Notes: Fusarium pseudograminearum, formerly known as F. graminearum Group 1 was the first segregate population of F. graminearum s. lat. to be formally described as a different taxon (see additional comments under F. graminearum) (Aoki & O’Donnell 1999a, b). Phylogenetically, it resolves as the nearest relative to F. dactylidis, from which it differs by producing chlamydospores and larger multiseptate conidia.Fusarium pseudograminearum is a soil-borne fungus and causes Fusarium crown rot and occasionally Fusarium head blight on small grain cereals, and has been recently evaluated as a potential quarantine pest in the EU (EFSA Panel on Plant Health et al. 2022). Although the outcome of the pest categorization indicated that it is a potential Union quarantine pest, it has not been included in the EU Commission Implementing Regulation 2019/2072 yet. It is known to affect several hosts in Fabaceae (Glycine max, and Medicago spp.), Poaceae (Aegilops tauschii, Ammophila sp., Austrostipa aristiglumis, Avena sp., Dactylis glomerata, Hordeum spp., Lolium sp., Panicum virgatum, Triticum spp., and Zea mays), and Rosaceae (Malus domestica); and experimentally proven to also infect Brassicaceae (Brassica napus), Fabaceae (Cicer arietinum), Poaceae (Oryza sativa, Secale cereale, Sorghum sp., and Triticosecale rimpaui) (Akinsanmi et al. 2007, EFSA Panel on Plant Health et al. 2022, Farr et al. 2023). This is a globally distributed species reported from Asia (Azerbaijan, China, Iran, Malaysia, Syria, Iraq, and Türkiye), Africa (Algeria, Morocco, South Africa, and Tunisia), Europe (Italy, Netherlands, and Spain), North and South America (Argentina, Canada and USA), and Oceania (Australia, New Zealand) (EFSA Panel on Plant Health et al. 2022, Farr et al. 2023).
