Abstract

Graphis upretii is a new lichen species discovered in Vietnam. The species is characterized by a loosely corticate, rough, whitish grey to greyish green thallus, elongate and irregularly branched lirellae with an apically thin complete thalline margin (negrosina morph), laterally carbonized, entire proper exciple, clear hymenium, hyaline, 16~20 transversely locular ascospores, and about $50{\sim}95{\times}10{\sim}15{\mu}m$ in size. In addition, members of the taxon produce norstictic and stictic acids. Currently, the lichen flora of Vietnam include Arthonia radiata, Brigantiaea tricolor, Coenogonium implexum, Dirina paradoxa, Herpothallon sipmanii, Pertusaria pertusa, and Sarcographina cyclospora.
