(Agaricales, Omphalotaceae) is a saprobic mushroom-forming genus characterized by gymnopoid, omphaloid, and pleurotoid basidiome, and ellipsoid to cylindrical basidiospores. Currently, 66 species are classified as the genus through continuous taxonomic validations to resolve taxonomic confusions caused by morphological similarities with other genera, such as and . In Korea, 16 species have been recently identified, but there are still many undiscovered species. In this study, four specimens were collected from Mudeungsan National Park in July from 2021 to 2022. They were identified as two new species through morphological, molecular, and multi-marker phylogenetic analyses based on nuclear ribosomal internal transcribed spacer (ITS) and nuclear large subunit ribosomal DNA (nLSU) regions. Detailed morphological descriptions and a phylogenetic tree are provided to suggest these species as sp. nov. and sp. nov.
（伞菌目，红菇科）是一个形成腐生蘑菇的属，其特征为裸盖型、脐菇型和侧耳型担子果，以及椭圆形至圆柱形的担孢子。目前，通过持续的分类学验证，已有66个物种被归入该属，以解决因与其他属（如[此处原文缺失相关属名]和[此处原文缺失相关属名]）形态相似而导致的分类学混淆问题。在韩国，最近已鉴定出16个物种，但仍有许多未被发现的物种。在本研究中，于2021年至2022年7月从母岳山国家公园采集了4个[此处原文缺失相关物种名称]标本。通过基于核糖体内部转录间隔区（ITS）和核糖体DNA大亚基（nLSU）区域的形态学、分子学和多标记系统发育分析，将它们鉴定为两个新物种。提供了详细的形态描述和系统发育树，以将这些物种分别命名为[此处原文缺失新物种名1]新种和[此处原文缺失新物种名2]新种。
