Abstract

In this study, we studied the diversity of occurring in soil collected along the Woodville Big Tree Forest Trail situated close to the coastal town of Wilderness in South Africa. Strains were accessioned into a collection and then identified to species based on β-tubulin DNA sequences, which is the recommended DNA barcode for the genus. The 74 strains were found to represent 18 species, including six we consider undescribed. Here, we introduce them as , and . Phylogenetic comparisons were made, and genealogical concordance was demonstrated for these new species using DNA sequences from nuc rDNA internal transcribed spacer region ITS1-5.8S-ITS2 (ITS barcode), β-tubulin, calmodulin, and RNA polymerase II second largest subunit. Notes on morphological characters distinguishing the new species from their close relatives are provided.

摘要

在本研究中,我们研究了南非沿海荒野镇附近的伍德维尔大树林小径沿线土壤中存在的多样性。将菌株采集到一个收藏集中,然后根据β-微管蛋白 DNA 序列鉴定为物种,这是该属推荐的 DNA 条码。这 74 株菌代表了 18 个种,其中包括我们认为未描述的 6 个种。在这里,我们将它们介绍为 、 、 和 。使用来自核 rDNA 内部转录间隔区 ITS1-5.8S-ITS2(ITS 条码)、β-微管蛋白、钙调蛋白和 RNA 聚合酶 II 大亚基的 DNA 序列进行了系统发育比较,并证明了这些新物种之间的系统发育一致性。提供了区分新种与其近缘种的形态特征说明。
