The phylogeny of ancestral clade α, which predates basidiomycete–ascomycete split, contains conserved NR-PKSs biosynthesizing orsellinic acid (pks14, pks1). Support noted below branches in form BI/ML/C (BI, support from BI; ML, support from ML ultrafast bootstrap; C, whether bipartition is present in Bayesian consensus tree; * denotes full support, % denotes support below 1% level). Domain architecture and gene structure are visualized on the right side (colors: red, SAT; blue, KS; green, AT; purple, PT; orange, ACP; pink, TE; brown, R). Color of the tree edges and letters denote predicted events (D, duplication; TD, transfer donated; TA, transfer accepted). Tree is not drawn to scale.
