Comm. Soc. Critt. Ital., 1, 3: 157, 1862.
Synonyms: Acarospora urceolata (Anzi) Jatta; Biatorella urceolata (Anzi) J. Steiner; Polysporina urceolata (Anzi) Brodo; Sarcogyne urceolata var. herpes Norman
Distribution: N - Ven (Nascimbene & al. 2021), TAA (Nascimbene & al. 2022), Lomb. C - Abr (Nimis & Tretiach 1999, Gheza & al. 2021).
Description: Thallus crustose, endosubstratic, not evident. Apothecia lecideine, black, round, dispersed, immersed in the rock, 0.2-0.3(-0.5) mm across, with a mostly concave, punctiform disc and a rugulose-furrowed proper margin. Excipulum carbonized in outer part, black within, continuous with the hypothecium; epithecium dark brown; hymenium colourless, 50-80 μm high; paraphyses simple or branched in upper part, coherent (becoming lax in K), (1.5-)2-2.5(-3) μm thick at mid-level, the apical cells unexpanded or to 3 μm wide, occasionally with pigmented caps; hypothecium continuous with vegetative hyphae. Asci 100-200-spored, strongly thickened at apex, the apical dome K/I-, the outer coat K/I+ blue. Ascospores 1-celled, hyaline, ellipsoid to broadly ellipsoid, 3-5 x (1.5)-2-3 μm. Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
Note: on calcareous rocks in upland areas; probably much more widespread in the Alps and certainly rarer in the Apennines; related to S. cyclocarpa.
