Phylogenetic relationship of Trechisporales and Sistotremastrales based on Maximum Likelihood analysis of 28S nc rDNA sequences. Best-scoring tree with SH-aLRT/UFBoot2 support values above the branches is shown. Tips of the tree are annotated according to the generic affiliation of the taxa. Two members of the order Auriculariales (Exidiopsis calcea and Auricularia sp.) and two of Hymenochaetales (Litschauerella gladiola and Kneiffiella floccosa) were used as an outgroup and were marked up with a single colour for the sake of simplicity.
