FIG. 5.

Phylogenetic relationship between the 18S small-subunit rRNA of 18 mesomycetozoeans, one coralochytrean, and two choanoflagellates previously studied by Mendoza et al. (25). Multiple hit correction and 1,000 bootstrap-resampled data sets were used to assess branch support. The genus Rhinosporidium (R. canis from a dog and R. seeberi from humans) and Dermocystidium spp. from fish are both in two different well-supported groups. In this tree, Amphibiocystidium ranae is the sister group to D. fennicum and D. salmonis. In turn, both sister groups are linked to R. seeberi. The numbers above the branches are percentages of bootstrap-resampled data sets as obtained by neighbor joining. Corallochytrium limacisporum, Acanthocoepsis unguilata, and Diaphanoeca grandis were used as the outgroup. The scale bar represents evolutionary distance in substitutions per nucleotide.
