Ocellularia albobullata

Ocellularia albobullata is a species of corticolous (bark-dwelling) lichen in the family Graphidaceae. Found in Costa Rica, it was described as new to science in 2011 by lichenologists Robert Lücking, Harrie Sipman, and Martin Grube. The type specimen was collected by Grube in Corcovado National Park at sea level. The lichen is known to occur in several locations in the coastal rainforest of southern Costa Rica. The specific epithet albobullata refers to the colour and form of the thallus, which is both white (albo-) and (i.e., convex and swollen). Ocellularia albobullata contains several secondary chemicals, including psoromic acid, subpsoromic acid, and 2'-O-demethylpsoromic acid.
