Abstract

Helvella, commonly known as saddle fungi, is a genus in the Helvellaceae family and is distributed globally. Recent comprehensive studies on Helvella have revealed that some Helvella species exhibit endemic traits and that many morphologically similar, cryptic species are phylogenetically distant. In this study, 202 Korean Helvella specimens collected between 1986 and 2023 were reevaluated through morphological analysis and phylogenetic characterization using barcode sequences, including nrLSU (nuclear Large Subunit Ribosomal DNA), hsp90 (Heat Shock Protein 90), and ITS (Internal Transcribed Spacer). The investigation confirmed the presence of at least 35 phylogenetic species in Korea. Among these, eight species (H. atroides, H. fistulosa, H. liquii, H. lobata, H. rugosa, H. subglabroides, H. sublactea, H. varia) were identified as previously unrecorded species in Korea, and seven new species (H. densipila, H. flavopus, H. macrospora, H. griseobrunnea, H. pseudolobata, H. parviflava, H. suborentitomentosa) were discovered. Of the 13 previously recorded Korean Helvella species, only three (H. ephippioides, H. macropus, H. orienticripsa) were confirmed, while the remaining ten species (H. acetabulum, H. atra, H. compressa, H. costifera, H. crispa, H. elastica, H. sublicia, H. fibrosa, H. lacunosa, H. pezizoides) were not detected in the samples studied. This study enhances our understanding of the distribution of Helvella species of Korea, revealing significant discrepancies between historical records and current findings. The discovery of new species and previously un-recorded species underscores the importance of continuous monitoring and reevaluation of fungal biodiversity.

标题韩国鞍形真菌的分类修订(Helvella, helvellacae)。
Helvella,俗称马鞍真菌,是helvellacae科的一个属,分布在全球。最近对Helvella的综合研究表明,一些Helvella物种表现出特有的特征,许多形态相似的隐种在系统发育上是遥远的。在这项研究中,通过形态学分析和系统发育特征的条形码序列,包括nrLSU(核大亚基核糖体DNA), hsp90(热休克蛋白90)和ITS(内部转录间隔),对1986年至2023年间收集的202个韩国Helvella标本进行了重新评估。此次调查确认,在韩国至少存在35种系统发育物种。其中8种(atroides、H. fistulosa、H. liquii、H. lobata、H. rugosa、H. subglabroides、H. subblactea、H. varia)为国内未记录种,7种新种(H. densipila、H. flavopus、H. macrospora、H. griseobrunnea、H. pseudolobata、H. parviflava、H. subborentitomtosa)为新发现种。在已有记录的13种韩国Helvella中,仅有3种(H. ephippioides、H. macropus、H. orienticripsa)得到确认,其余10种(H. acetabulum、H. atra、H. compressa、H. costifera、H. crispa、H. elastica、H. sublicia、H. fibrosa、H. lacunosa、H. pezizoides)未被发现。本研究揭示了历史记录与现有发现之间的重大差异,增强了我们对韩国Helvella种分布的认识。新物种和以前未记录的物种的发现强调了持续监测和重新评估真菌生物多样性的重要性。

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.
