Phylogenetic tree (50% majority-rule consensus) based on Bayesian Inference (MrBayes 3.1.2) of Haplosporidia based on the small subunit ribosomal gene. Numbers at the nodes are Bayesian posterior probabilities. Cercomonas longicauda, Perkinsus chesapeaki, and P. marinus were used as an outgroup for Haplosporidia based on the results of Reece et al.[9].
