Position class (Pcl) information of cox1 genes in the 6 Phallomycetidae species. Introns in cox1 genes of the 6 Phallomycetidae mitogenomes were classified into different position classes (Pcls) using the cox1 gene of Ganoderma calidophilum as the reference. Each Pcl was constituted by introns inserted at the same position of corresponding cox1 gene and named according to its insertion site in the aligned corresponding reference sequence (nt). Phylogenetic positions of the 6 Phallomycetidae species were established using the Bayesian inference (BI) method and Maximum Likelihood (ML) method based on concatenated mitochondrial genes
