Glomerella tucumanensis is a species of fungus in the family Glomerellaceae.
It has been responsible for the elimination of many commercial varieties of sugarcane.
[3][4] Glomerella tucumanensis was first described by Frits Went as Colletotrichum falcatum belonging to the family Melanconiaceae as a fungi imperfecti.
This classification remained undisputed till 1943, when Carvajal and Edgerton found the conidial state of the fungi to be identical to Physalospora tucumanensis which was described by Spegazzini in 1896, putting it the family Pleosporaceae, thereby placing it under Ascomycota.
In 1954, von Arx and Muller transferred the fungi to the genus Glomerella, where it remains today.
