Pseudocercospora

Pseudocercospora is a genus of ascomycete fungi. An anamorphic version of the genus Mycosphaerella, Pseudocercospora species are plant pathogens, including the causal agent of the so-called South American leaf blight of the rubber tree.^[1] The widely distributed genus is concentrated predominantly in tropical regions.^[2] Pseudocercospora was circumscribed by Italian-Argentinian botanist Carlos Luigi Spegazzini in 1910.^[3]
