Abstract

A new species of green coccoid algae, Mychonastes hindakii sp. nov., was isolated from the River Moscow (Russia, Moscow). The taxon is described using morphological and molecular methods. Mychonastes hindakii sp. nov. belongs to the group of species of the genus Mychonastes with spherical single cells joined with mucilaginous, irregularly shaped stalks. A comparison of ITS2 rDNA sequences and its secondary structures combined with the compensatory base changes approach confirms the separation between Mychonastes hindakii and other species of the genus. Mychonastes hindakii sp. nov. represents a cryptic species that can only be reliably identified using molecular data.

摘要

一种新的绿色球藻——辛氏微囊藻（Mychonastes hindakii sp. nov.），从莫斯科河（俄罗斯，莫斯科）分离得到。采用形态学和分子方法对该分类单元进行了描述。辛氏微囊藻属于微囊藻属物种群，具有球形单细胞，通过粘液质、形状不规则的柄相连。ITS2 rDNA序列及其二级结构的比较结合补偿性碱基变化方法证实了辛氏微囊藻与该属其他物种之间的差异。辛氏微囊藻是一种隐性物种，只能通过分子数据可靠鉴定。
