Pseudocercospora diospyricola is a fungal species in the family Mycosphaerellaceae, order Capnodiales, class Dothideomycetes, phylum Ascomycota. It causes leaf spot disease on persimmon (Diospyros spp.). In East and Central Texas, Pseudocercospora diospyricola has been isolated from native and cultivated persimmon, with symptoms including circular to irregular brown lesions on leaves, often surrounded by a yellow halo. The fungus overwinters on infected leaf debris and produces conidia that infect new foliage during warm, humid weather.

Black blotches on leaves of persimmon caused by Cercospora leaf spot fungus Pseudocercospora diospyricola under a microscope, collected in Bee Creek Park. College Station, Texas, August 31, 2023Observations of the fungus Pseudocercospora diospyricola in East and Central Texas revealed distinct symptoms on persimmon leaves. Necrotic spots developed into angular lesions on the underside of leaves, while black blotches formed on both the upper and lower surfaces. Infected leaves often turned yellow prematurely, with visible black spots. These symptoms were consistently observed across multiple locations, including Sam Houston National Forest, Lick Creek Park, and Bee Creek Park, over several years (2020-2023). Microscopic examination of infected leaves collected in Bee Creek Park confirmed the presence of black blotches caused by Pseudocercospora diospyricola. The fungus was found to cause similar damage on persimmon leaves throughout the region, with black blotches being a characteristic feature of the infection.
