Proportion of increased or decreased support values for 100 backbone, genus group, genus, species group, and species nodes of the 705-OTU Physciaceae dataset analysed under maximum likelihood with ambiguous regions either excluded or recoded with PICS-Ord. Nodes were divided according to whether PICS-Ord recoding performed better than, identical to, or worse than excluding ambiguous regions. Numbers in parentheses indicate mean difference in support values using PICS-Ord versus the other two methods.
