Golovinomyces latisporus is a fungal plant pathogen in the family Erysiphaceae (powdery mildews). Part of the Golovinomyces ambrosiae complex, this species infects sunflowers (Helianthus, and likely Heliopsis too).
Golovinomyces latisporus was first described by Uwe Braun in 1983 with the basionym Erysiphe cichoracearum var. latispora. The variety was later raised to species level by Peng-Lei Qiu et al. in 2020.
