波氏球孢子菌，以前称为非加利福尼亚（non-CA）粗球孢子菌。利用单核苷酸多态性、基因和微卫星的系统发育分析表明，C。posadasii代表一个分歧的，遗传重组的单系分支。Posadasii球孢子菌与C. immitis的许多DNA多态性，我们展示了如何两个微卫星位点可作为诊断标记，这一物种。生长实验表明，C. posadasii与C. immitis，表明可能存在其他表型性状。
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.
