Neocamarosporium betae is a plant pathogen infecting Beta vulgaris (beet) and causes Phoma leaf spot. It was originally published and described in 1877 as Pleospora betae before being resolved as Neocamarosporium betae (Berl.) Ariyaw. & K.D. Hyde in 2015.^[2]^[3] It also causes leaf spot on Spinach plants.^[4]

It contains the chemical substances betaenone A,^[5] B and C. Pleospora betae develops on dead beet residues and is a marsupial stage of the Phoma betae anamorph, parasitizing on beets and causing a number of harmful diseases.
