Type.
Australia • Queensland, Bongeen, from the peduncle of Zea mays (Poaceae), 25 Feb. 2016, B. Thrift (holotype: BRIP 64547 d, ex-type: CBS 150772).
Description.
Conidiophores borne on aerial mycelium, 8.5–98 um tall, unbranched, sympodial, bearing terminal or lateral phialides, often reduced to single phialides; aerial phialides mono- and polyphialidic, subulate to subcylindrical, proliferating percurrently, smooth- and thin-walled, 4–22 × 1.5–5 μm, with inconspicuous thickening; aerial conidia mostly fusiform, slender, curved dorsiventrally, no apparent tapering observed at ends, blunt to conical and straight to slightly curved apical cell and a blunt to papillate basal cell, 0–3 - septate, 0 - septate conidia: 7–22 × 2–5 μm (av. 15.0 × 3.4 μm) (n = 9); 1 - septate conidia: 12–19 × 2.5–4 μm (av. 15.6 × 3.4 μm) (n = 13); 2 - septate conidia: 16–20 × 3.5–4 μm (av. 18.2 × 3.8 μm) (n = 2); 3 - septate conidia: 21–31 × 3.5–4 μm (av. 23.9 × 3.9 μm) (n = 6). Sporodochia pale yellow to white, formed between aerial mycelia around the carnation leaves. Sporodochial conidiophores densely and irregularly branched, bearing apical whorls of 2–3 phialides; sporodochial phialides monophialidic, subulate to subcylindrical, 6–12 × 1.5–4 μm, smooth, thin-walled, with inconspicuous periclinal thickening; sporodochial conidia falcate, curved dorsiventrally, tapering towards both ends, with a slightly curved apical cell and a blunt to foot-like basal cell, (1 –) 3–5 - septate, hyaline, smooth- and thin-walled; 1 - septate conidia: 12–17 × 3 μm (av. 14.4 × 3.2 μm) (n = 2); 3 - septate conidia: 19–36 × 3 × 4 μm (av. 30.0 × 3.8 μm) (n = 23); 4 - septate conidia: 30.5–36 × 4–5 μm (av. 33.2 × 4.3 μm) (n = 4); 5 - septate conidia: 30 × 5 μm (n = 1). Chlamydospores not observed.
Culture characteristics.
Colonies on PDA incubated at 25 ° C in the dark with an average radial growth rate of 1–15 mm / d and occupying an entire 90 mm Petri dish in 7 d; surface white, radiate, aerial mycelium felty to velvety, margin irregular, filiform. Additional colony diam (after 7 d, in mm): PDA at 10 ° C 14–19; PDA at 15 ° C 37–43; PDA at 20 ° C 63–70; PDA at 30 ° C 40–75; PDA at 35 ° C 0–2. Odour absent. Reverse pale yellow. Diffusible pigments absent. On OA in the dark, occupying an entire 90 mm Petri dish in 7 d; surface white, flat, slightly felty to velvety, aerial mycelium scant, margin irregular, filiform. Reverse pale luteous, without diffusible pigments. On SNA with sparse aerial mycelium, sporulation moderate on the surface of the medium.

Notes.
Fusarium goeppertmayerae belongs to the Incarnatum - clade and is closely related to the undescribed Fusarium FIESC 22 isolated from the human sinus cavity (O’Donnell et al. 2009) and F. sylviaearleae isolated from a leaf lesion of Sporobolus natalensis (Poaceae) (Tan and Shivas 2023). No morphological data are available for Fusarium FIESC 22 or F. sylviaearleae. Furthermore, we demonstrate that strains NRRL 32865 and NRRL 13335, previously considered to belong to F. guilinense, belong to F. goeppertmayerae, with F. guilinense (LC 12160 T) a distant relative.
