Ocellularia rivasplatiana
Ocellularia rivasplatiana is a species of corticolous (bark-dwelling) lichen in the family Graphidaceae. Found in Singapore, it was formally described as a new species in 2015 by Gothamie Weerakoon and Robert Lücking. The type specimen was collected by the first author from a low-elevation primary forest in the Bukit Timah Nature Reserve. It is only known to occur at the type locality. The species epithet honours lichenologist Eimy Rivas Plata.[1]

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. rivasplatiana has larger apothecia with broader pores and a black-rimmed margin, which is filled with black-topped columella.[1]
