Notes: Fusarium mastigosporum is one of nine segregates of F. longipes recognized here (see additional notes under F. cygneum and F. longipes). Previously assigned to Fusarium longipes 1 in Laraba et al. (2021), it produces large whip-like macroconidia, common, but not exclusive to the Longipes clade of FSAMSC, and observed also in F. cygneum, F. dolichosporum, F. longicolle, F. magnum, and F. procumbens. Fusarium mastigosporum is distinguished by a combination of characters i.e., very long (av. 127.7 × 4.3 µm), robust, whip-like sporodochial conidia, and the presence of a secondary, falcate macroconidial morphotype on aerial conidiophores.
This species has been recorded on soil, other fungi (Daldinia sp.), and plant hosts in Poaceae (Sporobolus africanus and Triticim sp.), Rosaceae (Rubus sp.), and Solanaceae (Solanum tuberosum), in North America (US), Europe (Germany), and Oceania (Australia and New Zealand) (Farr et al. 2023)
