Medulla: Iodine reaction in Lugol's solution negative; not different with or without KOH pre-treatment (euamyloid).

Reproduction Strategy: Only known as sterile, asexually reproducing form or with sexual (and possible asexual) stages. Ascocarps: Apothecioid, orbicular, forming all across the thallus surface, soon sessile. Margin: Indistinct to distinct; external filaments absent. Exciple: Green or brownish yellow. Periphyses: Absent. Epithecium: Apical cells green. Hymenium: Iodine reaction: Lugol’s positive, not hemiamyloid. Interascal Hyphae: Present, scarcely branched, not or scarcely anastomosed. Hypothecium: Brown.

Asci: Tholus thickened, amyloid, with amyloid tube; dehiscence lecanoralean; exoascus euamyloid, not hemiamyloid.

Ascospores: c. 8 per ascus, ellipsoid, broadly ellipsoid, globose, or ovoid, (6)-8-12-(15) µm long, (4)-5-7.5 µm wide, obtuse; septa absent; wall thin, not thickened at the septum, hyaline, in Lugol's Solution negative, wall not ornamented.

Conidiomata: Absent resp. not observed or present; pycnidial; immersed, formed all accross the thallus surface.

Secondary Metabolites: Present, of the following substance class(es): ß-orcinol depsides and (higher) aliphatic acids.
