Carbacanthographis latispora is a species of corticolous (bark-dwelling) lichen in the family Graphidaceae.

Found in Venezuela, it was formally described as a new species in 2022 by Shirley Cunha Feuerstein and Robert Lücking.

The type specimen was collected near the savannah of La Esmeralda (Alto Orinoco Municipality Amazonas); here, in the Amazon rainforest, the lichen was found growing on a dead branch.

Its ascospores typically measure 140–155 by 30–35 μm and have from 13 to 17 transverse septa.

The specific epithet refers to its unusually broad ascospores.
