Phylogenetic trees resulting from three analytical methods of the 3-gene DNA sequence dataset assembled for this manuscript. Only the Ardissoneaceae and their sister group in the molecular phylogeny, Lampriscus, is shown here—the complete trees can be found in Suppl. materials 5–7: Figs S3–S5 A Maximum Likelihood phylogeny resolved by RAxML, where values at nodes are bootstrap support values B Maximum Likelihood phylogeny resolved by IQTREE, where values at nodes are bootstrap support values C Bayesian Inference phylogeny resolved by ExaBayes, where values at nodes are posterior probability values. Strain taxonomy (name followed by DNA voucher ID or strain ID) follows currently accepted classification, with proposed genera based on morphology shown to the right of strain ID.
