Gyrocollema rupestrinum (Zahlbr.) Henssen

Distribution: C - Abr (Schultz 2014).

Description: Thallus endolithic, continuous, homoiomerous, poorly evident, appearing as a subfarinose, grey patch. Apothecia circular in outline, at first immersed, then subsessile, c. 0.5 mm across, with a deeply urceolate, at first brown but finally black disc, and a distinct thalline margin (sometimes appearing perithecioid when dry). Thalline exciple ecorticate, reddish brown in upper and outer parts; proper exciple poorly developed; epithecium brownish, K-; hymenium colourless, 90-100 µm high; paraphyses coherent, thread-like, mostly simple. Asci (6-)8-spored, sublinear-elongate, 70-79 x 23 µm. Ascospores 1-celled, hyaline (some of them turning pale brown at maturity), globose to ovoid, 9.5-14 x 7.7-13 µm, thin-walled. Photobiont cyanobacterial (Scytonema). Spot tests: all negative. Chemistry: without lichen substances.

Note: this very poorly understood species is known only from the type material, collected by Ginzberger in the Gran Sasso Massif (Central Apennines) on calcareous rocks above 2400 m.
