Conidiophores on aerial mycelium originating erect and prostrate from substrate; they are sympodially branched bearing mono and polyphialides.

[3][4][5] It causes mango malformation disease (MMD) and induces vegetative development abnormalities in shoots that leads to misshaped buds, short internodes, dwarf and narrow leaves.

Moreover, MMD causes hormone imbalances in the inflorescence that leads to abnormalities [6] such as an increase in size and numbers, especially for male flowers.

It is an ascomycete that produces mycelia with aerial conidiophores that contain colored structures such as macroconidia with up to five cells, microconidia in false heads and a sporodochium.

Small fruits have also been found to be sources of inoculum in the outer flesh but not the seeds[10] contributing to the spread of the fungus if moved from infected orchards.

[2] Although inoculum is high during the summer, MMD spreads slowly in orchards due to the sensitivity of conidia to sunlight that impedes their survival.

[10] Under experimental conditions, sprays with concoctions containing extracts from Datura stramonium, Calotropis gigantea and Azadirachta indica (neem), showed antifungal activity and controlled the malformation symptoms on mango.
