Escovopsis是一组不同的真菌，被认为是真菌生长蚂蚁的真菌品种的专门寄生虫。缺乏合适的分类框架和系统发育的不一致性长期阻碍了Escovopsis的研究。本研究的目的是利用分类学方法和全面的多位点系统发育分析来重新评估Escovopsis属，为Escovopsis属的系统学研究奠定基础并为未来的研究奠定基础。我们的研究结果支持Escovopsis分为三个不同的属。鉴于此，我们将Escovopsis重新定义为一个单系分支，其主要特征是在分生孢子梗上形成末端囊泡。因此，E. kreiselii和E.拟绒皮菌属（Acidodermoides）重组为Sympodiorosea和Luteomyces两个新属。kreiselii和L.分别为类棘皮菌属（Aciddermoides）。这项研究扩大了我们的系统学的Escovopsis和相关属的理解，从而促进未来的研究的进化历史，分类多样性，这些居民的attine蚁群的生态作用。在线版本包含补充材料，可通过10.1186/s43008-021-00078-8获取。
Escovopsis is a diverse group of fungi, which are considered specialized parasites of the fungal cultivars of fungus-growing ants. The lack of a suitable taxonomic framework and phylogenetic inconsistencies have long hampered Escovopsis research. The aim of this study is to reassess the genus Escovopsis using a taxonomic approach and a comprehensive multilocus phylogenetic analysis, in order to set the basis of the genus systematics and the stage for future Escovopsis research. Our results support the separation of Escovopsis into three distinct genera. In light of this, we redefine Escovopsis as a monophyletic clade whose main feature is to form terminal vesicles on conidiophores. Consequently, E. kreiselii and E. trichodermoides were recombined into two new genera, Sympodiorosea and Luteomyces, as S. kreiselii and L. trichodermoides, respectively. This study expands our understanding of the systematics of Escovopsis and related genera, thereby facilitating future research on the evolutionary history, taxonomic diversity, and ecological roles of these inhabitants of the attine ant colonies.
