双环蘑菇组（Agaricus section Duploannulus）包括与蘑菇A. bisporus和A.双托溴铵。关于这一群体的构成，文献中存在着分歧。我们使用的DNA序列数据从核核糖体DNA区域的ITS片段，在欧洲和北美的分离株的样本，以确定该组所共有的字符，进一步划定物种水平的类群内的部分，并制定一个系统发育假说。共享的多态性，建议一个自然的限制部分Duploannulopathy被发现。ITS1数据进行了评估，使用简约，距离和最大似然方法的同源性。该节Duploannulus包括六个强大的分支。5个分支对应于温带北方半球的特征种（A. bisporus、双孢A. subfloccosus，A. bitorbidae，A. vaporarius、拟野螟A.柏枝属）。第六个分支包含一个A. devoniensis复合体物种的概念，命名和关系进行了讨论，并与以前的报告进行比较。
Agaricus section Duploannulatae comprises the group of species allied with A. bisporus and A. bitorquis. Disagreement exists in the literature regarding the composition of this group. We used DNA sequence data from the ITS segments of the nuclear ribosomal DNA region, in a sample of European and North American isolates, to identify characters shared by this group, to further delimit species-level taxa within the section, and to develop a phylogenetic hypothesis. Shared polymorphisms that suggest a natural limit for section Duploannulatae were found. ITS1 data were assessed using parsimony, distance and maximum likelihood methods of phylogeny. The section Duploannulatae comprised six robust clades. Five clades corresponded to well characterized species from the temperate Northern Hemisphere (A. bisporus, A. subfloccosus, A. bitorquis, A. vaporarius, A. cupressicola). The sixth clade encompassed an A. devoniensis complex. Species concepts, nomenclature, and relationships are discussed and compared with prior reports.
