Genus Hamigera was erected for Talaro-myces species that make asci singly instead of in chains. Initially it contained two species, H. avellanea and H. striata. We describe six new species in the genus, H. fusca, H. inflata, H. insecticola, H. pallida, H. paravellanea and H. terricola. Merimbla ingelheimensis is a distinct anamorphic species in the Hamigera clade. None of our DNA sequence data (BT2, calmodulin, ITS, 1su rDNA, RPB2, Tsr1 and Mcm7) supported the placement of H. striata in the same clade as H. avellanea, thus we accepted Talaromyces striatus. In addition to Hamigera species we examined the phylogenetic disposition of Warcupiella spinulosa, Penicillium megasporum, Penicillium arenicola and Merimbla humicoloides. Despite nominal similarity of some of these species to Merimbla, none of these species are part of the Hamigera clade and M. humicoloides is placed in Penicillium to have a monophyletic genus Hamigera.
Hamigera 属是为那些产单生而非链状子囊果的 Talaro-myces 种而设立的。最初它包含两个种，H. avellanea 和 H. striata。我们在该属中描述了六个新种，即 H. fusca、H. inflata、H. insecticola、H. pallida、H. paravellanea 和 H. terricola。Merimbla ingelheimensis 是 Hamigera 分支中的一个独特的无性型种。我们的任何 DNA 序列数据（BT2、钙调蛋白、ITS、1su rDNA、RPB2、Tsr1 和 Mcm7）都不支持 H. striata 与 H. avellanea 同属于一个分支，因此我们接受 Talaromyces striatus。除了 Hamigera 种，我们还研究了 Warcupiella spinulosa、Penicillium megasporum、Penicillium arenicola 和 Merimbla humicoloides 的系统发育位置。尽管这些种中的一些在名义上与 Merimbla 相似，但它们都不属于 Hamigera 分支，而 M. humicoloides 被归入 Penicillium 以形成单系的 Hamigera 属。
