Coccidioides posadasii sp. nov., formerly known as non-California (non-CA) Coccidioides immitis, is described. Phylogenetic analyses using single nucleotide polymorphisms, genes, and microsatellites show that C. posadasii represents a divergent, genetically recombining monophyletic clade. Coccidioides posadasii can be distinguished from C. immitis by numerous DNA polymorphisms, and we show how either of two microsatellite loci may be used as diagnostic markers for this species. Growth experiments show that C. posadasii has significantly slower growth rates on high-salt media when compared with C. immitis, suggesting that other phenotypic characters may exist.
新型 Cocci⁃dioides posadasii，以前称为非加利福尼亚（非 CA）的 Cocci⁃dioides immitis，现被描述。基于单核苷酸多态性、基因和微卫星的系统发育分析表明，C. posadasii 代表了一个分化的、具有遗传重组的单系群。C. posadasii 可以通过许多 DNA 多态性与 C. immitis 区分开来，我们展示了如何使用两个微卫星位点中的任意一个作为该物种的诊断标记。生长实验表明，与 C. immitis 相比，C. posadasii 在高盐培养基上的生长速度明显较慢，这表明可能存在其他表型特征。
