蘑菇亚属Spissicaules在世界上分布广泛。本研究对114份标本进行多基因系统发育分析，从而更好地界定了a . subg的4个区段。Spissicaules。本文描述了来自中国的三种新种：褐变a.b.、北京a.b.和平头a.b.，并将它们放在不同的章节中。无效描述的A. catenariocystidiosus在这里被证实为一个额外的新种。通过对三个近缘种A. thiersii、A. parasubrutilescens和A. linzhiensis的序列比较，支持了这三个物种之间的区别，尽管linzhiensis具有高的种内变异性和大量的异型性，这是由于其具有类群性。
Agaricus subgenus Spissicaules is widely distributed in the world. In this study, 114 specimens were included in multigene phylogenetic analyses that allowed a better circumscription of the four sections in A. subg. Spissicaules. Three new species from China, A. brunneovariabilis, A. beijingensis, and A. planiceps, are described and placed in different sections. The invalidly described A. catenariocystidiosus is validated here as an additional new species. Comparisons between the sequences of the three closely related species A. thiersii, A. parasubrutilescens, and A. linzhiensis support the distinction between these three species despite the paraphyly of A. linzhiensis, which results from its high intraspecific variability with numerous heteromorphisms.
