Description: Thallus crustose, episubstratic, pale grey-brown, usually starting the life-cycle on the thalli of crustose lichens. Apothecia lecideine, sessile, black to brownish black, round and convex to irregular, 0.25-0.5 mm across, dispersed or clustered, the largest ones usually forming deeply fissured agglomerations, with a black, irregularly and incompletely carbonized, often gyrose disc and a black, fissured, rough margin. Proper exciple carbonized in outer part, yellowish to colourless within; epithecium conglutinated in a dark brownish or reddish brown gel; hymenium colourless to to yellowish-orange, 75-150 µm high, often divided by sterile columns of conglutinated hyphae, the hymenial gel hemiamyloid, K/I+ light blue fading to light red; paraphyses coherent, 1-1.5 µm thick at base, septate, hardly expanded at apex; hypothecium colourless. Asci 200-300-spored, clavate to subcylindrical, strongly thickened at apex, the apical dome K/I-, the outer coat K/I+blue. Ascospores 1-celled, hyaline, narrowly ellipsoid to subcylindrical, (2.5-)4-5.5(-6) x 1-1.5 μm. Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
