摘要绿蛛类植物有第三种，球状绿蛛Cllorarachnion lobosum sp.11月，在关岛的增菌培养中发现。在生命周期的大部分时间里，该物种是球状的，具有明显的壁。阿米巴样细胞缺失。质周室的一个非常薄的延伸部分将类蛋白核基质分成两个纵向的部分，核形态位于类蛋白核的底部。这些特征区别于CH。从绿僵菌中提取的球状物。这两种生物共有以下特征：(1)每个细胞都有几个含有叶绿素a和b的叶绿体；(2)每个叶绿体被两对膜所包围；(3)存在明显的突起的蛋白核；(4)游动孢子有一个鞭毛缠绕在细胞体周围。
Abstract A third species of chlorarachniophyte, Chlorarachnion globosum sp. nov., was discovered in enrichment cultures from Guam. During most of the life cycle this species is coccoid with a distinct wall. Amoeboid cells are absent. A very thin extension of the periplastidial compartment divides the pyrenoid matrix into two longitudinal halves and the nucleomorph is located at the base of the pyrenoid. These features distinguish Ch. globosum from Chlorarachnion reptans Geitler. The two organisms share the following features: (1) each cell has several chloroplasts containing chlorophyll a and b; (2) each chloroplast is surrounded by two pairs of membranes; (3) a distinct projecting pyrenoid is present; (4) the zoospore has a single flagellum coiling around the cell body.
