Serial observations were carried out on cultures of five morphospecies of the genus Microcystis Kützing ex Lemmermann 1907, Microcystis aeruginosa (Kützing) Kützing, Microcystis ichthyoblabe Kützing, Microcystis novacekii (Komárek) Compére, Microcystis viridis (A. Brown) Lemmermann, and Microcystis wesenbergii (Komárek) Komárek in Kondratieva. Many strains maintained colony forms characteristic of their morphospecies, and others showed morphological variations, some of which were characteristic of other morphospecies. M. novacekii displayed several morphotypes including some characteristics of M. aeruginosa and M. ichthyoblabe. M. wesenbergii also showed great morphological variability and showed morphotypes characteristic of M. aeruginosa. Distinction among these morphospecies, therefore, seemed to be obscure or impossible. We conclude that the current classification of the genus Microcystis, chiefly based on morphological characteristics, is no longer valid and must be reviewed in light of our observations that one strain may have various colony forms.
对1907年勒默尔曼描述的微囊藻属（Microcystis Kützing ex Lemmermann）的五个形态种，即铜绿微囊藻（Microcystis aeruginosa (Kützing) Kützing）、鱼害微囊藻（Microcystis ichthyoblabe Kützing）、诺氏微囊藻（Microcystis novacekii (Komárek) Compére）、绿色微囊藻（Microcystis viridis (A. Brown) Lemmermann）和惠氏微囊藻（Microcystis wesenbergii (Komárek) Komárek）在孔德拉季耶娃的培养物进行了连续观察。许多菌株保持着其形态种特有的群体形态，而其他一些则表现出形态变异，其中一些是其他形态种的特征。诺氏微囊藻表现出几种形态型，包括一些铜绿微囊藻和鱼害微囊藻的特征。惠氏微囊藻也表现出很大的形态变异性，并呈现出铜绿微囊藻特有的形态型。因此，这些形态种之间的区分似乎模糊不清或无法区分。我们得出结论，目前主要基于形态特征的微囊藻属分类不再有效，必须根据我们的观察结果进行重新审视，即一个菌株可能具有多种群体形态。
