Curvularia inaequalis is a plant saprobe[1] that resides in temperate and subtropical environments.

[3] The species has been observed in a broad distribution of countries including Turkey, France, Canada, The United States, Japan and India.

[7] The fungus was isolated from diseased New Jersey cranberry pulp[7] and termed Helminthosporium inaequale.

[2] Instead, sequencing of nuclear rRNA internal transcribed spacer regions (ITS) can be done to achieve accurate identification.

[13] In its active form, the enzyme is able to then produce hypochlorous acid, a strong oxidizing agent.

[5] It has been theorized that C. inaequalis utilizes chloroperoxidase and hypochlorous acid in combination to penetrate the host's cell wall.

The species is able to produce large amounts of β-galactosidase, which can hydrolyze lactose in acid whey.

[10][15] Symptoms of infection by C. inaequalis include the combination of oval shaped dark brown patches and leaf tip dieback.

[2] Furthermore, a case of recorded aerosolized C. inaequalis in one Canadian home supports airborne movement of spores as an important mode of transfer.

[2] While many cases of infection due to soil contact with the genus Curvularia, connection with the specific species has not yet been confirmed.
