Rozpr. Cesk. Akad. Ved. Rocn., 65, 3: 40, 1955.
Synonyms:
Distribution: N - Lig.
Description: Thallus squamulose, heteromerous, brown, grey-brown or green-brown, dark green when wet. Squamules 0.3-0.7 mm wide, concave to flat, adpressed, sometimes imbricate, crenulate-lobulate; lower surface whitish to pale brown, erhizinate. Upper cortex pseudoparenchymatous; lower cortex absent; medulla white, of loosely interwoven hyphae. Perithecia black, globose to broadly pyriform, without involucrellum, immersed in the squamules, 0.13-0.2 mm across. Hymenium colourless, I+ red, K/I+ blue; paraphyses absent, substituted by periphyses; hymenial algae rounded, 2-3 μm wide. Asci 2-spored, clavate to cylindrical-clavate, bi- and fissitunicate, thin-walled, the wall non-amyloid. Ascospores muriform, at first colourless, then pale brown, ellipsoid, often of different sizes in the same ascus, the largest ones 28-40(-50) x 12-20(-24) μm. Photobiont chlorococcoid (Stichococcus, present in both thallus and hymenium). Spot tests: thallus and medulla K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
Note: described from Dalmatia, this rare calcicolous species, which is similar to the silicicolous E. psorodeum, was also reported from Austria, France, Switzerland and Germany.
