, an ectomycorrhizal fungus, has long been used in traditional Chinese medicine and mushroom dyes; however, its mitogenome and phylogenetic relationship with other taxa remain unexplored. Here, we sequenced the mitochondrial genome of using next-generation sequencing and found that its mitogenome, a circular DNA molecule of 43,528 bp, comprised 15 protein-coding genes, 15 transfer RNA genes, and two ribosomal RNA genes. The mitogenome had a base composition of A (37.52%), C (11.14%), G (12.21%), and T (39.13%) and a GC content of 23.35%. A phylogenetic tree was constructed to determine the phylogenetic relationship of this species with other taxa based on the mitochondrial genome sequence. This study revealed the phylogenetic positions of and its related genera for the first time.
一种外生菌根真菌，长期以来一直用于传统中药和蘑菇染料；然而，其线粒体基因组以及与其他分类群的系统发育关系仍未得到探索。在这里，我们使用下一代测序技术对该菌的线粒体基因组进行了测序，发现其线粒体基因组是一个43528 bp的环状DNA分子，包含15个蛋白质编码基因、15个转运RNA基因和两个核糖体RNA基因。该线粒体基因组的碱基组成为A（37.52%）、C（11.14%）、G（12.21%）和T（39.13%），GC含量为23.35%。基于线粒体基因组序列构建了系统发育树，以确定该物种与其他分类群的系统发育关系。这项研究首次揭示了该菌及其相关属的系统发育位置。
