Dothiorella viticola on Populus cathayana in China: a new record

We document the first report of the species Dothiorella viticola (teleomorph: Spencermartinsia viticola) from China. This fungus was isolated from the bark of Populus cathayana collected from Qianyang, Shaanxi Provinces. Morphological characteristics of the anamorph indicated that it was a Dothiorella species, and phylogenetic analysis based oil rDNA-ITS data confirmed that the isolate should be included within Spencermartinsia. Conidiogenesis, observed ill pycnidia obtained in culture, was holoblastic with conidiogenous cells proliferating at the same level giving rise to periclinal thickenings. Conidia were brown, thick-willed and septate with both ends rounded or with a truncate base.
