Abstract

The aim of this study was to characterize a new fungal species, Acremonium conglutinatum, isolated from air samples collected in Wando, South Korea. Phylogenetic analysis based on the internal transcribed spacer and large subunit regions revealed its unique position within the genus Acremonium. The isolated strain displayed distinct morphological characteristics, including ellipsoid or bent-ellipsoid conidia formed in clusters on the phialides. These features differentiate the new species from closely related species within the genus. This study describes the morphological and molecular characteristics of A. conglutinatum and emphasizes its phylogenetic relationships with other Acremonium spp. The identification of this novel species contributes to our understanding of the diversity and ecological role of Acremonium.

摘要

本研究的目的是鉴定从韩国莞岛收集的空气样本中分离出的一种新真菌，即顶顶孢菌。基于内部转录间隔区和大亚基区域的系统发育分析揭示了其在顶孢霉属中的独特地位。分离的菌株表现出独特的形态特征，包括在瓶瓶上形成簇状的椭圆形或弯曲椭圆形分生孢子。这些特征将新物种与该属内密切相关的物种区分开来。这项研究描述了A. conglutatinum的形态和分子特征，并强调了它与其他顶孢霉属的系统发育关系。这一新物种的鉴定有助于我们了解顶孢霉属的多样性和生态作用。
