Phylogenies based on ITS and LSU nrDNA sequences show Agaricus (Gymnopus) acervatus as unique within the Gymnopus/Rhodocollybia complex. These phylogenies imply that a separate genus is necessary, and Connopus is proposed. Infraspecific morphological and DNA-based variation within C. acervatus suggests that a western North American clade might be reproductively isolated from the eastern North American/Scandinavian clade and that in this species complex the European and eastern North American clade might be conspecific. A Scandinavian exemplar is selected for bar-coding. Two GenBank sequences with name-phylogenetic placement inconsistencies are identified.
基于 ITS 和 LSU nrDNA 序列的系统发育分析表明，鳞伞属（Gymnopus）的锐鳞伞（Agaricus acervatus）在 Gymnopus/Rhodocollybia 复合体中是独一无二的。这些系统发育分析表明需要单独设立一个属，因此建议使用 Connopus 这个属名。锐鳞伞种内的形态和基于 DNA 的变异表明，北美西部的一个分支可能与北美东部/斯堪的纳维亚的分支在繁殖上是隔离的，并且在这个种的复合体中，欧洲和北美东部的分支可能是同一种。选择了一个斯堪的纳维亚标本进行条形码分析。确定了两个与名称-系统发育位置不一致的 GenBank 序列。
