Lasiodiplodia gilanensis is an endophytic fungus. It was first isolated in Gilan Province, Iran, hence its name. It has since been isolated in other plants in other continents, and is considered a plant pathogen. L. gilanensis is phylogenetically related to L. plurivora, but can be distinguished by its conidial dimensions. Also, the paraphyses of the former are up to 95μm long and 4μm wide, whereas those of L. plurivora are up to 130μm long and 10μm wide. At the same time, the basal 1–3 cells in the paraphyses of L. plurivora are broader than its apical cells.
