Abstract

During our biodiversity investigations in Tibet, China, typical Cytospora canker symptoms were observed on branches of hosts Myricaria paniculate, Prunus cerasifera and Sibiraea angustata. Samples were studied, based on morphological features coupled with multigene phylogenetic analyses of ITS, act, rpb2, tef1 and tub2 sequence data, which revealed two new species (Cytospora myricicolasp. nov. and C. sibiraeicolasp. nov.) and a known species (C. populina). In addition, Cytospora populina is newly discovered on the host Prunus cerasifera and in Tibet.
