Notes: Botryosphaeria kuwatsukai (LSP 5, CBS 135219) and B. rosaceae (CGMCC3.18008, CGMCC3.18007) show close phylogenetic affinity (Li et al. 2018, and this study). The ITS and tef1 sequences of these two taxa are 100 % similar excluding the beginning and end where there are no base pairs to compare. Morphologically, B. kuwatsukai shows similar form of conidia and paraphyses to B. rosaceae (note: the conidiomata of B. kuwatsukai are not mentioned in detail in Xu et al. (2015) and cannot be compared). Based on above facts, B. kuwatsukai is regarded as conspecific with B. rosaceae. Because B. kuwatsukai has a priority, B. rosaceae is reduced as synonym of B. kuwatsukai.
