  Xanthoparmelia waboomsbergensis is a species of foliose lichen in the family Parmeliaceae. It was formally described as a new species in 2002 by Australian lichenologist John Elix. The type specimen was collected from the summit of Waboomsberg mountain (Cape Province) at an altitude of 1,220 m (4,000 ft). The species epithet refers to the type locality, the only place the lichen is known to occur.
  
  ## Description
  
  The thallus of Xanthoparmelia waboomsbergensis has a somewhat crustose morphology, with a tight attachment to its substrate; its colour is pale yellow-green, reaching a diameter of up to 1.5 cm (0.6 in). The lower thallus surface is black, with simple (i.e., unbranched), black rhizines. Xanthoparmelia waboomsbergensis contains several lichen products: stictic acid and constictic acid as major metabolites, minor amounts of usnic acid, and trace amounts of norstictic acid and cryptostictic acid.
