gen. et. sp. nov. (Pleosporales, Dothideomycetes) from medicinal plants in northern Thailand.

, a new genus, is introduced with its type species, , which was isolated from withered twigs of two medicinal plants, (Blanco) Merr (Verbenaceae) and (Hook.f.) Ridl (Rubiaceae) in northern Thailand. The genus is characterized by mononematous, septate, brown or dark brown conidiophores, monotretic conidiogenous cells and catenate, obclavate, olivaceous to blackish brown conidia. Phylogenetic analysis of combined LSU, SSU, -α, and ITS sequence data showed forms a distinct phylogenetic lineage in Pleosporales, Dothideomycetes. Therefore, we treat as Pleosporales genera based on morphology and phylogenetic analyses. Descriptions and illustrations of the new taxa are provided, and it is compared with morphologically similar genera.
