Abstract
Abstract Lenzites betulinus is a medicinal fungus in the Polyporaceae. Here, we report the first complete mitochondrial sequencing of this species. The circular genome is 61,288 bp in length, with a GC content of 26.32% and base composition of A (36.98%), T (36.70%), G (12.96%), and C (13.36%). It contains 14 core protein-coding genes (PCGs), 26 tRNA genes, two rRNA genes, and nine intronic ORFs within the cox1 gene. A maximum-likelihood phylogenetic tree based on 14 PCGs from 17 mitochondrial genomes confirmed that L. betulinus clusters within the Polyporaceae, closely related to Trametes and Fomitopsis. This served as a significant reference for ongoing research into other species within the Polyporales order.
