Abstract

Two fungal strains (KNU-JJ-1827 and KNU-JJ-1829) belonging to the class Dothideomycetes were discovered from Jeju Island, Korea during this investigation of soil microfungi. Strain KNU-JJ-1827 showed fewer conidial septations, larger conidiogenous cells, and smaller conidia compared to the previously identified closest species of Didymocyrtis. Strain KNU-JJ-1829 revealed the similar characteristics of the nearest certain species of the genus Parathyridaria with the production of conidiogenous cells and conidia, because no asexual morphs were detected from the closest type strain Parathyridaria rosae. The novelty of the strains was also confirmed by analyzing molecular data using internal transcribed spacer regions and 28S rDNA. The molecular phylogeny also strongly support the detailed description and illustration for each proposed species as Didymocyrtis septata sp. nov. (KNU-JJ-1827) and Parathyridaria ellipsoidea sp. nov. (KNU-JJ-1829) isolated from soil in Korea.

摘要

在对土壤微真菌的调查中，从韩国济州岛发现了两种属于真菌纲的菌种（KNU-JJ-1827和KNU-JJ-1829）。应变KNU-JJ-1827表现出较少的分生孢子septations，较大的产孢细胞，小孢子相比，先前确定的最近物种Didymocyrtis。菌株KNU-JJ-1829揭示了甲状旁腺属中最接近的某些物种与分生孢子细胞和分生孢子的相似特征，因为未从最接近型的玫瑰甲状旁腺中检测到无性形态。。通过使用内部转录的间隔区和28S rDNA分析分子数据，也证实了该菌株的新颖性。分子系统发育学也强烈支持对每个拟定物种（Dydymocyrtis septata sp。）的详细描述和图解。十一月 （KNU-JJ-1827）和Parathyridaria ellipsoidea sp。十一月 （KNU-JJ-1829）从韩国土壤中分离出来。
