[2] The lichen thallus is a white, irregularly structured, areolate surface with a layer that includes a photosynthetic partner, both containing large calcium oxalate crystals.

Its fruiting bodies are either embedded or protruding, round, with very narrow openings, and contain large, oblong, colorless spores that turn violet-blue when stained with iodine.

The lichen was formally described as new to science in 2011 by the lichenologists Eimy Rivas Plata, Melizar Duya, and Robert Lücking.

[3] Ocellularia vizcayensis has a white thallus that is areolate, meaning it has a loosely structured surface divided into irregular areas.

[3] Ocellularia vizcayensis is known from a single, fully developed specimen found in an undisturbed lower montane rainforest of northern Luzon.
