Platismatia regenerans is a species of corticolous (bark-dwelling), foliose lichen in the family Parmeliaceae.

Found in Borneo, it was formally described as a new species in 1968 by William and Chicita Culberson.

The type specimen was collected by Mason Hale from the Kinabalu National Park in Sabah, at an elevation of 2,000 m (6,600 ft).

The species epithet refers to the "regenerative lobulae" that occur on older parts of the thallus.
