Ocellularia rivasplatana is a species of corticolous (bark-dwelling) lichen in the family Graphidaceae.

The type specimen was collected by the first author from a low-elevation primary forest in the Bukit Timah Nature Reserve.

[2] The thallus of the lichen is light green, lacks a prothallus, and measures up to 10 cm (4 in) in diameter.

The photobiont partner of the lichen is from the green algal genus Trentepohlia; their cells are yellowish-green and measure 6–10 by 5–8 μm.

Although Ocellularia exigua is somewhat similar in morphology, O. rivasplatana has larger apothecia with broader pores and a black-rimmed margin, which is filled with black-topped columella.
