Description.

See Yang et al. (2021a).

Specimens examined.

China, Jiangxi Province: Ganzhou City , on branches of Citrus maxima , 11 May 2018, Q. Yang, & Y.M. Liang (BJFC-S1615; living cultures: CFCC 53098, CFCC 53099, and CFCC 53100) .

Notes.

Diaporthe multiguttulata is characterised by ellipsoidal alpha conidia with one large guttulate, and was originally described as an endophyte from healthy branch of Citrus grandis in Fujian Province, China ( Huang et al. 2015). Yang et al. (2021a) identified three isolates from Citrus maxima as D. multiguttulata based on DNA sequence data and confirmed from the morphological characters. In the present study, isolates (CFCC 53098, CFCC 53099, and CFCC 53100) from an additional specimen were observed and supplemented with beta conidia (Fig. 4j ).
