Position class (Pcl) information of cox1 genes of 61 Basidiomycota species. The same Pcl (orthologous intron) is represented by the same letter. The phylogenetic positions of the species were established using the Bayesian inference (BI) method and Maximum Likelihood (ML) method based on 15 concatenated mitochondrial core proteins and 2 rRNA genes. N1 - N5 represent the newly detected Pcl in this study; The II in the figure shows the intron belongs to the group II intron. Species ID are shown in Supplementary Table S6
