Abstract

Collybiopsis (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 Collybiopsis through continuous taxonomic validations to resolve taxonomic confusions caused by morphological similarities with other genera, such as Marasmiellus and Gymnopus. In Korea, 16 Collybiopsis species have been recently identified, but there are still many undiscovered species. In this study, four Collybiopsis 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 C. albida sp. nov. and C. pini sp. nov.

标题无登山国立公园大腹虫属二新种（鞘翅目，鞘翅目）。

伞生菌属（蘑菇科，伞生菌科）是一种腐生菌属，以裸子孢子、伞生孢子和胸膜孢子和椭球到圆柱形的担子孢子为特征。目前，通过不断的分类验证，66种被归为Collybiopsis属，以解决与其他属（如Marasmiellus和Gymnopus）因形态相似而造成的分类混淆。在国内，虽然最近发现了16种Collybiopsis，但仍有许多未被发现的物种。本次研究于2021年~ 2022年7月在无登山国立公园采集了4件大肠标本。通过核糖体内部转录间隔区（ITS）和核糖体大亚基DNA （nLSU）区域的形态、分子和多标记系统发育分析，鉴定为两个新种。详细的形态描述和系统发育树表明这两个物种分别是C. albida sp. nov和C. pini sp. nov。

期刊介绍： Mycobiology is an international journal devoted to the publication of fundamental and applied investigations on all aspects of mycology and their traditional allies. It is published quarterly and is the official publication of the Korean Society of Mycology. Mycobiology publishes reports of basic research on fungi and fungus-like organisms, including yeasts, filamentous fungi, lichen fungi, oomycetes, moulds, and mushroom. Topics also include molecular and cellular biology, biochemistry, metabolism, developmental biology, environmental mycology, evolution, ecology, taxonomy and systematics, genetics/genomics, fungal pathogen and disease control, physiology, and industrial biotechnology using fungi.
