The complete mitochondrial genome of Fusicolla acetilerea (Nectriaceae, Hypocreales).

Fusicolla acetilerea (Nectriaceae, Ascomycota) is an emerging saprotrophic/plant-associated fungus whose genomic resources remain scarce. Here, we report the complete mitochondrial genome of F. acetilerea strain NIBRFGC000505922, assembled from Illumina NovaSeq reads. The circular-mapping mitogenome is 29,182 bp in length with a GC content of 28.7%. It encodes the canonical set of oxidative phosphorylation genes, two rRNA genes, 25 tRNA genes, and an intronic rps3 gene. A phylogenetic analysis based on 14 core protein-coding genes places F. acetilerea within Nectriaceae, forming a well-supported clade with Nectria cinnabarina. This mitogenome provides a reference for various genetic studies in Fusicolla and related taxa.
