Abstract

The species evolution of epiphytic fungi are unique and critically important due to their association with plants. In this study, six new species of Translucidithyrium were discovered re-integrated morphological characteristics of this genus combined with phylogenetic analyses. The phylogenetic analysis revealed that all species of Translucidithyrium formed a monophyletic clade within Phaeothecoidiellaceae. The molecular clock analysis indicated that the divergence time of extant species of Translucidithyrium occurred during the Cenozoic era (18 Mya). The cophylogeny was conducted based on separately phylogenetic trees of Translucidithyrium and its host plants to explore their evolutionary relationships. Translucidithyrium's species with host plant selection likely being random. Understanding the evolutionary history of Translucidithyrium species provides new perspectives and data to support research into the evolution of epiphytic fungi.

中国透光菌属（Mycosphaerellales, phaeotheecoidiellaceae）的多样性及其进化分裂时间和共生系的研究

附生真菌的物种进化是独特的和至关重要的，因为它们与植物的关系。本研究发现了6个新种，重新整合了该属的形态特征并结合系统发育分析。系统发育分析表明，所有的透光菌属属都是辉石菌科的一个单系分支。分子钟分析表明，现存Translucidithyrium的分化时间发生在新生代（18mya）。通过分别构建透光菌及其寄主植物的系统发育树，探讨二者的进化关系。带寄主植物选择可能是随机的。了解Translucidithyrium物种的进化史为研究附生真菌的进化提供了新的视角和数据。
