Cunninghamella, a filamentous fungal genus with important biomedical and biochemical value, lacks any fully annotated mitochondrial genome to date. Herein, we presented the first complete mitogenome of Cunninghamella elegans, a circular 41,552 bp molecule (GC 27.86%) encoding 14 conserved protein-coding genes, 2 rRNA genes, 24 tRNA genes, and 6 non-conserved ORFs. Structural comparison with related species (Absidia glauca and Gongronella sp. w5) revealed dynamic evolution in intron and repeat elements. Phylogenetics places C. elegans within Cunninghamellaceae, with Gongronella as its closest relative. This reference mitogenome will underpin future evolutionary and taxonomic investigations of this industrially and medically significant lineage.
