Position class (Pcl) information of cox1 gene in the 22 Agaricales species. Introns of cox1 genes of the 22 Agaricales mitogenomes were classified into different position classes (Pcls) according to the method described by Férandon et al. (2010). II represents group II introns, and UN represents novel introns never detected in previous studies. The phylogenetic positions of 22 Agaricales species were established using the Bayesian inference (BI) method and Maximum Likelihood (ML) method based on concatenated mitochondrial genes. Species information is shown in Supplementary Table S1
