Abstract

Abstract This study introduces two new marine microfungal species, Paraloratospora marina (Phaeosphaeriaceae) and Tremateia phragmitis (Didymosphaeriaceae) based on morphological comparisons and multi-gene phylogenetic analyses. They were collected on decaying woody stems of Phragmites australis at Cardiff Bay Nature Reserve in Wales, United Kingdom. Paraloratospora marina sp. nov. is characterized by immersed, globose to subglobose ascomata with a papillate and periphysate ostiole, cylindrical to subcylindrical, thick-walled, sessile to subsessile asci, fusiform, hyaline to pale brown, 3-septate, guttulate ascospores. Tremateia phragmitis sp. nov. is characterized by semi-immersed to immersed, globose ascomata with a protruding periphysate ostiole, clavate, pedicellate, asci and ascospores that are ellipsoidal to broadly fusiform, 4–6 transversely septate, with 1–2 vertical septa, muriform, golden brown to pale brown ascospores. Dichotomopilus funicola and Pseudofusicoccum ardesiacum are recorded for the first time from marine habitats. Furthermore, based on morphological characteristics and multigene phylogenetic analyses, Phaeosphaeria spartinae was transferred to Septoriella.

基于分类和系统发育评价的新型河口子囊菌群特征

摘要本研究通过形态学比较和多基因系统发育分析，介绍了两个新的海洋微真菌物种，Paraloratospora marina（Phaeospeeriaceae）和Tremateia phragmatis（Didymosphaeriaceae。它们是在英国威尔士卡迪夫湾自然保护区的芦苇腐烂的木质茎上采集的。Paraloratospora marina sp.nov.的特征是浸入的、球状至近球形的子囊，具有乳头和外周孔，圆柱形至近圆柱形，厚壁，无柄至近无柄的腹水，纺锤形，透明至浅棕色，3-间隔，具滴状子囊孢子。银耳菌（Tremateia phragmitis sp.nov。首次从海洋生境中记录到钩尾二叉虫和硬脊假梭尾虫。此外，基于形态学特征和多基因系统发育分析，将裂叶Phaeospeeria spartinae转移到Septoriella。

期刊介绍： Botanica Marina publishes high-quality contributions from all of the disciplines of marine botany at all levels of biological organisation from subcellular to ecosystem: chemistry and applications, genomics, physiology and ecology, phylogeny and biogeography. Research involving global or interdisciplinary interest is especially welcome. Applied science papers are appreciated, particularly when they illustrate the application of emerging conceptual issues or promote developing technologies. The journal invites state-of-the art reviews dealing with recent developments in marine botany.
