Comm. Soc. Critt. Ital., 2, 1: 26, 1864.
Synonyms: Polyblastia abstrahenda Arnold?
Description: Thallus crustose, episubstratic, areolate to verrucose, the areoles 0.4-0.55 mm wide, rust-brown, patchily ochraceous or rarely ash-grey. Perithecia black, 0.3-0.4 mm across, subglobose, often with a depressed ostiolar region, at maturity immersed only at the base, usually located in the centre of the areoles. Basal parts of perithecia and surroundings sometimes K+ deep red. Involucrellum well-developed, 43-53 μm thick, clearly distinct from exciple except in the ostiolar region, reaching halfway down the perithecium, adpressed or only slightly diverging in the lowermost part; exciple dark brown throughout, 18-23 μm thick, merged with the involucrellum in the ostiolar region, pseudoparenchymatous; hamathecium of periphyses and periphysoids, interascal filaments absent; periphysoids slender, branched, 31-39 μm long, c. 1.5 μm thick; hymenial gel I+ red, K/I+ blue. Asci 8-spored, clavate, K/I-, fissitunicate, the wall thickened above, with an ocular chamber, dehiscent by extrusion of an endotunica to form a delicate rostrum. Ascospores muriform, with 6-7 oblique transverse septa and 3-4 longitudinal septa, hyaline or rarely turning pale yellowish brown when overmature, broadly ellipsoid, 24-32 x 14-18 μm. Photobiont chlorococcoid. Spot tests: K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
