Abstract：
The species within the family Cunninghamellaceae during an investigation of soil microfungi in Korea, in which three strains were isolated from Gangwon, Chungbuk, and Gyeongbuk provinces, designated as KNUF-22-121A, KNUF-22-126A, and KNUF-22-316, respectively. Because the morphological and molecular analyses of these three strains were identical, KNUF-22-316 underwent further detailed study. Phylogenetic analyses based on the concatenated nucleotide sequences of the internal transcribed spacer region and the large subunit 28S rRNA gene revealed that the strain belonged to the genus Absidia, but occupied a distinct phylogenetic position. The strain KNUF-22-316 was compared with closely related species Absidia radiata CGMCC 3.16257T and Absidia yunnanensis CGMCC 3.16259T, morphologically different with shorter sporangiophores, smaller sporangia and columellae, and the consistent presence of collars. Here, we provide a detailed description and images of this proposed new species, which we have named Absidia microsporangia sp. nov.
摘要：
在韩国调查土壤微真菌期间，杉木科中的物种，其中从江原分离出三个菌株，忠北,和庆北省，指定为KNUF-22-121A，KNUF-22-126A,和KNUF-22-316。因为这三个菌株的形态和分子分析是相同的，KNUF-22-316进行了进一步的详细研究。基于内部转录间隔区和大亚基28SrRNA基因的串联核苷酸序列的系统发育分析表明，该菌株属于Absidia属，但占据了独特的系统发育位置。将菌株KNUF-22-316与密切相关的物种AbsidiaCGMCC3.16257T和云南AbsidiaCGMCC3.16259T进行了比较，形态上与较短的孢子囊不同，较小的孢子囊和小柱,以及项圈的持续存在。这里,我们提供了这个新物种的详细描述和图像，我们将其命名为Absidia微孢子囊。11月。
