Pseudocyphellaria allanii is a species of corticolous (bark-dwelling) and foliose (leafy) lichen in the family Peltigeraceae.

Found in New Zealand, it was formally described as a new species in 1982 by Bernd Renner and David Galloway.

The type specimen was collected by Galloway on the path to Emily Falls on Mount Peel (South Canterbury); here it was found growing on a fallen Pseudowintera on a stream bank.

[2] The specific epithet allanii honours New Zealand botanist Harry Allan, who "described the vegetation of Mt Peel, and who later promoted interest in New Zealand lichens".
