Synonyms: Polyblastia spadicea (Wallr.) Jatta; Staurothele catalepta auct. p.p. non (Ach.) Blomb. & Forssell; Staurothele elegans (Wallr.) Zwackh; Stigmatomma spadiceum (Wallr.) Körb.
Distribution: N - TAA (Herb. Nascimbene 2105), VA (Matteucci & al. 2013), Lig (TSB 33552). C - Abr (Jatta 1909-1911). S - Bas (Nimis & Tretiach 1999).
Description: Thallus crustose, episubstratic, thick, grey to chestnut brown, rarely dark brown, sometimes pale grey-pruinose, areolate and often secondarily cracked into small groups of convex areoles, rarely delimited by a white to brownish prothallus; fertile areoles distinctly larger than the sterile ones. Perithecia black, 0.2-0.45 mm across (in section), mostly one per areole, either completely immersed, or slightly projecting and with the basal parts covered by a thalline layer. Involucrellum apical, poorly developed, dark brown to black, rarely reaching to base-level; exciple colourless or pale brown, darker around the ostiole; hymenial gel I+ red (I+ blue at very low concentrations of iodine), K/I+ blue; hymenial algae globose-cuboid, 2-5 μm wide; hamathecium of periphyses and periphysoids, interascal filaments absent. Asci 2-spored, verrucarioid, clavate, the wall thickened above, with an ocular chamber, after dehiscence with a delicate extruded endotunica, I-, K/I-. Ascospores muriform, pale brown at maturity, oblong-ellipsoid, 33-54 x 12-25 μm, the upper spore wider and often longer than the other. Photobiont chlorococcoid, present in both thallus and hymenium. Spot tests: K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
Note: on calcareous or basic siliceous rocks in open habitats, mostly below the subalpine belt. See also note on S. areolata.
