| Figure |  Fig. 1 5-day-old colony on PDA  Fig. 2 Curvularia geniculata. a–c. Conidiophores and conidia. d. Stromata on PDA. e. Conidia  Fig. 3 Colony, sporulation on PDA, conidia, stromata in different strains(Bars= 5 μm, unless otherwise specified) |
| Colonies | Colonies on PDA attaining 57-, 63-, 15-mm at 24 °C, 28 °C and 37 °C after 5 days, margins entire, floccose, reverse initially white with brown pigment, black, slightly zonated when older. |
| Conidiophores | Conidiophores macronematous, mostly arising from creeping hyphae, brown, flexuous, septate, simple, up to 400 µm, 2–5 µm wide. |
| Conidiogenous cells | Conidiogenous cells integrated, terminal or intercalary, geniculate, sympodial, with darkened and thickened conidial scars. |
| Conidia | Conidia straight or curved, pale brown, the third cell from the base often darker and larger than the others, with slightly protuberant hilum at the base, 3-4 septate(mostly 4), 20–28 × 6.5–10 µm. |
| Note | This species is widespread, and commonly occurs in soil and on decayed plant tissue. It is pathogenic to many plant species, and opportunistically pathogenic to animals and also humans. Characteristic cylindrical stromata usually produced and erected on old cultures. |
| Pathogenicity | This species is considered to be one of the major pathogens that cause the black kernel, sometimes infecting leaves to cause leaf spots (Ou, 1985). |
