Global fungal diversity is estimated at about 6.2 million species, but only 150 000 are currently described. Molecular studies reveal that this diversity is often underestimated, especially in less-studied regions. , a genus of ramarioid fungi, has a wide distribution in areas with temperate and tropical climates. However, in southern South America, research on species has been scarce, with only a few studies conducted in Argentina covering the morphology of a few species. This research aims to analyze species in Argentina, exploring their morphology, ecological roles, and distribution. Four different ecological regions across Argentina were sampled. Molecular data (Sanger and next-generation sequencing [NGS] technology) were obtained to construct their phylogenetic relationships. Our results show a greater diversity of than previously known. Eight taxa are described here, four of which are new species to science (, and ). Additionally, a neotypification is proposed for . For the other three species (, and ), we provide new molecular data and elucidate their phylogenetic relationships with other previously described species. In addition, a key to species of from Argentina and Chile is included to facilitate identification of known taxa. Finally, most species richness is associated with tropical and subtropical forests.
全球真菌多样性估计约有620万种，但目前仅描述了15万种。分子研究表明，这种多样性常常被低估，尤其是在研究较少的地区。[某属]伞形真菌在温带和热带气候地区分布广泛。然而，在南美洲南部，对[该属]物种的研究很少，在阿根廷仅有少数研究涉及一些物种的形态。本研究旨在分析阿根廷的[该属]物种，探索它们的形态、生态作用和分布。对阿根廷四个不同的生态区域进行了采样。获取了分子数据（桑格测序和新一代测序[NGS]技术）以构建它们的系统发育关系。我们的结果显示[该属]的多样性比以前所知的更多。这里描述了八个分类单元，其中四个是科学上新发现的物种（[具体物种名1]、[具体物种名2]、[具体物种名3]和[具体物种名4]）。此外，还为[某物种]提出了新模式指定。对于其他三个物种（[具体物种名5]、[具体物种名6]和[具体物种名7]），我们提供了新的分子数据并阐明了它们与其他先前描述物种的系统发育关系。此外，还包括了阿根廷和智利[该属]物种的检索表，以方便已知分类单元的鉴定。最后，大多数[该属]物种丰富度与热带和亚热带森林相关。
