In this study, the complete mitogenome of an entomopathogenic fungus Orbiocrella petchii (syn. Torrubiella petchii) was assembled and annotated. This circular mitogenome was 23,794 bp in length and consisted of 2 rRNA genes (rnl and rns), 25 tRNA genes, and 14 standard protein-coding genes of the oxidative phosphorylation system. Two group I introns were identified, and they encoded ribosomal protein S3 (in rnl) or a GIY-YIG endonuclease (in nad1). Phylogenetic analysis based on mitochondrial DNA sequences confirms O. petchii in the family of Clavicipitaceae.
