摘要 被毛菌是全球分布的昆虫病原真菌,在生物防治和生物医学方面具有重要的经济应用。 2011年,受多形性真菌双重命名法终止的影响,被毛菌被抑制,取而代之的是麦冬虫草属。目前,被毛菌已作为麦冬虫科下的一个属复活。在这项研究中,我们根据形态学和系统发育分析介绍了被毛菌的两个新种。被毛菌和宽阔水菌对中国不同种类的鳞翅目幼虫具有致病性。被毛菌与相关物种的主要区别在于其锥状基部;颈部细长,24–40.8 × 2.2–2.5 μm;长而窄的伞形或纺锤体分生孢子,6.5–10 × 2.1–4.3 μm。 Hirsutellakuankuoshuiensis 有两种类型的管瓶和独特的 9.9–12.6 × 2.7–4.5 μm、棒状或肉芽状分生孢子。讨论了新物种之间的区别以及与其他被毛菌物种的系统发育关系。
Abstract Hirsutella are globally distributed entomopathogenic fungi that offer important economic applications in biological control and biomedicine. Hirsutella was suppressed in favour of Ophiocordyceps affected by the ending of dual nomenclature for pleomorphic fungi in 2011. Currently, Hirsutella has been resurrected as a genus under Ophiocordycipitaceae. In this study, we introduce two new species of Hirsutella, based on morphological and phylogenetic analyses. Hirsutellaflava and H.kuankuoshuiensis are pathogenic on different species of larval Lepidoptera in China. Hirsutellaflava primarily differs from related species by its awl-shaped base; long and narrow neck, 24–40.8 × 2.2–2.5 μm; long and narrow cymbiform or fusoid conidia, 6.5–10 × 2.1–4.3 μm. Hirsutellakuankuoshuiensis has two types of phialides and distinctive 9.9–12.6 × 2.7–4.5 μm, clavate or botuliform conidia. The distinctions amongst the new species and phylogenetic relationships with other Hirsutella species are discussed.
