Note: a species resembling in habitus Hymenelia epulotica and perhaps belonging to that genus, with a thin, continuous, grey to ochraceous thallus and small, immersed, later somewhat elevated apothecia with blackish discs covered by a white pruina; on calcareous(?) rocks, other ecological requirements not documented, growing together with Opegrapha rupestris (fide Schaerer); reported from Switzerland without a precise locality, and only known from the type.
