| Abstract: | Based on the specimens collected from Yunnan Province, the lichen genus Schizotrema Mangold & Lumbsch is reported as new to China, with the species Schizotrema guadeloupense(Hale)Mangold & Lumbsch. Among Graphidaceae, the genus is characterized by its ascomata with concentrically layered margins composed of carbonized excipular remnants of older hymenia; the proper exciple is fused to indistinctly free, periphysoids are usually present, and the ascospores are transversely septate to muriform. The species S. guadeloupense is also new to Asia. In addition, notes of other five species in the genus are also given, with ecology and distribution, and world-wide key to species of Schizotrema is described in the present paper. All these results provide basic data information for the taxonomy of the family Graphidaceae. |
