Diploschistes euganeus (A. Massal.) J. Steiner
Verh. zool.-bot. Ges. Wien, 69: 96, 1919. Basionym: Limboria euganea A. Massal. - Ric. Auton. Lich. Crost.: 155, 1852.
Synonyms: Diploschistes clausus (Flot.) Zahlbr.; Urceolaria euganea (A. Massal.) Jatta; Urceolaria subsordida Nyl.
Description: Thallus crustose, episubstratic, continuous to usually rimose-areolate, grey to brownish grey, smooth, dull or slightly shiny, epruinose, consisting of irregularly angular, 0.3-1.5 mm wide and 0.15-0.9(-1.3) mm thick areoles. Medulla white, I-. Apothecia perithecioid, immersed to semi-immersed in the areoles, up to 1.8 mm across (in section), with a blackish but sometimes white-pruinose, at first urceolate then flat disc which is not always visible from above, being concealed by a thick, entire or usually radially sulcate proper margin; thalline margin thin, poorly visible. Proper exciple carbonized, 70-90 µm thick, pseudoparenchymatous; epithecium poorly differentiated, colourless to brownish; hymenium colourless, 100-140 µm high, non-amyloid; paraphyses simple, flexuose, 1-1.5 µm thick, not swollen at apex. Asci (6-)8-spored, subclavate, the wall evenly thickened, with an abrupt apical thickening and a thin internal apical beak, lacking an apical apparatus. Ascospores muriform, with 3-6 transverse and 1-4 longitudinal septa, at first hyaline, then turning brown, broadly ellipsoid to subglobose, (16-)20-30(-32) x (10-)12-18(-20) µm. Photobiont chlorococcoid. Spot tests: K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
