  A pathogenic fungus was isolated from soursop imported from Thailand, which was identified as Pestalotiopsis sp.based on the morphological characteristics of the colony and conidia of the fungus, and the alignment of ITS sequences.Diseased fruits showed physalospora-shaped, black depression and small black spores heap on the lesion surface.The conidium separated 5-cellularia, longefusiformia,curvata, (15.6 ~22.2) μm x (4.8 ~7.1) μm.The middle three cells are dark brown.Both ends of the cell are light color.The ITS sequence of the fungus was obtained by PCR and sequenced.The result of sequencing shows a 99% ~ 100% identity with Pestalotiopsis sp.
