Since the first phylogenetic study of the order Batrachospermales, Batrachospermum was shown to be paraphyletic. Subsequently, sections of the genus have been methodically investigated using DNA sequences and morphology in order to propose new genera and delineate species. Batrachospermum section Turfosa is the last section with multiple species yet to be examined. New sequence data of specimens from Europe and the United States were combined with the sparse sequence data already available. Phylogenetic analyses using rbcL and COI‐5P sequences showed this section to be a well‐supported clade, distinct from Batrachospermum section Batrachospermum and its segregate genera. Section Turfosa is raised to the generic rank as Paludicola gen. nov. Substantial genetic variation within the genus was discovered and 12 species are recognized based on DNA sequence data as well as morphological characters and geographic distribution. The following morphological characters were applied to distinguish species: branching pattern (pseudodichotomous or irregular), whorl size (reduced or well developed), primary fascicles (curved or straight), spermatangia origin (primary or secondary fascicles), and carposporophyte arrangement (loose or dense). Previously published species were transferred to the new genus: P. turfosa, P. keratophyta, P. orthosticha, P. phangiae, and P. periploca. Seven new species are proposed as follows: P. groenbladii from Europe; P. communis, P. johnhallii, and P. leafensis from North America; and P. aquanigra, P. diamantinensis, and P. turfosiformis from Brazil. In addition, three unsequenced species in the section, P. bakarensis, P. gombakensis, and P. tapirensis, were transferred to the new genus.

Paludicola gen。十一月 和修改以前在草假单胞菌节（Batrachospermales，Rhodophyta）中的物种。

自从首次对Batrachospermales进行系统发育研究以来，Batrachospermum被证明是共生的。随后，使用DNA序列和形态学系统地研究了该属的各个部分，以提出新的属和描述种。串珠节Turfosa是最后一节有多个物种还有待检验。来自欧洲和美国的标本的新序列数据与已经可用的稀疏序列数据相结合。使用系统发生分析RBC L和COI-5P序列显示此部分是一个良好支持进化枝，从不同串珠部串珠和其偏析属。部分 Turfosa被提升为Paludicola gen的通用级别。十一月 发现该属内的大量遗传变异，并根据DNA序列数据以及形态特征和地理分布识别了12种。应用以下形态学特征来区分物种：分支模式（假二分体或不规则），轮径（缩小或发育良好），初级分束（弯曲或直形），精原细胞起源（初级或次级分束）和软骨小体排列（疏松或稠密）。此前公布的物种转移到新属：P. turfosa，P. keratophyta，P. orthosticha，P. phangiae，和体育。提出了七个新物种，分别是：欧洲的罗汉果；P. communis，P。johnhallii和P. leafensis来自北美；和P. aquanigra，P. diamantinensis和P. turfosiformis来自巴西。此外，该部分中的三个未排序物种分别为巴卡氏菌（P. bakarensis），冈巴氏菌（P. gombakensis）和tap虫（P. tapirensis），已转移到新属中。
