| Figure |  Fig. 1 5-day-old colony on PDA  Fig. 2 Curvularia verruculosa. a, d, e. Conidiophores and conidia. b, c. Conidia (Bars= 5 μm, unless otherwise specified) |
| Colonies | Colonies on PDA attaining 45-, 61-, 0-mm at 24 °C, 28 °C and 37 °C after 5 days, margins entire, floccose, reverse dark with white margin. |
| Conidiophores | Conidiophores macronematous, light brown, flexuous, septate, simple or branched, up to 500 µm, 3.5–5 µm wide. |
| Conidiogenous cells | Conidiogenous cells integrated, terminal or intercalary, geniculate, sympodial. |
| Conidia | Conidia smooth, straight or slightly curved, fusiform with rounded ends, clavate, ellipsoid or fusiform, with inconspicious hilum, pale brown to brown, mostly concolorous, third cell sometimes slightly darker and larger, verruculose except the apical cell, mostly 3-septate , 24–28 × 9–11 µm. |
| Note | Strain 12053 has narrower conidia in comparison with the epitype strain of Curvularia verruculosa CBS 150.63 (9–11 µm vs. 12–16 μm) (Su et al. 2015). The similarities between both strains in the ITS, GPD, and EF1a regions are 99.78%, 99.76%, and 99.77%, respectively.
This species is morphologically similar to Curvularia americana, but can be clearly distinguished by the differences in ITS and GPD sequences. |
| Pathogenicity | This species has been reported to infect rice leaves and spikelets in India (Aulakh, 1966). |
