Phylogenetic tree of 79 Fusarium taxa plus FW16.1 estimated by partitioned maximum likelihood bootstrapping. Numbers at internal nodes indicate branch support based on 5000 data pseudo-replicates in IQ-TREE. The tree was rooted at NRRL 22,090 F. iludens and NRRL 22,632 F. plagianthi. The alignment holds 3209 columns and 1024 distinct patterns, of which 658 are parsimony-informative, 258 are singletons, and 293 are constant sites. FSSC numbers in brackets represent the ad hoc nomenclature previously used to distinguish species (10.1128/JCM.02371-07). T = ex-type strains; IT = ex-isotype strain; NT = ex-neotype strain
