通过光学和电子显微镜对丹麦沿海水域建立的培养物进行了描述，描述了金铬藻的一种新海洋物种，C. apheles。这些细胞是已知的所有金铬蛋白属中最小的细胞之一，尺寸约为。直径4 μm。基于连续切片，说明了一般精细结构，并详细描述了触体和鞭毛器的结构。以前没有在金铬藻的任何成员中详细检查过鞭毛根系统，显示它由四个微管根组成，而缺乏交叉带状根。观察到四个交叉带状纤维将鞭毛基部和触体基部互连。触体属于相当不寻常的六链类型。细胞体上存在两种看起来非常相似的小有机鳞片。其中包括有关 Chrysochromulina 模式种 C. parva 鞭毛根的未发表数据。 Chrysochromulina apheles 显然是世界性的。目前已经有蜂...
A new marine species of Chrysochromulina, C. apheles, is described from light and electron microscopy of a culture established from Danish coastal waters. The cells are among the smallest known in any species of Chrysochromulina, measuring ca. 4 μm in diameter. The general fine structure is illustrated and the structure of the haptonema and the flagellar apparatus is described in detail, based on serial sections. The flagellar root system, not previously examined in detail in any member of Chrysochromulina, is shown to consist of four microtubular roots, while cross-banded roots are lacking. Four cross-banded fibres were seen to interconnect the flagellar bases and the haptonema base. The haptonema belongs to the rather unusual six-stranded type. Two very similar looking types of small organic scales are present on the cell body. Unpublished data on the flagellar roots of the type species of Chrysochromulina, C. parva, are included. Chrysochromulina apheles is apparently cosmopolitan. It has presently bee...
