Seventeen Unrecorded Species from Gayasan National Park in Korea

Macrofungi play important roles in forest ecology as wood decayers, symbionts, and pathogens of living trees. For the effective forest management, it is imperative to have a comprehensive overview of macrofungi diversity in specific areas. As a part of the National Institute of Biological Resources projects for discovering indigenous fungi in Korea, we collected macrofungi in Gayasan National Park from 2017 to 2018. These specimens were identified based on morphological characteristics and sequence analysis of internal transcribed spacer (ITS) or the nuclear large subunit rRNA (LSU) region. We discovered 17 macrofungi new to Korea: Butyrea japonica, Ceriporia nanlingensis, Coltricia weii, Coltriciella subglobosa, Crepidotus crocophyllus, Cylindrobasidium laeve, Fulvoderma scaurum, Laetiporus cremeiporus, Lentinellus castoreus, Leucogyrophana mollusca, Marasmius insolitus, Nidularia deformis, Phaeophlebiopsis peniophoroides, Phanerochaete angustocystidiata, Phlebiopsis pilatii, Postia coeruleivirens, and Tengioboletus fujianensis. We described their detailed morphological characteristics.

大型真菌（Macrofungi）作为木材分解者、菌根共生体与活树病原菌，在森林生态系统中发挥着关键生态功能。为实现科学高效的森林经营管理，全面掌握特定区域内大型真菌的多样性分布格局至关重要。作为韩国生物资源研究院（National Institute of Biological Resources）本土真菌发掘项目的子任务，研究团队于2017至2018年间在鸡龙山国家公园（Gayasan National Park）开展了大型真菌样本采集工作。所有标本均通过形态学特征观察，以及内部转录间隔区（Internal Transcribed Spacer, ITS）或核核糖体大亚基rRNA（Nuclear Large Subunit rRNA, LSU）区域的序列分析完成物种鉴定。本次研究共发现17种韩国新记录大型真菌：Butyrea japonica、Ceriporia nanlingensis、Coltricia weii、Coltriciella subglobosa、Crepidotus crocophyllus、Cylindrobasidium laeve、Fulvoderma scaurum、Laetiporus cremeiporus、Lentinellus castoreus、Leucogyrophana mollusca、Marasmius insolitus、Nidularia deformis、Phaeophlebiopsis peniophoroides、Phanerochaete angustocystidiata、Phlebiopsis pilatii、Postia coeruleivirens及Tengioboletus fujianensis。研究团队对上述新记录物种的形态学特征进行了详尽描述。
