Members of the Watanabea clade of Trebouxiophyceae are genetically diverse and widely distributed in all kinds of habitats, especially in most terrestrial habitats. Ten new strains of terrestrial algae isolated from the tropical rainforest in China, and four published strains were investigated in this study. Morphological observation and molecular phylogenetic analyses based on the 18S, ITS, rbcL, and tufA genes were used to identify the new strains. Four previously described species were reinvestigated to supplement molecular data and autospores' morphological photographs. The phylogenetic analyses based on 18S only, the concatenated dataset of 18S and ITS, as well as the concatenated dataset of rbcL and tufA, showed the same phylogenetic positions and relationships of these new strains. According to the phylogenetic analysis and morphological comparisons results, we described these 10 strains as four new members within the Watanabea clade, Polulichloris yunnanensis sp. nov., Polulichloris ovale sp. nov., Massjukichlorella orientale sp. nov., and Massjukichlorella minus sp. nov., and two known species, Massjukichlorella epiphytica, and Mysteriochloris nanningensis. Additionally, we provide strong evidence proving that Phyllosiphon, Mysteriochloris, Polulichloris, and Desertella all reproduce through unequal sized autospores.

:Trebouxiophyceae的Watanabea进化枝成员在遗传上是多样的,并且广泛分布在各种生境中,尤其是在大多数陆地生境中。从中国热带雨林中分离出十种新的陆地藻菌株,并研究了四种已发表的菌株。基于18S,ITS,rbcL和tufA基因的形态学观察和分子系统发育分析用于鉴定新菌株。对四个先前描述的物种进行了重新研究,以补充分子数据和自孢子的形态照片。仅基于18S的系统发育分析,18S和ITS的串联数据集以及rbcL和tufA的串联数据集显示了这些新菌株相同的系统发生位置和关系。根据系统发育分析和形态学比较结果,我们将这10个菌株描述为Watanabea进化枝,云南Polulichloris yunnanensis sp。中的四个新成员。十一月,卵圆孢菌。东方马氏藻11月。十一月,和Massjukichlorella minus sp.。十一月,和两个已知的物种,附生马氏藻和南宁的Mysteriochloris南宁。此外,我们提供了有力的证据证明,Phyllosiphon,Mysteriochloris,Poulichloris和Desertella均通过不等大小的自生孢子繁殖。
