Bipolaris papendorfii is a dematiaceous fungus belonging to the order Pleosporales in the class Dothideomycetes. B. papendorfii UM 226 was isolated from the skin scraping sample of a patient. B. papendorfii is a rare opportunistic pathogen as compared to the three well-known pathogenic species: Bipolaris australiensis, Bipolaris hawaiiensis and Bipolaris spicifera. B. papendorfii is also causal agent of corn leaf spot in China. Bioactive compounds: hamigerone and radicinol that were extracted from B. papendorfii were found to have anti-proliferative activity.


The surface of the colonies was initially grayish white to olive green and becomes to black. The colony becomes mature in 5 days growing on Sabouraud Dextrose Agar (SDA) and a raised grayish periphery was observed. Colonies are effuce and velvety. Conidiophores are simple or branched, flexuose with zigzag rachis bearing conidium in a sympodial pattern. Conidia are curved and kidney-shaped, which usually broadest at the second cell from the base.
