Bayesian tree (GTR model, G + I distributed sites) based on a concatenated alignment of atp6, atp8, atp9, cob, cox1, cox2, cox3, nad1, nad2, nad3, nad4, nad4L, nad5, and nad6 of 43 chytrid isolates with A. macrogynus (Blastocladiomycota) serving as outgroup. Bayesian posterior probabilities are displayed at branch nodes. Highlighted in bold is the S. endobioticum mtDNA reference isolate MB42. Species with linear mtDNA genomes are indicted with an asterisk “*”
