Ciri dan struktur
The colonies of C. pallescens differ in morphology depending on the growth medium used. On Czapek Yeast Extract Agar (CYA), colonies of C. pallescens are 50-65mm in diameter. On Malt Extract Agar (MEA), the colonies are fuzzy in texture, and pale grey to grey in colour. On the reverse side, they appear brown to dark brown. The colonies rapidly cover the entire Petri dish. On G25N, the colonies of C. pallescens are 3–6 mm in diameter, and appear grey and brown in colour. On Dichloran Chloramphenicol Malt Agar (DCMA), the colonies are 50–65 mm in diameter, and pale brownish-grey in colour. Lastly, colonies of C. pallescens grown on Phenylethyl Alcohol Agar (PEA) appear woolly at the centre. The conidiophores of C. pallescens are rarely branched, and are brown in colour. They can appear slightly bent at the apices, but otherwise they are predominately straight. The dimensions of the conidiophore vary, especially concerning its length. They can be up to 6μm wide. The conidia of C. pallescens are rugby or gridiron football- to bean-shaped, and are less curved than those of related species. They appear smooth in texture, and pale-brown to brown in colour. The three septa within each conidium give rise to four cells. The third cell from the base appears swollen in comparison to the surrounding cells. The dimensions of the conidia are 18-25 x 9-12 μm. Cochliobolus pallescens is the teleomorphic form of Curvularia pallescens. It produces spherical ascomata that are black in colour. On the surface of the ascomata, there are protruding colourless necks from which the ascospores emerge.
Habitat dan peran ekologis
Curvularia pallescens is commonly found in tropical regions, such as India. They usually grow on unharvested crops (i.e., crops that have not been dried or stored), such as grass, rice, wheat, maize, and sorghum. Optimal growth occurs at 25-30 °C, and at an aw of 0.976. The minimum aw for growth is 0.89. Germination occurs at 0.855 aw but does not result in the establishment of colonies. Sulphur and phosphorus are macronutrients involved in the production of DNA, RNA and proteins in fungal species. It has been reported that C. pallescens is able to grow and sporulate in the absence of both. Magnesium sulphide and tripotassium phosphate support the growth and sporulation of C. pallescens whereas, ammonium sulphate and ammonium phosphate do not.

Melihat dengan konteks
Skema konidium Curvularia pallescens berbentuk menyerupai kacang, berpermukaan halus, dan berwarna cokelat pucat–cokelat. Tiga sekat membentuk empat sel; sel ketiga dari pangkal lebih membengkak. Tidak berskala; tingkat kelengkungan serta proporsi antarsel disederhanakan, bukan rekonstruksi satu spesimen.
