Ceratocystiopsis is a fungal genus that has been assigned to the Ophiostomatales, fungi known for their association with various bark beetles and other arthropods. The mitochondrial genome of Ceratocystiopsis pallidobrunnea has been characterized and compared with other members of the genus Ceratocystiopsis and Ophiostomatales. At 29 022 bp, the mitogenome of C. pallidobrunnea is the smallest reported so far for this genus. Gene arrangement was observed to be conserved for this group of fungi, and mitogenome variation appears to be mostly due to the absence and presence of introns. The long-term goal is to apply mitogenomes to resolve taxonomic issues within the Ophiostomatales and within the various genera that comprise the Ophiostomataceae.
