基于接合孢子的有性繁殖、孢子囊的频繁无性繁殖、缺乏多细胞子实体和产生共核菌丝，接合菌纲真菌被分类为单一门，接合菌门，所有这些都存在一些例外。然而，基于一个或几个基因的分子系统发育并不支持该门的单系性，该门随后被放弃。在这里，我们对 46 个分类单元的基因组规模数据集进行了系统发育分析，包括 25 个接合菌和 192 个蛋白质，并且我们证明接合菌包含两个形成并系等级的主要分支。本文提出了正式的系统发育分类，包括两个门、六个亚门、四个纲和 16 个目。根据这些结果，确定了毛霉菌门和动物霉菌门。 Zoopagomycota包括Entomophtoromycotina、Kickxellomycotina和Zoopagomycotina；它构成了接合菌的最早分化谱系，并且包含主要是小动物（例如阿米巴原虫、昆虫等）和其他真菌（即真菌寄生虫）的寄生虫和病原体的物种。毛霉菌门包括球囊菌亚门、被孢霉亚门和毛霉菌门，是 Dikarya 的姐妹门。它是接合菌的更衍生的进化枝，主要由菌根真菌、根内生菌和植物材料的分解者组成。讨论了营养模式、形态的进化和基因组规模数据的分析。
Zygomycete fungi were classified as a single phylum, Zygomycota, based on sexual reproduction by zygospores, frequent asexual reproduction by sporangia, absence of multicellular sporocarps, and production of coenocytic hyphae, all with some exceptions. Molecular phylogenies based on one or a few genes did not support the monophyly of the phylum, however, and the phylum was subsequently abandoned. Here we present phylogenetic analyses of a genome-scale data set for 46 taxa, including 25 zygomycetes and 192 proteins, and we demonstrate that zygomycetes comprise two major clades that form a paraphyletic grade. A formal phylogenetic classification is proposed herein and includes two phyla, six subphyla, four classes and 16 orders. On the basis of these results, the phyla Mucoromycota and Zoopagomycota are circumscribed. Zoopagomycota comprises Entomophtoromycotina, Kickxellomycotina and Zoopagomycotina; it constitutes the earliest diverging lineage of zygomycetes and contains species that are primarily parasites and pathogens of small animals (e.g. amoeba, insects, etc.) and other fungi, i.e. mycoparasites. Mucoromycota comprises Glomeromycotina, Mortierellomycotina, and Mucoromycotina and is sister to Dikarya. It is the more derived clade of zygomycetes and mainly consists of mycorrhizal fungi, root endophytes, and decomposers of plant material. Evolution of trophic modes, morphology, and analysis of genome-scale data are discussed.
