    The valve morpholofy and ultrastructure of the so-called /"stelligeroid/" taxa of the genus Cyclotella (Kützing) Brébisson (Bacillariophyceae) are discussed. These taxa have marginal fultoportulae and the rimoportula(e) positioned between costae. As this and ohter discussed characters do not fit the current description of the genus Cyclotella (Kützing) Brébisson nom.cons., the formal transfer of these taxa into a new genus, Discostella gen. nov., is proposed

    Je diskutována morfologie a ultrastruktura valv tzv. "stelligeroidních" taxonů rodu Cyclotella (Kützing)Brébisson (Bacollariophyceae).Taxony této skupiny mají fultoportuly okrajové části valvy umístěny mezi žebry. Protože tento a další diskutované znaky se neshodují se současným popisem rodu Cyclotella (Kützing) Brébisson nom. cons., je navržen formální převod těchto taxonů do nového rodu, Discostella gen. nov
