| Figure |  Fig. 1 5-day-old colony on PDA  Fig. 2 Fusarium spinosum. a, b, g. Conidiophores and conidia. c. Sporulation in culture. d, e. Conidia. f. Chlamydospores (Bars= 5 μm, unless otherwise specified) |
| Colonies | Colonies on PDA attaining 62-mm at 25 °C after 5 days, cottony, red-violet, azonate, margin entire, reverse initially pale brown, turning red-violet from the center with age. |
| Sporodochia | Sporodochia not observed on PDA, CLA, OA, WA. |
| Conidiophores | Conidiophores macronematous, erect, hyaline or pale red-violet, smooth or verrucose, simple or repeatedly branched, terminating in 1–3(–4) conidiogenous cells. |
| Conidiogenous cells | Conidiogenous cell hyaline, terminal or intercalary, phialidic, often with sympodial proliferation, with 1–6 conidiogenous loci. |
| Conidia | Conidia borne on aerial conidiophores, abundant in culture, hyaline, obovoid, 0–1-septate, 5.5–10(–13) × 2.5–4 µm. |
| Note | This species was recently proposed by Lombard et al. (2019) to separate phylogenetically closedly related F. chlamydosporum species complexes 3-a (O’Donnell et al., 2009), and is characterized by producing only aerial sympodial conidiophores without sporodochia (macroconidia).
Strain 14023 shares 99.48% identity in EF1a with the ex-type strain of Fusarium spinosum (CBS 122438, MN120768). Conidia of strain 14023 is shorter and has only 0–1-septate, which is slightly different from the description (0–3-septate) provided by Lombard et al. (2019). |
