摘要

Hymenochaetales Oberw.是真菌纲中的一个目,该目中的物种具有显著的多样性。它们的子实体形状各异,包括棍棒状、流出反折状和复羽状基生体。金门伞菌目中很少有菌根物种的报道,但木材腐烂物种在该目中占主导地位。Imazeki & Toki 和 Schizoporaceae Jülich 是半知菌目(Hymenochaetales)中物种最丰富的科,大韩民国的大多数物种都属于这两个科。因此,目前的分类和命名方法并没有反映出其余半知母科中的物种。本研究开展了基于形态学和多基因标记的系统发育调查,首先是全面鉴定韩国未被充分研究的半知母科标本,其次是反映物种分类的更新。系统发生分析评估了五个遗传标记:核小亚基核糖体 DNA(nSSU)、内部转录间隔(ITS)、核大亚基核糖体 DNA(nLSU)、RNA 聚合酶 II 亚基 2 基因(RPB2)和翻译伸长因子 1 基因(TEF1)。系统进化分析结果支持韩国的 8 个科(不包括金丝桃科和五味子科)中的 18 个物种。根据最近的分类学重建,对以前归入 Rickenellaceae 和 Trichaptum sensu lato 的物种进行了系统修订。此外,我们的研究结果还发现了一个新种--伞形瑞肯瑞拉(Rickenella umbelliformis),并鉴定了五个以前国内未报道的物种,它们被归入五个未充分研究的科。我们的研究结果有助于更好地了解金膜甲藻的多样性,并强调了继续研究的必要性。

Phylogenetic Assessment of Understudied Families in Hymenochaetales (Basidiomycota, Fungi)-Reporting Uncovered Species and Reflecting the Recent Taxonomic Updates in the Republic of Korea.

Phylogenetic Assessment of Understudied Families in Hymenochaetales (Basidiomycota, Fungi)-Reporting Uncovered Species and Reflecting the Recent Taxonomic Updates in the Republic of Korea.

Hymenochaetales Oberw. is an order classified in Basidiomycota of Fungi, and species in this order display notable diversity. They exhibit various fruiting body shapes, including clavarioid, effused-reflexed, and resupinate basidiomes. Few mycorrhizal species have been reported in Hymenochaetales, but wood-decaying species dominate the order. Hymenochaetaceae Imazeki & Toki and Schizoporaceae Jülich are the most species-rich families within Hymenochaetales, and most species in the Republic of Korea belong to these two families. As such, current taxonomic classification and nomenclature are not reflected upon species in the remaining Hymenochaetales families. For this study, a multifaceted morphological and multigenetic marker-based phylogenetic investigation was conducted to, firstly, comprehensively identify understudied Hymenochaetales specimens in Korea and, secondly, reflect the updates on the species classification. Five genetic markers were assessed for the phylogenetic analysis: nuclear small subunit ribosomal DNA (nSSU), internal transcribed spacer (ITS), nuclear large subunit ribosomal DNA (nLSU), RNA polymerase II subunit 2 gene (RPB2), and translation elongation factor 1 gene (TEF1). The results from phylogenetic analysis supported 18 species classified under eight families (excluding Hymenochaetaceae and Schizoporaceae) in Korea. Species formerly placed in Rickenellaceae and Trichaptum sensu lato have been systematically revised based on recent taxonomic reconstructions. In addition, our findings revealed one new species, Rickenella umbelliformis, and identified five formerly nationally unreported species classified under five understudied families. Our findings contribute to a better understanding of Hymenochaetales diversity and highlight the need for continued research.
