in Coppins & al., Lichenologist, 24: 366, 1992. Basionym: Verrucaria allobata Stizenb. - Ber. naturw. Ges. St. Gallen: 501, 1882 (1880-1881).
Synonyms: Amphoroblastia allobata (Stizenb.) Servít; Polyblastia allobata (Stizenb.) Zschacke
Description: Thallus crustose, episubstratic, grey-green to brown, slightly uneven and faintly roughened, composed of goniocysts surrounded by hyphae with a sparingly papillate wall. Perithecia 0.1-0.25 mm across (in section), more or less globose, sometimes slightly barrel-shaped, 2/3 immersed to almost entirely superficial, grey-brown when young, later usually black, but paler around the ostiole, the surface smooth, matt. Exciple 2-layered, pigmented in outer part, colourless and of compressed cells within; involucrellum absent; hamathecium of periphysoids which soon dissolve into a poorly differentiated hymenial gel (interascal filaments in mature ascomata lacking). Asci 8-spored, clavate, thin-walled, fissitunicate with a very thin exoascus, surrounded by a hemiamyloid gel. Ascospores muriform, hyaline, ellipsoid, (25-)29-35(-45) x 10-15(-17) μm. Photobiont chlorococcoid. Spot tests: K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
