C. microsperma C. porinoides Clypeopyrenis is a genus of lichen-forming fungi in the family Pyrenulaceae.

[1] The genus was circumscribed in 1991 by Dutch lichenologist André Aptroot, with Clypeopyrenis microsperma assigned as the type species.

[2] This lichen, originally described from material collected in Costa Rica, is also found in the Caribbean and South America.

Clypeopyrenis porinoides was added to the genus in 2011; it was discovered in Costa Rica, close to the type locality of the type species.
