金影藻属Aureoumbra
该属的 泻湖镇金影藻Aureoumbra lagunensis还是本纲中唯二能形成赤潮的物种

远斑藻属Pelagospilus

马尾藻球藻属Sargassococcus（图1
该属附着在马尾藻上生活，因此得名
金裂藻属Aureoscheda（图2
该属形成片状群体，这两个属构成了一个又一次起源底栖生活的演化支

金蜘藻属Arachnochrysis（图1
该属叶绿体有八个裂片，像蜘蛛一样，因此得名。他们形成不规则的大型多细胞胶质群体，他与后文的四个属都属于同一个独立的底栖化支系。（具体的演化关系还是请看系统发生树）
金肉藻属Sarcinochrysis（图2，3）
拥有壮观的大型囊状多细胞藻体（胶质

安德森藻属Andersenia（图1，2）
拟金线藻属Nematochrysopsis（图3，4）
金云藻属Chrysonephos（图5，6，7）
这三个属不是囊状多细胞，而是演化为了链状多细胞，拟金线藻属和金云藻属的藻体还会分叉，因此可以长到很壮观的绒树状的群落
