Hemichloris antarctica gen. et sp. nov. (Oocystaceae, Chlorococcales) is characterized by a single, articulated, pyrenoid-less, thick saucer-shaped chloroplast, which generally fills less than half of the cell periphery. Multiplication is only by autospores. The species is psychrophilic and is damaged at temperatures above 20 degree C. Hemichloris antarctica is a member of the cryptoendolithic microbial community living in porous sandstone rocks of the Antarctica cold desert. It inhabits the zone below that of cryptoendolithic lichens and survives at extremely low light intensities. In the natural habitat, morphology is somewhat different from that in culture, as chloroplasts are smaller and without articulation, and the cells develop a gelatinous sheath.

Hemichloris antarctica, gen. 等 sp. 十一月 (Chlorococcales, Chlorophyta)，一种来自南极洲的隐石藻类

Hemichloris antarctica gen. 等 sp. 十一月 (Oocystaceae, Chlorococcales) 的特征是单一的、铰接的、无核蛋白的、厚的碟形叶绿体，通常填充不到一半的细胞外围。繁殖仅通过自孢子进行。该物种嗜冷，在 20 摄氏度以上的温度下会受到损害。 Hemichloris antarctica 是生活在南极洲寒冷沙漠多孔砂岩中的隐石微生物群落的成员。它栖息在隐石内地衣以下的区域，并在极低的光照强度下存活。在自然栖息地中，形态与培养中的形态有些不同，因为叶绿体较小且没有关节，并且细胞形成凝胶状鞘。
