The straw-rotting edible fungus is a widely cultivated edible fungus across China and Southeast Asian countries. Three complete mitochondrial genomes of from China, Thailand, and India were determined using the next-generation sequencing technology. The genome sizes of the three strains (China, Thailand, and India) were 62,541 bp, 64,531 bp, and 65,668 bp with GC contents of 38.46%, 38.56%, and 38.52%, respectively. All the genomes encoded 14 conserved protein-coding genes, the small ribosomal RNA subunits (rns), large ribosomal RNA subunits (rnl), and 23 tRNAs were located on the same strand. In the putative protein-coding genes, four introns were distributed in cox1 in the genomes of V23-1 and V8. 5 introns (four introns invaded into cox1and one intron invaded into cob) were detected in Tai8. The phylogenetic analysis confirmed that was a number of Agaricales. This mitochondrial genome may open new avenues for understanding the phylogeny and evolution of Pluteaceae and Agaricales.
草腐食用菌是一种在中国和东南亚国家广泛栽培的食用菌。利用下一代测序技术测定了来自中国、泰国和印度的三个完整线粒体基因组。这三个菌株（中国、泰国和印度）的基因组大小分别为62,541 bp、64,531 bp和65,668 bp，GC含量分别为38.46%、38.56%和38.52%。所有基因组都编码14个保守的蛋白质编码基因，小核糖体RNA亚基（rns）、大核糖体RNA亚基（rnl）和23个tRNA位于同一条链上。在假定的蛋白质编码基因中，四个内含子分布在V23-1和V8基因组的cox1中。在Tai8中检测到5个内含子（四个内含子侵入cox1，一个内含子侵入cob）。系统发育分析证实是伞菌目的一些种类。该线粒体基因组可能为理解光柄菇科和伞菌目的系统发育和进化开辟新途径。
