Graphis yunnanensis is described here as a new species. It is taxonomically well characterized by entire labia, slit-like disc, lateral thalline margin, completely carbonized proper exciple, inspersed hymenium, 8-spored asci, muriform 25-45 × 8~12μm ascospores, and the presence of norstictic and stictic acids. The separation of the new species from other somewhat similar Graphis species is discussed. In addition, the study includes Graphis tenoriensis and Phlyctis kamatakana reported for the first lime from China. [ABSTRACT FROM AUTHOR]

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∼95 × 10 ∼15 μm 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 sipmanhi, Pertusaria pertusa, and Sarcographina cyclospora.
