This Appendix dataset accompanies a review of Fusarium genomes and their respective host ranges, entitled 'Navigating the Fusarium species complex: Host-Range Plasticity and Genome Variations', published in Fungal Biology (https://doi.org/10.1016/j.funbio.2024.07.004). The information within this dataset was correct as of March 2024 and includes information on Species, NCBI identifier, Assigned Phylogenetic Clade, The number of genomes available on NCBI, Ungapped Genome Size, Number of Chromosomes, Number of Core and Lineage Specific (LS) Chromosomes (by karyotyping), the Sequencing Methodology and Source. It also includes an extensive, but not universal, curation of known host ranges for each species. It is our hope that by making this dataset freely available it will encourage and inspire further research into the Fusarium genus.
