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

Ecology: Biotroph; lichenized; rarely lignicolous or corticolous (very rarely); substrate non-calciferous.

Thallus: Crustose, areolate (primarily areolate), bullate; separate thallus parts thin or very thick (0.2 - 1.2 mm). Thallus Outline: Soon disappearing. Upper Surface: Verruculose, white (like chalk), pale grey, or lemon (citrine), matt or weakly glossy (shiny).

Medulla: Iodine reaction in Lugol's solution negative.

Reproduction Strategy: With sexual (and possible asexual) stages. Ascocarps: Becoming adnate (sometimes) or soon sessile, strongly constricted at the base, 1-2 mm in diam.. Margin: Lecideine/biatorine, excluded, distinct or indistinct (about 0.1 mm). Disk: Plane, weakly convex, or strongly convex (when old), black, epruinose. Exciple: Carbonized; dark blue or dark green. Parathecium (proper excipulum): Brownish yellow (rarely) or brownish red. Amphithecium (thalline excipulum): Present. Epithecium: Apical cells not swollen, slightly swollen, or distinctly swollen (sometimes), green, turquoise, or olive (rarely, when damaged ?). Hymenium: White. Hypothecium: Brown, brownish yellow, or brownish red (hyphal ropes, stretching into the excipulum).

Ascospores: c. 8 per ascus, broadly ellipsoid or ovoid, 8-16 µm long, 5-9 µm wide; septa absent; wall thick (not halonate), distinctly differentiated into primary and secondary wall (not halonate), not ornamented (not halonate).

Pycnidia: Globular (wall brown, at upper side blackish brown). Conidiophores: Vobis-type III. Conidia: Filiform or strongly curved; 15-30 µm long.

Secondary Metabolites: 4,5-dichloro-3-O-methylnorlichexanthone and rarely arthothelin (2,4,5-trichloronorlichexanthone), atranorin, chloroatranorin, diploicin, and thuringione (= 2,4,5-trichloro-3-O-methylnorlichexanthone).

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