Phylogenetic reconstruction of Endogonales based on 18S rDNA sequences. The node “D” defines the family Densosporaceae. Mortierella verticillata was used as outgroup. The tree shows the topology obtained with the Bayesian method; branches with Bayesian posterior probabilities ≥0.95 are thickened and ML bootstrap support values ≥70 are shown. Sequences generated in this study are in bold.
