Carbacanthographis latispora (original) (raw)

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. It is only known to occur at the type locality. It has a whitish-grey thallus that lacks both a cortex and a prothallus. 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. Stictic acid, , and constictic acid are lichen products that occur in this species.
