Belongs within: Lecanoromycetes.

The Baeomycetaceae are a family of lichens containing green algae, found growing on soil, rocks or similar substrates (Cannon & Kirk 2007).

Characters (from Cannon & Kirk 2007): Thallus varied, usually crustose or squamulose. Ascomata sessile or shortly stipitate, sometimes clustered, formed on specialised generally non-lichenised thalline branches, flat or convex, pink or brown, the wall of interwoven hyphae. Interascal tissue of simple or sparingly branched paraphyses, often swollen at the apices. Hymenial gel J+ or J-. Asci thin-walled, not thickened at the apex, with a J+ or J- apical pore. Ascospores hyaline, simple or transversely septate. Anamorph pycnidial.
