摘要

新幽门螺杆菌是一种具有产生生物活性次生代谢物潜力的幽门螺杆菌属。在对贵州和海南两省的幽门孢子真菌进行调查时,从淡水和陆生生境中分离出4株幽门孢子真菌。基于ITS、LSU、tef1-α和rpb2多基因系统发育数据和形态特征的综合分析,提出了aquissubtropicus和N. wuzhishanensis这两个新种。文中给出了新分类群的详细描述、插图和系统发育分析。此外,还提供了一份分子数据支持的目前公认的新螺杆菌物种清单。

Morphological and phylogenetic analyses reveal two new species of Neohelicomyces (Tubeufiales, Tubeufiaceae) from China.

Neohelicomyces is a genus of helicosporous hyphomycetes with the potential to produce bioactive secondary metabolites. During a survey of helicosporous fungi in Guizhou and Hainan provinces, southern China, four isolates were obtained from both freshwater and terrestrial habitats. Based on combined analyses of multigene phylogenetic data (ITS, LSU, tef1-α, and rpb2) and morphological characteristics, two novel species, Neohelicomyces aquisubtropicus and N. wuzhishanensis, are proposed. Detailed descriptions, illustrations, and phylogenetic analyses of the new taxa are presented. Additionally, a checklist of currently accepted Neohelicomyces species supported by molecular data is provided.
