Phylogeny and comparative analysis of mitochondrial genomes of <i>Gomphus</i> spp. Pers. (Basidiomycota, Agaricomycetes), with descriptions of <i>G. matijun</i> J.W. Liu & F.Q. Yu and <i>G. bijiensis</i> sp. nov.

ABSTRACT: The genus Gomphus Pers. presents persistent taxonomic challenges due to its morphological similarities with related genera. In this study, we collected two specimens of Gomphus from Guizhou, China; one specimen is described as a new species, Gomphus bijiensis sp. nov. and the other is identified as G. matijun J.W. Liu & F.Q. Yu based on morphological traits and phylogenetic analyses of the nuclear rDNA internal transcribed spacer (ITS) and nuclear rDNA large subunit (LSU). To resolve their evolutionary relationships we assembled and annotated the mitochondrial genomes of both species using next-generation sequencing. Comparative analyses revealed codon usage strongly biased toward A- or U-ending codons, consistent with the low GC content typical of fungal
