Zeitschr. f. Naturw., 80: 251, 1908. Basionym: Paraphysorma ambrosianum A. Massal. - Mem. Lichenogr.: 136, 1853.
Synonyms: Dermatocarpon ambrosianum (A. Massal.) A. Massal.; Dermatocarpon ambrosianum var. effusum A. Massal.; Dermatocarpon ambrosianum var. orbiculare A. Massal.; Staurothele catalepta auct. p.p. non (Ach.) Blomb. & Forssell
Description: Thallus crustose, episubstratic, areolate, dark grey-brown to dark brown, sometimes delimited by a darker hypothalline line, the areoles 0.2-1 mm wide, flat to strongly convex, the fertile ones similar to the sterile ones or only slightly larger. Perithecia black, 0.2-0.3 mm across, immersed in the areoles, with a black involucrellum. Hymenial algae 2-5 μm wide; hymenial gel I+ red (I+ blue at very low concentrations of iodine), K/I+ blue; hamathecium of periphyses and periphysoids, interascal filaments absent. Asci (1-)2-spored, clavate, the wall thickened above, with an ocular chamber, after dehiscence with a delicate extruded endotunica, I -, K/I-. Ascospores muriform, at first hyaline then turning brown, ellipsoid to narrowly ellipsoid, (25-)30-50(-55) x (12-)16-25 μm. Pycnidia black, immersed in the thallus. Conidia bacilliform. Photobiont chlorococcoid, present in both thallus and hymenium. Spot tests: K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
