Phylogram generated from maximum likelihood (RAxML) analysis based on RPB2 sequence data matrix for 34 Inocybe species. Sequences of Inocybe species belonging to the Pseudosperma clade used in this study have been selected from a previous analysis of Kropp et al. (2013). Values at nodes indicate bootstrap support. BS values ≥50% are shown. Inocybe luteobrunnea, I. brunneosquamulosa and I. rubrobrunnea are in pink to highlight its phylogenetic position in the tree. The tree is rooted with I. adaequata and I. calamistrata of Inosperma clade.
