title: Graphis yunnanensis (Ostropales, Graphidaceae), a New Lichen Species from China.
abstract: 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 × 8~12 µm 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 karnatakana reported for the first time from China.
