 Fig. 1 5-day-old colony on PDA  Fig. 2 Fusarium longipes. a. Microconidia. b, c. Chlamydospores. (Bars= 5 μm, unless otherwise specified) |
| Colonies |
Colonies on PDA attaining 52-mm at 25 °C after 5 days, sparsely cottony, aerial mycelia pale red-violet at the center, paler toward the edge, with aerial mycelia often turning pale brown with age, reverse similar. |
| Conidia |
Macroconidia not observed. Microconidia scanty, aseptate, hyaline, ellipsoidal to obovoid, 4.5–10 × 2.0–2.5 µm |
| Chlamydospores |
Chlamydospores abundant on WA, OA, SNA, submerge, globose or ellipsoid, single, mostly intercalary, 10–22 × 5–20 µm. |
| Note |
This species is characterized by the long macroconidia with whip-like apical cells and protruding foot cells. Strain 14026 shares 100% and 99.69% identities in ITS and EF1a regions with Fusarium longipes NRRL 20695 (PXOG01000084, GQ915509). This species is supposed to produce a large number of aerial conidiophores (with microconidia) on PDA and SNA, and abundant sporodochia (with macroconidia) on CLA (Maryani et al.,2019). However, strain 14026 only produced sparse microconidia on these media. |
| Pathogenicity |
This species has been found on banana (Musa spp.) and rice, but is not considered to be pathogenic (Maryani et al., 2019; Pak et al., 2017). |
