Biogeography: Checklist records: Sonoran Desert and United States and Canada (continental).

Ecology: Biotroph; lichenized; terricolous, lignicolous, or corticolous; substrate non-calciferous or calciferous.

Lichen Photobionts: Primary photobiont present; chlorococcal. Secondary photobiont absent.

Thallus: Foliose, crustose, or fruticose, not subdivided parts, subfruticose or rimose, lobed. Upper Surface: Green, olive, or yellow; special structures absent or present:; not pseudocyphellate or pseudocyphellate; eciliate; without hairs; not isidate or isidiate; not sorediate or sorediate; not cephalodiate; not lobulate; without granules granules, without thalloconidia thalloconidia. Lower Surface: Attached by the whole lower surface, attached by holdfasts, or not attached, thallus vagrant; special structures absent.

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, directly at the tip of the thallus parts, soon sessile to stipitate. Margin: Prominent; external filaments absent. Periphyses: Absent. Epithecium: Apical cells green, grey, hyaline, or pink (rosé). Interascal Hyphae: Present.

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

Ascospores: c. 8 per ascus, ellipsoid, curved, fusiform, or oblong-obtuse, (6)-8.5-14 µm long, 3-4.5 µm wide, obtuse or aciculate; septa present; transversally septate, 1-2-transversally septate; wall thin, not thickened at the septum, hyaline, in Lugol's Solution negative, wall not ornamented.

Conidiomata: Absent resp. not observed or present; pycnidial; sessile to stipitate, formed all accross the thallus surface or along the thallus periphery.

Conidiogeneous Cells: Apical or intercalar. Conidia: Globose, bacilliform, bifusiform, or fusiform.

Secondary Metabolites: Not detected or present, of the following substance class(es): orcinol depsides, ß-orcinol depsidones, (higher) aliphatic acids, (tri-)terpenoids, and dibenzofurans [and usnic acids].
