| Colonies |
Colonies on PDA attaining 42-, 58-, 0-mm at 24 °C, 28 °C and 37 °C after 5 days, margins entire, floccose, reverse dark olivaceous, slightly zonated. |
| Conidiophores |
Conidiophores hyaline, pale brown near base, branched, 5–25 x 3–4 µm. |
| Conidiogenous cells |
Conidiogenous cells cylindrical, 10–20 × 2–4 µm. |
| Conidia |
Conidia hyaline, aseptate, falcate, 20–26 × 3–4.5 µm. |
| Setae |
Setae smooth or verruculose, dark brown, tapering toward tip, 3–4.5 µm wide at the base, up to 160 µm. |
| Appressoria |
Appressoria solitary or in group, bullet-shape or irregularly lobed, 7–18 × 5–7 µm. |
| Note |
This species has not been previously found on rice. It is an important plant pathogen that causes anthracnose on legumes. Strain 13053 shares 100% and 99.2% identity in ITS and ACT regions with the ex-type strain of Colletotrichm truncatum (CBS 151.35; GU227862, GU227960). |
