Chapsa granulifera is a species of corticolous (bark-dwelling), crustose lichen in the family Graphidaceae. Found in Brazil, it was formally described as a new species by Andreas Frisch and Klaus Kalb in 2009. The type specimen was collected by the second author between {{cvt|100|and|200|km}} upstream from Manaus (Amazonas state), in a rainforest along the Rio Negro. It has a pale bluish-grey, velvety thallus measuring 0.02–0.05 mm thick, and a thin brown prothallus. The thallus is covered with yellow, soredia-like {{lichengloss|granules}}. It contains constictic acid and stictic acid as major and minor lichen products, respectively.
