Biogeography: Colline and montane. Continent: Europe (Br, Cz, Ge, Gr, It, Lu, Po, Su), Southern America (Bolivia, Venezuela), Africa (North Africa, Angola, Republik of South Africa), and Australasia (W.A., N.T., S.A., N.S.W., Tasmania, N.Z. (Canterbury, Otago)).

Ecology: Biotroph; lichenized; endosubstratic or episubstratic (europ. specimens constantly endolithic, only with traces of an epilithic thallus); substrate non-calciferous.

Thallus: Not subdivided parts, areolate (primarily areolate) (not seen in europ. specimens); lobes angular at the front; separate thallus parts 0-.2-(.3) mm thick. Thallus Size and Differentiation: Large; main branches basally not constricted. Thallus Outline: Margin concolorous the thallus centre. Upper Surface: White or grey (very pale), plane; not sorediate; without thalloconidia thalloconidia.

Upper Cortex: Epicortex present (not seen in europ. specim.). Medulla: Iodine reaction in Lugol's solution negative.

Ascocarps: Soon sessile, strongly constricted at the base, 15-160 per cm², .5-.9-(1.5) mm in diam.. Margin: Not flexuose, persistent or excluded, 50-80 µm wide, epruinose. Disk: Plane to strongly convex, black, epruinose, pruina scarce, without an umbo. Exciple: Hyphae radiating outwards; 3-5 µm wide; grey or pink (rosé); inspersed with crystals. Epithecium: Apical cells olive, green, or black, cell pigment reacting with 10% HCl (in H2O). Hymenium: 35-52 µm high; white, pale green, or pink (rosé); iodine reaction: Lugol’s positive (bluish brown). Subhymenium: 17-35 µm high; white. Hypothecium: Brown or dark brown.

Ascospores: Cylindrical or oblong-obtuse, (6)-7.8-12.2-(14) µm long, (2)-2.7-4-(4.5) µm wide; wall not ornamented.

Secondary Metabolites: Not detected or rarely present, rarely confluentic acid and rarely planaic acid.

Spot Tests: Medulla: K –, C –, PD – ascocarp margin (in section): K – and + bluish red, C – disk: C – hypothecium: K – epihymenium: K –.
