Biogeography: Continent: Africa, Asia-Temperate, Europe, Northern America, and Southern America.

Ecology: Biotroph; lichenized; substrate non-calciferous or calciferous.

Thallus: Indistinct or crustose, not subdivided parts, strongly rimose or areolate (primarily areolate) (sometimes irregularly); separate thallus parts thin or thick (up to 2.0 mm). Thallus Outline: Soon disappearing. Upper Surface: White (like chalk) or lemon (citrine) (to beige), matt.

Medulla: Iodine reaction in Lugol's solution negative.

Reproduction Strategy: With sexual (and possible asexual) stages. Ascocarps: Becoming adnate (rarely) or soon sessile, strongly constricted at the base, 1.5-3 mm in diam.. Margin: Lecideine/biatorine, distinct or indistinct, brighter than the surrounding thallus (sometimes with weakly whitish pruina). Disk: Plane or weakly convex, black, epruinose. Exciple: Carbonized; bright green or aeruginose. Parathecium (proper excipulum): White, inspersed with crystals (and/or oil droplets present). Amphithecium (thalline excipulum): Present; 20-40 µm wide; photobiont sparse (sometimes). Epithecium: Apical cells slightly swollen, bright green, brown (rarely, when damaged ?), or turquoise. Hymenium: White; inspersed with crystals (rarely) or oil inspersed. Hypothecium: Weakly brown (rarely) or white; not inspers (strongly filled with crystals).

Ascospores: c. 8 per ascus, broadly ellipsoid or ovoid, 10-17 µm long, 6-10 µm wide; septa absent; wall thick (not halonate), distinctly differentiated into primary and secondary wall (not halonate), not ornamented (not halonate).

Pycnidia: Globular. Conidiophores: Vobis-type III. Conidia: Filiform or strongly curved; 18-25 µm long.

Secondary Metabolites: Atranorin, hopane-6a,22-diol, lichexanthone, or norlichexanthone (rarely; Trichlorlichexanthone very rarely), of the following substance class(es): xanthones.

Spot Tests: Upper surface: K – (negative) or + deep yellow, C – or very rarely + orange, PD – or + yellow.
