Lichenologist 24, 3: 223 (1992).
Basionym: Omphalaria polyglossa Nyl., Flora, Regensburg 59: 558 (1876).
Type locality: Cuba, Lich. Cubenses Ser. II, 47, Wright (H-NYL 42671 - lectotype; G, UPS - isolectotypes). Lectotypification by Henssen (1986: 494).
Type locality coordinates: Data lacking.
Molecular barcode: Data lacking.
Thallus: lobes narrow, 0.5-1.5 µm, flat, furrowed on the lower surface, bearing large granules (isidia in Henssen 1986) on the upper surface; hyphae arranged in a loos strand in the central part of the thallus and perpendicularly towards the margins; and excipulum proprium restricted to the basal part of the apothecia. In the type collection (H-NYL 42671) small flat lobes lying on the upper surface of larger lobes, are present. This character is not found in other collections from Mexico (Moreno & Egea 1992: 225).
Photobiont: Data lacking.
Chemistry: No lichen substances.
Ecology: On seapage slopes of more or less exposed limestone (Moreno & Egea 1992: 225).
