Diaporthe eres Nitschke, Pyrenomyc. Germ. 2: 245, 1870.

Description.

See Udayanga et al. (2014b).

Specimens examined.

China. Beijing: Pinggu District , on branches of Populus x xiaohei , 10 July 2020, Q. Yang (CSUFT101; living cultures: CSUFTCC101, CSUFTCC102, and CSUFTCC103) .

Notes.

Diaporthe eres is the type species of the genus and was originally described by Nitschke (1870), from Ulmus sp. in Germany, which has a widespread distribution and a broad host range as an endophyte or saprobe, or pathogen causing leaf spots, stem cankers and diseases of woody plants ( Udayanga et al. 2014b). In the present study, three isolates (CSUFTCC101, CSUFTCC102, and CSUFTCC103) are embedded into the D. eres species based on DNA sequence data (Fig. 1 ). We therefore describe D. eres as a known species for this clade.
