本文对北美西部的华贵羊肚菌复合体进行了系统发育和分类研究。我们的分析表明，北美西部和欧洲标本参照I.plendens Sensu Lato聚为八个分支，并且该分类群的欧洲和北美西部的代表不是同种的。Splendentes组和Inocybe的超组“Margiatae”，光滑孢子分类群的特征是一种独特的发育特征的综合征(完全或大部分具粉状柄，没有Cortina，经常存在边缘状的基鳞茎)，不是单系。文中讨论了I.plendens的种概念，并指定了I.s plendens Sensu Heim的一个选型。记述了两个新种：I.monticola和I.preecox。从模式材料中重新描述了鲜为人知的种I.bakeri，并提供了22种的检索表，用于鉴定这些种和其他非发红的种，具有光滑的孢子和来自北美和欧洲的具茎囊状的柄。
A phylogenetic and taxonomic study of the Inocybe splendens complex in western North America is presented. Our analysis indicates that western North American and European specimens referable to I. splendens sensu lato cluster into eight clades and that European and western North American representatives of this taxon are not conspecific. Section Splendentes and supersection "Marginatae" of Inocybe, smooth-spored taxa characterized by a syndrome of unique developmental characters (entirely or mostly pruinose stipe, absence of cortina, frequent presence of marginate basal bulb) are not monophyletic. The species concept for I. splendens is discussed, and a lectotype for I. splendens sensu Heim is designated. Two new species, I. monticola and I. praecox, are illustrated and described. The poorly known species I. bakeri is redescribed from type material, and a key for 22 species is provided for identification of these and other non-reddening species with smooth spores and a caulocystidiate stipe reported from North America and Europe.
