Description: Thallus crustose, thinly episubstratic, yellowish grey to grey-green, continuous or more or less granular-warted, forming up to 1(-2) cm wide, rounded to ellipsoid patches, sorediate, without a distinct prothallus. Soralia yellowish green, partly discrete and punctiform, up to 0.2 mm in diam., partly confluent and convex; soredia farinose, up to 20(-25) μm in diam. Apothecia very rare, biatorine, 0.15-0.3 mm across, pale brown to black, greenish in shade forms, sessile, with a flat to convex disc. Epithecium more or less blue-green (K-, N+ purple), olive-brown (K-, N-), or a mixture of both; hymenium colourless, 40-55 μm high; paraphyses 1.5-2 μm thick at mid-level, much branched and anastomosing, the apical cells more or less clavate, the apical cells up to 3 μm wide; hypothecium colourless. Asci 8-spored, broadly clavate, surrounded by a gelatinous, amyloid sheet, with a well-developed, amyloid tholus containing a widely cylindrical axial body and a poorly developed, bluntly conical ocular chamber, more or less Lecanora-type, with spirally arranged spores. Ascospores 3-7-septate, strongly curved and mostly S-shaped, 20-40 x 2-3.4 μm. Photobiont chlorococcoid. Spot tests: soralia K-, C+ fleeting and faintly pink, KC+ fleeting and faintly pink (reactions visible only in squash preparations!), P-, UV-. Chemistry: gyrophoric acid (traces).
Note: a mainly mild-temperate early coloniser of smooth bark, rarely occurring also on siliceous rocks and on leaves of Buxus and Abies. Probably overlooked, being mostly sterile, it was included in the Italian red list of epiphytic lichens under the “Least Concern” category (Nascimbene & al. 2013c).
Growth form: Crustose
Substrata: bark and rocks
