摘要

在分子系统发育成为真菌分类学主导证据的时代,真菌的形态学分类框架得到了很大的更新。与其他真菌类群相比,大型真菌在序列和水平上的更新较少。在这项研究中,研究了一个鲜为人知的大型担子菌属Xenasmatella的分类位置。系统发育和分子钟分析从7个位点数据集推断,支持属代表一个顺序等级谱系。据此,在菌类中新引入了Xenasmatellales单型目和Xenasmatellaceae单型科。通过对四位点数据的系统发育分析,进一步阐明了异种蝇的物种多样性和亲缘关系。根据其形态特征,描述了一新种异种马蹄莲。此外,还扩大了以前只在中国云南省发现的ailaoshanxenasmatella、gossypina和wuliangshanx的分布范围。此外,还发现了来自澳大利亚维多利亚州和中国四川的两个未命名的单标本谱系,可能代表了该属的两个潜在新种。综上所述,本研究更新了真菌的分类框架,为全面了解真菌的进化史提供了重要的补充。

Xenasmatellales ord. nov. and Xenasmatellaceae fam. nov. for Xenasmatella (Agaricomycetes, Basidiomycota).

In the era of molecular phylogeny as dominant evidence in fungal taxonomy, the taxonomic framework of fungi adopted from morphological characteristics has been largely updated. Compared with other fungal groups, macrofungi underwent fewer updates at the order and higher level. In this study, the taxonomic placement of a poorly known macro-basidiomycetous genus Xenasmatella is studied. Phylogenetic and molecular clock analyses inferred from a seven-locus dataset support that the genus represents an order rank lineage. Accordingly, a monotypic order Xenasmatellales and a monotypic family Xenasmatellaceae are newly introduced for Xenasmatella within Agaricomycetes. The species diversity and relationships of Xenasmatella are further clarified with the aid of the phylogenetic analysis inferred from a four-locus dataset. In association with morphological characteristics, a new species Xenasmatella hjortstamii is described. Moreover, the distribution of Xenasmatella ailaoshanensis, X. gossypina, and X. wuliangshanensis previously known only from type localities in Yunnan Province, China are expanded. In addition, two unnamed single-specimen lineages of Xenasmatella from Victoria State, Australia and Sichuan, China are revealed, likely representing two potential new species of this genus. In summary, the current study updates the taxonomic framework of Agaricomycetes and provides a crucial supplement for comprehensively understanding the evolutionary history of this fungal class.
