During an investigation of the macrofungal flora in the Huanglong Mountains of the Loess Plateau, northwest China, a unique gomphoid fungus was discovered and collected. After morphological identification and molecular phylogenetic analyses, a new genus named and its type species, , were proposed. Phylogenetic analyses were conducted using datasets of nuclear ribosomal DNA 28S large subunit (LSU), mitochondrial (mt) adenosine triphosphatase (ATPase) subunit 6 (atp6), and mt small-subunit rDNA (mtSSU). The results confirmed that forms an independent clade within Gomphales, with full maximum likelihood bootstrap support (MLBS), maximum parsimony bootstrap support (MPBS), and Bayesian posterior probability (BPP). is characterized by its sandy-brown, orange-brown, or coffee-brown color; clavate to infundibuliform shape; wrinkled and ridged hymenophore; ellipsoid to obovoid warted basidiospores; cylindrical to clavate flexuous pleurocystidia; and crystal basal mycelium. Overall, this study contributes to the growing body of knowledge on the diversity and evolution of Gomphales and provides valuable insights into the unique fungal flora found in the Huanglong Mountains.
在中国西北部黄土高原黄龙山脉大型真菌区系的调查过程中，发现并采集到一种独特的 gomphoid 真菌。经过形态学鉴定和分子系统发育分析，提出了一个新属及其模式种。使用核糖体 DNA 28S 大亚基（LSU）、线粒体（mt）腺苷三磷酸酶（ATPase）亚基 6（atp6）和 mt 小亚基 rDNA（mtSSU）数据集进行系统发育分析。结果证实，该真菌在 Gomphales 目内形成一个独立分支，具有完全的最大似然法自展支持率（MLBS）、最大简约法自展支持率（MPBS）和贝叶斯后验概率（BPP）。该真菌的特征在于其沙褐色、橙褐色或咖啡褐色；棒状至漏斗状的形状；具皱纹和棱纹的子实层体；椭圆形至倒卵形具疣的担孢子；圆柱形至棒状弯曲的侧生囊状体；以及具晶体的基部菌丝体。总体而言，本研究有助于增加关于 Gomphales 目多样性和进化的知识体系，并为黄龙山脉发现的独特真菌区系提供了有价值的见解。
