Lepraria goughensis is a little-known species of leprose lichen in the family Stereocaulaceae.

[3] Lepraria goughensis forms a leprose, powdery, greyish-green thallus.

The soredia are abundant and very fine, measuring 20–26 micrometres in diameter, with numerous projecting hyphae present.

The species contains lecanoric acid, with minor to trace amounts of gyrophoric acid and strepsilin, and trace amounts of fragilin, 7-chloroemodin, and flavo-obscurin C. Spot tests show K−, C+ (red), KC+ (red), and Pd−.

It occurs in shady, humid places and is known only from Gough Island in the South Atlantic Ocean.
