Species-level global similarity scores as predicted by DNAbarcoder58 using unique fungal sequences in UNITE + INSD67 v10.0. The analysis covered three major fungal groups: Dikarya (phyla Ascomycota, Basidiomycota and Entorrhizomycota); terrestrial early diverging fungi (phyla Basidiobolomycota, Calcarisporiellomycota, Entomophthoromycota, Glomeromycota, Kickxellomycota, Mortierellomycota, Mucoromycota and Zoopagomycota); and single-celled zoosporic fungi (phyla Aphelidiomycota, Blastocladiomycota, Chytridiomycota, Monoblepharomycota, Neocallimastigomycota, Olpidiomycota, Rozellomycota and Sanchytriomycota, as well as GS01). Global similarity scores for each group are shown in parentheses. These results demonstrate that kingdom-level fungal scores are skewed toward Dikarya, and more accurate global scores of early diverging fungi can be achieved by analysing these groups separately.
