衣藻属（Volvocales，Chlorophyceae）是一个大的多系属，包括许多种，应被划分为独立的属。本研究旨在根据形态学和分子生物学数据，检查梅斯林衣原体的真实菌株和相关菌株。所有菌株都具有一个星状叶绿体，中央有一个蛋白核和半球形的乳头，但它们是不同的细胞和柱头形状的基础上。基于18 S rDNA，atpB，和psaB的分子系统发育分析表明，菌株代表了一个独特的亚支Chloromonadinia。ITS-2的二级结构支持将菌株分为4个种。根据这些结果，我们提出了一个新属，Paludistella，包括P. meslinii comb. nov.，绿柱孢P. chlorostelatta comb. nov.，不对称拟单胞菌P. asymetrica sp. nov.，和三角斑叶蝉P. trianguloculussp. nov.
Chlamydomonas (Volvocales, Chlorophyceae) is a large polyphyletic genus that includes numerous species that should be classified into independent genera. The present study aimed to examine the authentic strain of Chlamydomonas meslinii and related strains based on morphological and molecular data. All the strains possessed an asteroid chloroplast with a central pyrenoid and hemispherical papilla; however, they were different based on cell and stigmata shapes. Molecular phylogenetic analyses based on 18S rDNA, atpB, and psaB indicated that the strains represented a distinct subclade in the clade Chloromonadinia. The secondary structure of ITS-2 supported the separation of the strains into four species. Based on the results, we propose a novel genus, Paludistella, including P. meslinii comb. nov., P. chlorostelatta comb. nov., P. asymmetrica sp. nov., and P. trianguloculus sp. nov.
