A website for gardeners has put out an article on how to treat Phyllosticta fungus infections in prickly pear cacti. This spores of this fungus land on the pads and feed on it, causing spots to appear. The spots are about one to two inches wide. They are dark. The infection usually happens during humid weather. Once the weather dries up, the fungus becomes inactive. The leaves grow calluses over the spots. The article states the cactus does not die from the attack. The gardener is advised to remove and dispose of the infected areas.

“There is no recommended treatment for Phyllosticta fungus, but it can spread to other ornamental plants and removal of infected pads and plant material is suggested to prevent the disease from reaching other species.”
