| Figure |  Fig. 1 5-day-old colony on PDA  Fig. 2 Fusarium tanahbumbuense. a, b, g. Conidiophores, conidiogenous cells and conidia. c. Conidia. d. Microconidiation. e. Sporodochia on CLA. f. Aerial phialides. h. Aerial conidiophores on SNA. (Bars= 5 μm, unless otherwise specified) |
| Colonies | Colonies on PDA attaining 47-mm at 25 °C after 5 days, cottony, elevated, azonate, margin entire or undulate, white, turning pale yellow from the center with age, reverse similar, with diffuse pale brown pigment. |
| Sporodochia | Sporodochia abundant in old culture (>3 wks) on PDA, OA and SNA, pale brown, aerial, superfical or submerged. |
| Conidiogenous cells | Sporodochial phialides flask-shaped or elliptical, monophialidic, tapering towards the apex, hyaline, lateral or terminal, often in whorls of 2–6, 7–12 × 2.5–4 µm. Aerial phialides flask-shaped or elliptical, mostly single, often polyphialidic, 11–19 × 3–4 µm. |
| Conidia | Macroconidia hyaline, falcate, with a foot-shaped basal cell, (2–)3-septate, (21–)27–34(–36) × (2.5–)3–3.5 µm. Microconidia not observed. |
| Note | This species was recently proposed by Maryani et al. (2019) to separate phylogenetically closely related Fusarium incarnatum-equiseti species complexes 24 (O’Donnell et al., 2009), and is characterized by producing aerial macroconidia from branched conidiophores, which will turn into aerial sporodochia with age and without microconidia.
