Notes.

Synnemasporella aculeans was proposed as a new combination in the new genus Synnemasporella based on the description of Cryptodiaporthe aculeans ( Fan et al. 2018), which was introduced producing perithecial ascomata, and an asexual morph producing sporodochial and/or pycnidial conidiomata ( Wehmeyer 1933). In the present study, five isolates from canker tissues on Rhus chinensis were congruent with S. aculeans based on morphology and DNA sequences data. This was the first time that the sexual morph of Synnemasporella aculeans in China had been collected.
