PhyML tree based on ribosomal ITS sequences. Bootstrap values based on 100 bootstrap replicates are at the left of the supported node. Analysis assumed the GTR model of evolution with the transition/transversion ratio, number of invariable sites and shape of the gamma distribution estimated. The log likelihood of the tree was -1776.7. Bold type = holotype of Gymnopus confluens subsp. campanulatus. Percent identity was based on the entire ITS1-5.8S-ITS2 sequence.
