Abstract
Auricularia delicata (Mont.) Henn. 1893 is an edible and medicinal jelly mushroom popular in China. Here, we report the assembly and annotation of a complete A. delicata mitochondrial genome based on data sequenced using an Illumina NovaSeq 6000 platform. The length of the complete circular A. delicata mitochondrial genome is 189,696 bp, with a GC content of 34.1%. The A. delicata mitochondrial genome contains 60 genes, including 32 protein-coding genes, 26 tRNA genes, and two rRNA genes. Phylogenetic analysis indicated that A. delicata clustered with the Auricularia group, alongside A. auricula-judae and A. heimuer. Additionally, A. delicata was found to be genetically distant from other species of Polyporales, Russulales, and Agaricales. This genome will provide an invaluable reference for the continued study and utilization of A. delicata and other Auricularia species.
