P. Komáromy, Zs.: Scotiella species (Chlorophyceae) and their theoretical life-cycle

The reproduction of Scotiella species occurs by autospores. However, in the earlier descriptions some obvious hesitations appear. In most cases, the authors drew their conclusions from certain phenomena. FRITSCH (1911) observed some cells of Sc. antarctica, which "... consist of a delicate, more or less oval membrane surrounding four oblong individuals of irregular shape, in some of which a pyrenoid was discernible". (I.e. p. 307) (Plate 1: Fig. 6.) In the case of 5c. polyptera FRITSCH (I.e.) said: "Only one case of possible reproduction was found a cell of Sc. polyptera, in which the outline of the wings had become obscure, contained a number of elongated protoplasmic masses, in one of which a pyrenoid was prominent." (I.e. p. 309) Plate II.
