Pertusaria lueckingii is a species of corticolous (bark-dwelling), crustose lichen in the family Pertusariaceae.

[1] Found on the Galápagos Islands, it was formally described as a new species in 2015 by Frank Bungartz, Alan W. Archer, and John Elix.

The type specimen was collected on Floreana Island, where it was found growing on the bark of a south-exposed trunk of Cedrella odorata.

The soralia, which are reproductive structures, are irregularly shaped, ranging from 0.3 to 1.5 mm in size, and are scattered throughout the thallus.

The soredia, which are clusters of algal cells surrounded by fungal hyphae, are coarse and granular or have a coral-like appearance.
