Pseudoplagiostoma mangiferae Dayar., Phookamsak & K. D. Hyde , Fungal Diversity 95: 121 (2019)

Synonym.

Pseudoplagiostoma diaoluoshanense Zhao X. Zhang & X. G. Zhang

Description.

See Phookamsak et al. (2019).

Distribution.

China, Hainan and Yunnan Provinces.

Ecology.

Associated with leaf blight disease of Mangifera hosts.

Notes.

Pseudoplagiostoma mangiferae was first described from Yunnan Province, China, where it was found associated with leaf blight symptoms on Mangifera sp. ( Phookamsak et al. 2019). Subsequently, Ps. diaoluoshanense was proposed based on two isolates obtained from leaf spots of Mangifera indica in Hainan, China ( Zhang et al. 2025). Phylogenetic analysis revealed that these three isolates from Mangifera hosts formed a well-supported monophyletic clade (Fig. 1 ). Notably, they exhibit only minor sequence variations, with 2 bp differences in the ITS region and no variation in the LSU region.
