Bayesian inference of phylogenetic relationships between the sampled Microbotryum species: Markov chain Monte Carlo analysis of an alignment of concatenated ITS + LSU base sequences using the GTR+I+G model of DNA substitution with gamma distributed substitution rates and estimation of invariant sites, random starting trees, and default starting parameters of the DNA substitution model. A 50% majority-rule consensus tree is shown computed from 75 000 trees that were sampled after the process had reached stationarity. The topology was rooted with Microbotryum scabiosae. Numbers on branches before slashes are estimates for a posteriori probabilities; numbers on branches after slashes are ML bootstrap support values. Branch lengths were averaged over the sampled trees. They are scaled in terms of expected numbers of nucleotide substitutions per site. The colour dots refer to ITS genotypes of Microbotryum silenes-acaulis (see also Fig. 5). D. = Dianthus, M. = Microbotryum, S. = Silene.
