The complete mitochondrial genome sequences of <i>Phlebopus portentosus</i> and <i>Leccinum extremiorientale</i> (Boletales; Boletinellaceae: Phlebopus; Leccinum)

In this study, the complete mitochondrial genomes of <i>Phlebopus portentosus</i> and <i>Leccinum extremiorientale</i> were first sequencedusing the PacBio sequencing platform. We assembled circular mitogenomes of <i>P. portentosus</i> (57,307 bp) and <i>L. extremiorientale</i> (45,100 bp), with AT contents of 78.43% and 76.85%, respectively. Phylogenetic analysis revealed that <i>P. portentosus</i> and <i>L. extremiorientale</i> formed a well-supported clade with <i>Tylopilus brunneirubens</i> and <i>Suillus huapi</i> within the Boletales. This study provides high-quality reference genomes for future domestication and genetic breeding programs of <i>P. portentosus</i> and <i>L. extremiorientale.</i>
