Gibbosporina acuminata is a species of foliose lichen in the family Pannariaceae.

It was described as a new species in 2016 by Norwegian lichenologist Arve Elvebakk.

The specific epithet, derived from the Latin acumen ("sharp point"), refers to the spiked bumps (gibbae) on the spore covering (perispore).

[1] It occurs in the tropical forests of Queensland, Australia, and the Philippines.
