Two new species of sect. Trachyspermi isolated from soil are proposed, namely, T. albidus (ex-type AS3.26143) and T. rubidus (ex-type AS3.26142), based on the integrated taxonomic methods. Morphologically, T. albidus is characterized by slow growth, white gymnothecia, singly-borne asci and ellipsoidal echinulate ascospores. Talaromyces rubidus is distinguished by restricted growth, moderate to abundant red soluble pigment on CYA and YES, biverticillate penicilli, and commonly ovoid to globose echinulate conidia. The two proposed novelties are further confirmed by the phylogenetic analyses of the concatenated BenA-CaM-Rpb2-ITS sequence matrix and the individual BenA, CaM, Rpb2 and ITS sequence matrices. Talaromyces albidus is closely related to T. assiutensis and T. trachyspermus, while T. rubidus is in the clade containing T. albobiverticillius, T. rubrifaciens, T. catalonicus, T. heiheensis, T. erythromellis, T. halophytorum, T. pernambucoensis, T. solicola and T. aerius.
基于综合分类学方法，提出了从土壤中分离出的曲霉属粗糙孢子组的两个新物种，即白色曲霉（模式菌株AS3.26143）和红色曲霉（模式菌株AS3.26142）。在形态学上，白色曲霉的特征是生长缓慢、白色闭囊壳、单个着生的子囊和椭圆形具刺的子囊孢子。红色曲霉的特征是生长受限、在CYA和YES培养基上产生中度至丰富的红色可溶性色素、双轮生帚状枝以及通常为卵形至球形具刺的分生孢子。通过串联的BenA-CaM-Rpb2-ITS序列矩阵以及单独的BenA、CaM、Rpb2和ITS序列矩阵的系统发育分析，进一步证实了这两个新物种。白色曲霉与阿苏特曲霉和粗糙曲霉密切相关，而红色曲霉则位于包含白双轮曲霉、变红曲霉、加泰罗尼亚曲霉、黑河曲霉、红变赤霉、嗜盐曲霉、伯南布哥曲霉、土壤曲霉和气生曲霉的分支中。
