The genus has a long research history and is known for its high species diversity worldwide. However, its species diversity in China remains poorly understood. Through a combination of detailed morphological studies and phylogenetic analysis, this study described two new species from Northeast and Central China, and , both belonging to Gymnopussect.Levipedes. is characterized by basidiomata appearing in summer and originating from broad-leaved forests, a dark reddish-brown pileus, a cylindrical to clavate stipe, and clavate to cylindrical, diverticulate cheilocystidia. differs by the yellowish-white to light brown basidiomata arising from coniferous and broad-leaved mixed forests, coralloid but inflated pileipellis terminal cells, and an apex of cheilocystidia not coralloid. Additionally, a key to the reported species of Gymnopussect.Levipedes in China is provided.
该属具有悠久的研究历史，以其在全球范围内的高物种多样性而闻名。然而，其在中国的物种多样性仍知之甚少。通过详细的形态学研究和系统发育分析相结合，本研究描述了来自中国东北和中部的两个新物种，即[物种名1]和[物种名2]，它们均属于靴耳属（Gymnopussect.）的纤足靴耳组（Levipedes）。[物种名1]的特征是担子果在夏季出现，生于阔叶林，菌盖暗红褐色，菌柄圆柱形至棒状，以及菌褶囊状体棒状至圆柱形、具小瘤。[物种名2]的不同之处在于其担子果黄白色至浅褐色，生于针叶林和阔叶林混交林，菌盖表层末端细胞珊瑚状但膨大，以及菌褶囊状体顶端非珊瑚状。此外，还提供了中国已报道的纤足靴耳组（Gymnopussect.Levipedes）物种的检索表。
