Diaporthe donglingensis Y.K. Bai & X.L. Fan, Plant Pathol. 71: 1982 (2022).

Description.

See Bai et al. (2022).

Specimens examined.

China, Beijing City, Mentougou District, Mountain Dongling , Xiaolongmen Forestry Centre , 40°0'54.47"N, 115°29'36.24"E, on twigs and branches of Corylus heterophylla , 13 Jun 2022, Y.K. Bai & X.L. Fan (BJFC CF202212148, cultures CFCC 58806 and 58807) .

Notes.

Diaporthe donglingensis was isolated from Corylus heterophylla in Beijing, China ( Bai et al. 2022). Phylogenetically, isolates CFCC 58806 and 58807 clustered together with D. donglingensis with high statistical support (ML/BI = 100/1.00) (Fig. 1 ). Therefore, two isolates in this study were confirmed to be D. donglingensis .

Figure 1. Phylogenetic tree of Diaporthe resulting from a Maximum-Likelihood (ML) analysis, based on the concatenated sequences from ITS, cal, his 3, tef 1 - α and tub 2 genetic regions. Numbers above the branches indicate ML bootstraps (left, ML BS ≥ 50 %) and Bayesian posterior probabilities (right, BPP ≥ 0.90). The tree is rooted with Diaporthella corylina CBS 121124. Isolates from the present study are marked in blue and holotype isolates are indicated in bold.
