Thallus: Crustose or foliose, not subdivided parts, squamulose, lobed. Thallus Outline: Soon disappearing. Upper Surface: Greenish black or brown; special structures absent or present:; not pseudocyphellate; eciliate; without hairs; not isidate or isidiate; not sorediate (but soredioid masses from fragmenting isidia); not cephalodiate; not lobulate; without granules granules, without thalloconidia thalloconidia. Lower Surface: Attached by holdfasts; special structures absent or present:; not pseudocyphellate; not cyphellate; not rhizinate or rhizinate; without thalloconidia thalloconidia; not cavernulate; not tomentose.

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: Prominent; external filaments absent. Exciple: Grey or white. Periphyses: Absent. Epithecium: Apical cells brown or brownish yellow. Interascal Hyphae: Present, scarcely branched, not or scarcely anastomosed. Hypothecium: White.

Asci: Tholus thickened, amyloid, with non-amyloid wide axial body and divergent amyloid flanks towards apex; dehiscence lecanoralean.

Ascospores: c. 8 per ascus, almost globose, broadly ellipsoid, or ellipsoid, 6-13 µm long, 3-7 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.

Conidia: Fusiform, bifusiform, or bacilliform.

Secondary Metabolites: Present (unidentified brown pigments), of the following substance class(es): orcinol depsides, orcinol depsidones, ß-orcinol depsides, ß-orcinol depsidones, (higher) aliphatic acids, or amino acid derivatives.
