Hepp ex Ahles, Pertusar. et Conotr.: 12, 1860.
Synonyms: Pertusaria alpina var. abietina Erichsen; Pertusaria alpina var. occulta Erichsen; Pertusaria laevigata (Th. Fr.) Anzi non (Nyl.) Arnold; Pertusaria leioplaca var. laevigata Th. Fr.
Description: Thallus crustose, endosubstratic or thinly episubstratic, smooth or somewhat verrucose, continuous to cracked, yellowish white, pale grey or yellowish green. Apothecia perithecioid, completely immersed in (1-)1.8-2.5 mm wide, basally not constricted thalline warts, with (1-)3-6(-9) pale to dark, punctiform ostioles per wart. Epithecium colourless or pale brown, K-, C-; hymenium colourless; paraphyses branched and anastomosing, poorly coherent. Asci 8-spored, broadly cylindrical, the apex with a broad ocular chamber, the outer sheath K/I+ blue, otherwise K/I-, Pertusaria-type, with uniseriately arranged spores. Ascospores 1-celled, hyaline, ellipsoid, (26-)30-70(-76) x (14-)20-32(-43) μm, with a double, 2.5-5 μm thick, finely punctate wall. Photobiont chlorococcoid. Spot tests: thallus K+ yellow, C-, KC- or KC+ yellow, P- or P+ faintly yellow; medulla P+ orange-red only around the apothecia, otherwise P-. Chemistry: 4,5-dichlorolichexanthone and stictic acid (major), constictic and cryptostictic acid (minor or traces).
