Tinctoporellus epimiltinus is widely known as a wood-decaying fungus. In the present study, we identified the complete mitochondrial genome of this species using next-generation sequencing technology. Our findings revealed that the genomic structure is a circular molecule with a size of 51,878 bp. Consistent with most Basidiomycota species, it consists of 14 core protein-coding genes, one ribosomal protein gene ( rps3 ), 26 transfer RNA genes, and small and large ribosomal RNA ( rns and rnl ) genes. Seven additional open reading frames were identified. These included two sequences similar to DNA polymerases, an endonuclease-like sequence, and four hypothetical proteins. The mitochondrial genome exhibited a nucleotide composition of A (36.24%), C (12.04%), G (13.18%), and T (38.55%), resulting in a 25.21% GC content. A phylogenetic tree constructed using the combined mitochondrial gene dataset provided insight into the phylogenetic relationships of this species within the context of Basidiomycota and its members.
