## TL;DR

This study characterizes the complete mitochondrial genome of Fomitopsis palustris from China and analyzes its evolutionary relationships with related species.

## Contribution

The first complete mitochondrial genome of Fomitopsis palustris from China is sequenced and phylogenetically analyzed.

## Key findings

- The mitochondrial genome is 64,223 bp long with a GC content of 23.89%.
- Phylogenetic analysis shows F. palustris is closely related to F. pinicola.
- The genome includes 15 protein-coding genes, 26 tRNAs, and two rRNAs.

## Abstract

Fomitopsis palustris (Berk. & M.A. Curtis) Gilb. & Ryvarden, 1985 is a well-known brown-rot basidiomycete. However, the complete mitochondrial genome of F. palustris from China remains uncharacterized. In this study, we present the complete mitochondrial genome sequence of F. palustris, which spans 64,223 bp and has a GC content of 23.89%. The genome contains 15 essential protein-coding genes, 10 other ORFs, nine intronic ORFs, 26 tRNAs, and two rRNAs. Phylogenetic analysis via Bayesian inference (BI) was conducted to elucidate the evolutionary relationships among 10 closely related species, revealing well-supported clades and revealing the close relationship between F. palustris and F. pinicola.
