摘要

本文报道了从俄罗斯北部(亚极地乌拉尔)的一条冷水山溪中分离到的绿藻纲Mychonastes frigidus sp. nov.一新种。用形态学和分子学方法对该分类群进行了描述。嗜冷mychonastus sp. nov.属于嗜冷mychonastus属的一种，具有球形的单细胞。比较ITS2 rDNA序列及其二级结构，结合代偿性碱基变化方法，证实了Mychonastes frigidus sp. nov与该属其他物种的分离。冷藏mychonastusfrigidus sp. 11 .代表了一种只能用分子数据可靠地识别的神秘物种。

Mychonastes frigidus sp. nov. (Sphaeropleales/Chlorophyceae), a new species described from a mountain stream in the Subpolar Urals (Russia)

This paper describes a new species from the Class Chlorophyceae, Mychonastes frigidus sp. nov., isolated from a cold-water mountain stream in the north of Russia (Subpolar Ural). The taxon is described using morphological and molecular methods. Mychonastes frigidus sp. nov. belongs to the group of species of the genus Mychonastes with spherical single cells. Comparison of ITS2 rDNA sequences and its secondary structures combined with the compensatory base changes approach confirms the separation between Mychonastes frigidus sp. nov and other species of the genus. Mychonastes frigidus sp. nov. represents a cryptic species that can only be reliably identified using molecular data.
