Abstract

A new species of Graphis is described from Cameroon, Africa. The new taxon is distinguished by a greyish-green, glossy, uneven, and continuous thallus. Further, it possesses stellately branched lirellae, and its entire labia are covered almost completely with thick thalline margin. It also has a completely carbonized proper exciple, which is considerably thick at the base, one-spored asci, and muriform hyaline to yellowish ascospores.
