Herzogia, 31, 1: 134, 2018.

Synonyms: Acarospora glaucocarpa var. cumulata Arnold; Sarcogyne privigna var. calcicola H. Magn.

Distribution: N - TAA (Knudsen & al. 2023). C- Marc (Ravera & al. 2020), Abr (Ravera & al. 2020), Mol (Ravera & al. 2020).

Description: Thallus crustose, entirely endosubstratic, not evident. Apothecia lecideine, 0.2-0.6(-1) mm across, round to irregular in outline, often clustered and deformed by mutual compression, with an orange-brown to reddish black, epruinose, flat disc, and a more or less crenulate, smooth, black, epruinose proper margin curling inward above the disc. Proper exciple up to 120 µm wide, of thin radiating hyphae, the outer rim carbonized, black, sharply delimited from the yellow-orange medullary part; epithecium reddish brown or orange-brown, 10-15 µm high; hymenium colourless, 50-85 µm high, the hymenial gel euamyloid, IKI+ persistenly dark blue; paraphyses coherent, simple to sparingly branched, regularly septate, 2-3 µm thick at mid-level, the apical cells 3-4 µm wide; subhymenium colourless to yellow-orange, 20-40 µm high, IKI+ blue; hypothecium 10-40 µm high, IKI–, the hyphae c. 1 µm wide. Asci (50-)100-200-spored, cylindrical-clavate, strongly thickened at apex, the apical dome K/I-, the outer coat K/I+ blue. Ascospores 1-celled, hyaline, narrowly ellipsoid, 4-5 x 1-2 µm. Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.

Note: previously treated as a calcicolous form of S. hypophaea, this recently-described species is probably more widespread in Italy.
