“变形虫”网状变形虫。gen.，n.从希腊锡拉岛（Santorin）的沿岸的海域采集的样品中分离得到一株细菌。可与羽状硅藻Amphiprora sp.共育。在硅藻的“草坪”上，变形虫阶段形成集群。每一个集群包含一个单一的变形虫聚集硅藻与它的网状足。当硅藻密度较低时，不同变形虫的网足相互融合，形成一个“摄食群落”。芽生网状阿米巴的增殖需要芽的连续形成，芽可以转化为双鞭毛虫或游动孢子。网状足的消化过程，游动孢子发生和游动孢子的形态表现出惊人的相似性的meroplasmodial种Leucodictyon marinum（GRELL 1991 a），表明关系。
The ''amoeboflagellate'' Reticulamoeba gemmipara n. gen., n. sp. was isolated from samples which were collected in the littoral zone of the Greek island Thera (Santorin). It could be cultivated with the pennate diatom Amphiprora sp. as food organism. On a ''lawn'' of the diatoms, the amoeboid stages create clusters. Every cluster contains a single amoeba which gathers the diatoms with its reticulopodia. When the density of the diatoms is low, the reticulopodia of different amoebae fuse with each other to form a ''feeding community''. The multiplication of Reticulamoeba gemmipara entails the successive formation of buds which can transform into biflagellate swarmers or zoospores. The course of reticulopodial digestion, zoosporogenesis and the morphology of the zoospores exhibit a striking similarity to the meroplasmodial species Leucodictyon marinum (GRELL 1991 a), indicating a relationship.
