ABSTRACT We are becoming increasingly aware of the dazzling diversity of fungi—new taxa are being discovered from poorly sampled habitats and integrative approaches point at (near-)cryptic species in many groups. The class Laboulbeniomycetes, which is composed of three orders (Herpomycetales, Laboulbeniales, Pyxidiophorales), is no exception. However, still, in the orders Herpomycetales and Laboulbeniales, species are predominantly described based on morphology alone. Here, we present a new species of Herpomyces from Argentina parasitic on Periplaneta fuliginosa, the smokybrown cockroach. Herpomyces spegazzinii, sp. nov., is characterized based on morphology and molecular data. Phylogenetic inference based on internal transcribed spacer (ITS, consisting of ITS1-5.8S-ITS2) barcode region supports the status of this fungus as a separate species, sister to the recently described H. shelfordellae.

阿根廷黑大蠊（Blattodea：Blattidae）上的一新种Herpomyces（Laboulbeniomycetes：Herpomycetales）

摘要我们越来越意识到真菌令人眼花缭乱的多样性——新的分类群正在从样本不足的栖息地中被发现，综合方法指向许多群体中的（近）隐匿物种。Laboulbeniomycetes 纲由三个目（Herpomycetales、Laboulbeniales、Pyxidiophorales）组成，也不例外。然而，在 Herpomycetales 和 Laboulbeniales 目中，物种主要仅根据形态学来描述。在这里，我们展示了一种来自阿根廷的 Herpomyces 新物种，它寄生在 Periplaneta fuliginosa，即烟褐色蟑螂上。Herpomyces spegazzinii, sp. 11月，根据形态学和分子数据进行表征。基于内部转录间隔区（ITS，由 ITS1-5.8S-ITS2 组成）条形码区域的系统发育推断支持这种真菌作为一个独立物种的状态，
