Figure – Phylogram generated from maximum likelihood analysis based on combined LSU, SSU and ITS sequence data of selected taxa from Koralionastetales, Lulworthiales and Pisorisporiales. Sixty-nine strains are included in the combined gene analyses comprising 2780 characters after alignment (930 characters for LSU, 1059 characters for SSU and 784 characters for ITS). Fuscosporella pyriformis (MFLUCC 16-0570) and Parafuscosporella mucosa (MFLUCC 16-0571) are used as outgroup taxa. Analyses of each single gene were performed and the topology of each tree had clade stability. The tree topology of the maximum likelihood was similar to the Bayesian and maximum parsimony analyses. Maximum likelihood analysis with 1000 bootstrap replicates yielded a best tree with the likelihood value of -24852.531353. The matrix had 1582 distinct alignment patterns, with 38.88% of undetermined characters or gaps. Estimated base frequencies were as follows; A = 0.249996, C = 0.239207, G = 0.291483, T = 0.219314; substitution rates AC = 1.016404, AG = 2.006035, AT = 1.090073, CG = 1.243791, CT = 5.331398, GT = 1.000000; gamma distribution shape parameter α = 0.395174. Maximum parsimony (black) and maximum likelihood (black) bootstrap values >65% and Bayesian posterior probabilities (green) >0.90 (ML/BYPP) are given above the nodes. Ex-type strains are in bold and new strains are in blue.
