Chen) Q. Chen et al. , Studies in Mycology. 87: 138. 2017 Description. see Chen et al. (2017) . Materials examined. China , Yunnan Province , Puer City , Jingdong Yizu Autonomous County , from healthy leaves of C. sinensis , 13 Jun 2020 , Y. C. Wang , culture YCW 2118 . Notes. Didymella sinensis is closely related to D. pomorum . It can be observed from different host plants in a wide range, such as Cerasus pseudocerasus ( Rosaceae ), Dendrobium officinale ( Orchidaceae ) and Urticaceae . The sexual morph was characterised by ascomata aggregated, globose to irregular, brown, small and papillate. Asci were bitunicate, clavate to short cylindrical; Ascospores were biseriate, ellipsoidal, straight to slightly curved, hyaline, apex obtuse, medianly 1 - septate ( Chen et al. 2017 ). In the present study, eight isolates from healthy tea plant leaves phylogenetically grouped with D. sinensis with high statistical support (Fig. 2 ). This is the first report of D. sinensis isolated from C. sinensis .
