Fusarium mangiferae is a fungal plant pathogen [1] that infects mango trees. [2] Its aerial mycelium is white and floccose. Conidiophores on aerial mycelium originating erect and prostrate from substrate; they are sympodially branched bearing mono and polyphialides. Polyphialides have 2–5 conidiogenous openings.

The disease initially presents as small dark brown or gray spots on the underside of leaves or fruit. These spots enlarge and darken over time, developing a velvety or cracked texture in the center of the lesion. [2]
Leaf spots can vary in size, shape, and color depending on the age and type of the cause or pathogen.
