Phomopsis longicolla
Phomopsis longicolla is a species of ascomycete fungus in the family Diaporthaceae. It is a plant pathogen and mainly responsible for a soybean disease called "Phomopsis" seed decay (PSD). In other plant species, "P. longicolla" can also live as an endophyte, such as in the mangrove plant "Sonneratia caseolaris". "P. longicolla" has been found to produce a number of cytotoxic and antimicrobial secondary metabolites, especially members of the class of phomoxanthones. "P. longicolla" was first described in 1985 by Thomas W. Hobbs "et al." at the Department of Plant Pathology at Ohio State University.
