Notes: For comments about the F. graminearum s. lat. clade see notes under F. acaciae-mearnsii and F. graminearum. Although resolved by phylogenetic and STACEY analyses, F. cortaderiae is morphologically indistinguishable from its closest phylogenetic sibling F. brasilicum, both species forming asymmetric, straight to curved, 4.5–5 µm wide, 5-septate conidia, with narrow apical beaks, and wider below the median (Aoki et al. 2012). Moreover, both species overlap in their host preferences and partially in their biogeographic patterns; however, F. cortaderiae has a wider geographical distribution, with additional records in Europe (Italy), Oceania (Australia and New Zealand) and South America (Argentina, Brazil, and Uruguay), apart from Africa (South Africa) (Farr et al. 2023). In addition, unlike F. brasilicum, known only from a restricted number of Poaceae hosts (Avena sativa, Hordeum vulgare, and Triticum sp.), F. cortaderiae is known from Asteraceae (Gerbera sp.), Caryophyllaceae (Dianthus sp.), Fabaceae (Glycine max), Poaceae (Cortaderia selloana, Hordeum vulgare, Lolium multiflorum, Oryza sativa, Triticum aestivum, Triticum durum, and Zea mays), and soil (Farr et al. 2023)
