Members of -complex or olive waxcaps have both ecological and economic significance. European and North American species diversity of this fungal group has been presented in recent molecular phylogenetic studies, but no Chinese materials were included. In this study, a phylogenetic overview of the -complex based on internal transcribed spacer (ITS) sequences was made, and a local popular edible species from southwestern China was described as a new species . This new species is characterized by grayish brown, olive brown to dark brown pileus disc, inflexed to deflexed pileus margin, obvious and dark brown annulus, basidiospores measuring (8.0-)8.5-11.0(-12.0) × 5.0-7.5(-8.0) μm, and the distribution in subalpine forests dominated by and/or in southwestern China.
蜡伞属或橄榄蜡伞的成员具有生态和经济意义。近期的分子系统发育研究呈现了该真菌类群在欧洲和北美的物种多样性，但未纳入中国的材料。在本研究中，基于内转录间隔区（ITS）序列对蜡伞属进行了系统发育概述，并将中国西南部一种当地常见的可食用物种描述为一个新物种。该新物种的特征为菌盖圆盘呈灰棕色、橄榄棕色至深棕色，菌盖边缘内卷至下弯，有明显的深棕色菌环，担孢子大小为(8.0-)8.5 - 11.0(-12.0)×5.0 - 7.5(-8.0)μm，分布于中国西南部以高山松和/或云杉为主的亚高山森林中。
