Abstract

Hypocreales is one of the largest orders within the class Sordariomycetes and is renowned for its diversity of lifestyles, encompassing plant, insect, and human pathogens, as well as endophytes, parasites, and saprobes. In this study, we focused on saprobic hypocrealean fungi isolated from rice in northern Thailand. Species identification was conducted using morphological characteristics and multilocus phylogenetic analyses, including the internal transcribed spacer region (ITS), 28S large subunit nuclear ribosomal DNA (LSU), translation elongation factor 1-alpha (1-α), RNA polymerase II second-largest subunit (2), and calmodulin (). This research confirmed the presence of 14 species of hypocrealean taxa, viz. (9), (1), (2), (1), and (1). Among these were two new species ( and ), four new host records (, , , and ), and three new geographical records (, , and ).

摘要

肉座菌目是粪壳菌纲中最大的目之一，以其多样的生活方式而闻名，包括植物、昆虫和人类病原体，以及内生菌、寄生虫和腐生菌。在本研究中，我们重点关注从泰国北部水稻中分离出的腐生肉座菌目真菌。使用形态特征和多位点系统发育分析进行物种鉴定，包括内转录间隔区（ITS）、28S大亚基核糖体DNA（LSU）、翻译延伸因子1-α（1-α）、RNA聚合酶II第二大亚基（2）和钙调蛋白（）。本研究证实存在14种肉座菌目分类单元，即（9种）、（1种）、（2种）、（1种）和（1种）。其中有两个新物种（和）、四个新寄主记录（、、、和）以及三个新地理记录（、、和）。
