Curvularia geniculata is a fast-growing anamorphic fungus in the division Ascomycota, most commonly found in soil, especially in areas of warmer climates.

[1][3] C. geniculata is characterized by its curved conidia, which has a dark brown centre and pale tapered tips,[4] and produces anti-fungal compounds called Curvularides A-E.[5] The fungus was discovered by American botanist Samuel Mills Tracy and mycologist Franklin Sumner Earle in Starkville, Mississippi 1894 on Love grass (Eragrostis rachitricha) grown from imported seeds.

[5] Curvularia geniculata colonies grown on Oxford agar can grow rapidly to 3–5 cm in diameter, with a dark brown and hairy appearance.

[1] The fungus produces conidiophores up to 600 μm long, becoming lighter near the tip, and are septate, meaning the structure is subdivided by walls called septa.

[2] The conidiophores will produce 4-septate[1] conidia (18–37 x 8–14 μm),[1] consisting of a curved, broad central section that is dark brown[4] and paler tapered ends.

[2] The fungus was found to be associated with many plant species within the families Amaranthaceae, Apiaceae, Araceae, Asteraceae, Balsaminaceae, Basellaceae, Brassicaceae, Convolvulaceae, Fabaceae, Gesneriaceae, Marantaceae, Oleaceae, Papaveraceae, Poaceae, Solanacae, Vitaceae and Zingiberaceae.

[5] C. geniculata produces anti-fungal compounds, Curvularides A-E, which function in cyclic peptide regulation and cell wall degradation.

[4] The fungus has been identified as the common causal agent of mycetomata, a chronic fungal infection, which gives rise to pigmented nodules on the body of horses upon traumatic injury.
