Ecology: Biotroph; lichenized; endosubstratic; substrate non-calciferous. Thallus: Separate thallus parts 0 mm thick. Thallus Size and Differentiation: Large. Medulla: Iodine reaction in Lugol's solution positive (somtimes very pale or rather local). Ascocarps: Soon sessile, slightly constricted or strongly constricted at the base, 25-50 per cm², .5-1-(2.7) mm in diam.. Margin: Not flexuose or slightly flexuose, persistent or excluded, 50-150 µm wide, rarely epruinose. Disk: Plane, weakly convex, or strongly convex, black, epruinose, without an umbo. Exciple: Grey; not inspersed with crystals or inspersed with crystals. Epithecium: Apical cells olive, green, or turquoise, cell pigment reacting with 10% HCl (in H2O), cell pigment HCl+ blue. Hymenium: 35-55 µm high; white; iodine reaction: Lugol’s positive. Subhymenium: 0-70 µm high; white or pale green. Hypothecium: White or pale green. Ascospores: Ellipsoid or oblong, (5)-6.6-10.6-(13.5) µm long, (2.5)-3.1-4-(5) µm wide; wall not ornamented. Secondary Metabolites: Not detected. Spot Tests: Medulla: K –, C –, PD – ascocarp margin (in section): K – or + bluish red (cortex), C – disk: C – hypothecium: K – epihymenium: K –.
