No aerial phialides or conidia were observed for the closely related species (Wang et al. 2019; Xia et al. 2019; Afzalinia et al. 2024) compared to the few scarce monophialides we recorded for  F. cumulatum . Sporodochia and chlamydospores were present in  F. cumulatum and its closely related species, whereas  F. oryzicola lacked chlamydospore formation (Wang et al. 2019; Xia et al. 2019; Afzalinia et al. 2024). Sporodochial conidia of  F. cumulatum (1–5 - septate; 16–57 × 2.5–4 μm) are similar in length to  F. arcuatisporum (5 - septate; 29–49.5 × 4–6 μm) (Wang et al. 2019) and  F. brevicaudatum (1–5 - septate; 8–64 × 3–5 μm) (Xia et al. 2019), while generally being shorter than those observed in  F. khuzestanicum (4–7 (– 9) - septate; 48.5–82 × 2.7–4.3 μm) (Afzalinia et al. 2024),  F. longicaudatum ((3 –) 5–6 (– 7) - septate; 45–81 × 4–5 μm) (Xia et al. 2019) and  F. oryzicola (4–7 - septate; 33.5–77.9 × 3–4 μm) (Afzalinia et al. 2024). Colony colour on PDA differs between  F. cumulatum and closely related species (Wang et al. 2019; Xia et al. 2019; Afzalinia et al. 2024) as other species show more colour across the surface and reverse compared to the white surface and yellowish white (2 A 2) reverse of  F. cumulatum, whereas the colony colour of  F. khuzestanicum and  F. oryzicola is white to pale grey. The growth rate after 7 d on PDA for  F. cumulatum (44–46 mm) is slower than that of  F. arcuatisporum (48–53 mm) (Wang et al. 2019),  F. brevicaudatum (50–58 mm) (Xia et al. 2019) and  F. longicaudatum (full 90 mm plate) (Xia et al. 2019). The growth rate for  F. khuzestanicum (74–76 mm) (Afzalinia et al. 2024) and  F. oryzicola (74 mm) (Afzalinia et al. 2024) was measured after 5 d on PDA but appears to be faster than that of  F. cumulatum . No morphological data is currently available for  F. heslopiae to compare with. Pairwise comparisons revealed that  F. cumulatum differs from other species by at least 3, 6 and 16 bp for CaM, RPB 2 and TEF, respectively.</p></div>	https://treatment.plazi.org/id/124430B7210F57BE8B3FFE27B80C84AA	Public Domain	No known copyright restrictions apply.

(Khuna et al. 2022),  F. irregulare (FIESC 15) (Wang et al. 2019),  F. luffae (FIESC 18) (Wang et al. 2019),  F. mianyagense (Han et al. 2023),  F. multiceps (FIESC 19) (Xia et al. 2019),  F. pernambucanum (FIESC 17) (Santos et al. 2019) and  F. sulawesiense (FIESC 16) (Maryani et al. 2019).  Fusarium mariecurieae produces both aerial mono- and polyphialides compared to  F. irregulare that only produces monophialides (Wang et al. 2019),  F. luffae that produces only polyphialides (Wang et al. 2019) and  F. mianyagense that lacks aerial phialides (Han et al. 2023). Aerial conidia from  F. mariecurieae (0–3 (– 5) - septate; 8–30.5 × 3–5 μm) are smaller than that of  F. irregulare (mostly 3 - septate; 16–38.5 × 3–5 μm) (Wang et al. 2019),  F. luffae (3–5) - septate; 26.5–46 × 4–5 μm) (Wang et al. 2019),  F. multiceps (1 –) 3–4 (– 5) - septate; 16–37 × 3–4 μm) (Xia et al. 2019),  F. pernambucanum (1–7) - septate; 7–57 × 2.5–5 μm) (Santos et al. 2019) and  F. sulawesiense (3–5 (– 9) - septate; 20.5–67 × 3.5–6 μm) (Maryani et al. 2019).

Sporodochia were absent from  F. citrullicola,  F. irregulare and  F. luffae (Wang et al. 2019), while chlamydospores were absent from  F. irregulare,  F. luffae,  F. mianyagense,  F. multiceps and  F. sulawesiense (Maryani et al. 2019; Wang et al. 2019; Xia et al. 2019; Han et al. 2023). Sporodochial conidia from  F. mariecurieae (1–3 (– 5) - septate; 12–36 × 3–5 μm) were smaller than that of  F. caatingaense (1–5 - septate; 15–50 × 2–4.5 μm) (Santos et al. 2019),  F. mianyagense (3 (– 5) - septate; 24.5–36.6 × 2.5–4.9 μm) (Han et al. 2023),  F. multiceps ((1 –) 2–5 - septate; 16–46 × 3–4 μm) (Xia et al. 2019) and  F. sulawesiense ((3 –) 5 (– 6) - septate; 29.5–43.5 × 4–5.5 μm) (Maryani et al. 2019).

The growth rate after 7 d on PDA for  F. mariecurieae is faster (&gt; 90 mm plate) than that of  F. citrullicola (68–74.5 mm) (Khuna et al. 2022),  F. irregulare (53–59 mm) (Wang et al. 2019),  F. luffae (53–57 mm) (Wang et al. 2019) and  F. mianyagense (74–80 mm) (Han et al. 2023). The growth of  F. multiceps (&gt; 90 mm plate) (Xia et al. 2019) is similar to that of  F. mariecurieae, while the growth rate in terms of diameter was not reported for  F. caatingaense,  F. pernambucanum and  F. sulawesiense (Maryani et al. 2019; Santos et al. 2019).

Reverse yellowish white (3 A 2). Diffusible pigments absent. On SNA with sparse aerial mycelium, sporulation moderate on the surface of the medium.</p><p>Additional materials examined.</p><p>South Africa • Eastern Cape, from mixed pasture samples, May 2020, collected by A. Davis, isolated by C. Dewing,  Humansdorp area: CMW-IA 003320 = CMW 61364 = CN 056 A 8, CMW 58649 = CN 070 E 7, CMW 58650 = CN 070 F 7, CMW-IA 002133 = CMW 60931 = CN 070 I 3, CMW 58651 = CN 070 I 4, CMW 58652 = CN 071 B 8, CMW 58654 = CN 071 D 3, CMW 58655 = CN 071 E 9, CMW 58662 = CN 104 D 6, CMW 58663 = CN 104 D 7 ,   close to Kou-Kamma: CMW 58656 = CN 071 F 9 ,   Outside Humansdorp,  close to Clarkson: CMW 58657 = CN 071 G 8, CMW 58660 = CN 071 I 9, CMW 58661 = CN 072 A 1 ,   close to Tsitsikamma on Sea: CMW 58658 = CN 071 I 3, CMW 58659 = CN 071 I 5  .</p><p>Notes.</p><p>Fusarium pascuum belongs to the  Camptoceras - clade (as introduced by Han et al. (2023)) and is closely related to  F. fecundum . Both  F. pascuum and  F. fecundum produce aerial mono- and polyphialides. Aerial conidia from  F. pascuum (0–3 - septate; 7–32 × 2–6 μm) are comparably smaller than those of  F. fecundum ((1 –) 2–4 (– 6) - septate; 3.6–35.8 × 3.6–6.8 μm) (Han et al. 2023). Sporodochia and chlamydospores are absent in both  F. pascuum and  F. fecundum . Colony colour on PDA differs between  F. pascuum and  F. fecundum, where the former is completely white across the surface and the latter is greyish yellow in the centre, while the reverse of  F. pascuum is yellowish white and  F. fecundum is just white (Han et al. 2023). The growth rate after 7 d on PDA in  F. pascuum (reaching 80 mm) is slightly slower than that of  F. fecundum (84–90 mm) (Han et al. 2023). Pairwise comparisons revealed that  F. pascuum differs from other species by at least 8, 8 and 23 bp for CaM, RPB 2 and TEF, respectively.</p></div>	https://treatment.plazi.org/id/16A91355E27352B7A936E46F714C5C80	Public Domain	No known copyright restrictions apply.
