Extract from Wikipedia article: Coleosporium ipomoeae is a plant pathogen. Specifically, it is a fungus that can develop on sweet potatoes.
Coleosporium ipomoeae is a rust fungus that infects plants in the Convolvulaceae family, particularly sweet potato and morning glory. In East and Central Texas, it has been found to cause disease on Ipomoea species, resulting in yellow or orange spores on the underside of leaves. The fungus is typically active from May to October, with peak activity during the summer months. It overwinters as teliospores on infected plant debris and can be dispersed by wind and water.
