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

Ecology: Biotroph; lichenized; bryophytic (and plant remains); episubstratic.

Thallus: Crustose (coarsely granular-papillate, often strongly verrucose, coarsely cracked-areolate), rimose or areolate (primarily areolate); separate thallus parts thin or thick (rather). Thallus Outline: Soon disappearing. Upper Surface: Pale grey, lime green, 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: Apothecioid, forming independently from the host thallus or mycelium, soon sessile, slightly constricted at the base, .5-1.5 mm in diam.. Margin: Lecideine/biatorine, excluded, distinct or indistinct (about 0.075 mm). Disk: Plane or weakly convex (later), black, epruinose or rarely pruinose. Exciple: Not carbonized; black (at edge, reddish within) or dark green. Parathecium (proper excipulum): Brownish red. Amphithecium (thalline excipulum): Present. Episamma: Without episamma or rarely with episamma. Epithecium: Apical cells green, dark green, or turquoise. Hypothecium: Brownish yellow or rarely brownish red (above, darker below).

Ascospores: c. 8 per ascus, broadly ellipsoid, ellipsoid, or ovoid, (7)-9-(18) µm long, (5)-(9) µm wide; septa absent.

Secondary Metabolites: 2,5,7-trichloro-3-O-methylnorlichexanthone, 5,7-dichloro-3-O-methylnorlichexanthone, atranorin, isoarthothelin (= 2,5,7-trichloronorlichexanthone), or thiophanic acid (= 2,4,5,7-tetrachloronorlichexanthone).

Spot Tests: Upper surface: C + orange ('orange').
