Description.

see Hou et al. (2020 b).

Materials examined.

China, Zhejiang Province, Hangzhou City, from healthy leaves of C. sinensis cv. Longjing 43, 16 Nov. 2017 Y. C. Wang, culture ex-type CGMCC 3.24251 = YCW 1346 .

Notes.

Neoascochyta mortariensis was introduced as Didymella graminicola previously. It was described as a new species in Neoascochyta , distant from the authentic culture of D. graminicola (currently: Neoascochyta graminicola ) ( Hou et al. 2020 b). Neoascochyta mortariensis was first isolated from Oryza sativa in Italy and formed colonies on PDA covered by dense felty aerial mycelium ( Hou et al. 2020 b). It formed a distinct lineage closely related to N. tardicrescens (Fig. 4 ). In the present study, one strain was isolated from diseased tea plant leaves. This is the first report of N. mortariensis isolated from C. sinensis .

Figure 4. Phylogenetic tree generated by Maximum Likelihood analysis, based on the combined ITS, LSU, RPB 2 and TUB 2 dataset of Neoascochyta, Paraboeremia, Remotididymella and Stagonosporopsis species. Bootstrap support values above 50 % and Bayesian posterior values above 0.75 are shown at each node (ML / PP). Pleiochaeta setosa CBS 118.25 / CBS 496.63 is used as the outgroup. Ex-type strains are emphasised in bold.
