Abstract

Vaginatispora acrostichi sp. nov. was isolated from submerged stems of Acrostichum aureum (Pteridaceae) collected from the mangrove habitats of Pranburi District, Prachuap Khiri Khan, Thailand. Phylogenetic analyses based on the combined dataset of LSU, SSU, ITS, tef1-α, rpb2, and β-tub sequences placed the novel species within Vaginatispora. Vaginatispora acrostichi formed a well-supported sister clade with V. lignicola but differs from it morphologically and phylogenetically. Vaginatispora acrostichi is distinguishable from V. lignicola by ascospore size, septation and colour. The ascospores of V. acrostichi turn light brown at maturity and have a single septum with a minute constriction, while those of V. lignicola appear yellowish at maturity and have 1–3 septa with pronounced constriction. Vaginatispora acrostichi is introduced in this paper as a novel species with a comprehensive description and illustration.

基于形态学和多基因系统发育的新物种 Vaginatispora acrostichi（Lophiostomataceae）介绍

Vaginatispora acrostichi sp.nov.是从泰国Prachuap Khiri Khan市Pranburi区红树林栖息地采集的Acrostichum aureum（翼手目）沉水茎中分离出来的。基于 LSU、SSU、ITS、tef1-α、rpb2 和 β-tub 序列组合数据集的系统发生分析将该新物种归入 Vaginatispora 类。Vaginatispora acrostichi 与 V. lignicola 形成了一个支持良好的姊妹支系，但在形态和系统发育上与之不同。Vaginatispora acrostichi 与 V. lignicola 的区别在于腹孢子的大小、隔膜和颜色。V. acrostichi 的无孢子成熟时变成浅棕色，有一个单隔膜和微小的缢缩，而 V. lignicola 的无孢子成熟时呈淡黄色，有 1-3 个隔膜和明显的缢缩。本文介绍了 Vaginatispora acrostichi 这一新种，并对其进行了全面描述和说明。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
