cap I+ blue, Teloschistes-type. Ascospores 2-celled, polarilocular, hyaline, ellipsoid, 9-13(-15) x (3-)5-7 µm, the equatorial thickening (“septum”) 2.5-4(-5) µm. Photobiont chlorococcoid. Spot tests: thallus and apothecia K+ purple-red, C-, KC-, P-. Chemistry: thallus and apothecia with unidentified anthraquinones.

Note: on calcareous rocks in upland areas, often near summits. Similar to C. coccinea, but differing in morphology, thallus colour, altitudinal distribution (not restricted to above treeline) and in its parasitism on Clauzadea immersa. See also note on C. keissleri.
