Sinus linear, closed for the greater part. Semicells in frontal view subcirculair with a slightly flattened apex. Each semicell with 16, almost equally sized marginal crenations. Cell wall ornamentation consisting of 3–4 concentric series of submarginal rounded verrucae as well as 2–3 irregular, transversal rows of granules or short costae just above the isthmus. In between the submarginal and the supraisthmial ornamentation the cell wall is unsculptured. Cells in lateral view elliptic with a shallow, widely open, median invagination. Semicells in lateral view somewhat ovoid with a slight, basal inflation about 1/3 distance from the median invagination. Semicells in apical view ellipsoid with broadly rounded poles and a slight median inflation. Chloroplast with a single, central pyrenoid. Dimensions: cell length 32–37 μm, cell breadth 23–26μm, cell thickness 18–19μm, breadth of isthmus 12–14μm.</paragraph>

, etc., species of which quite a series of infraspecific taxa have been described. Our alga, readily to be recognized by the regularly wrinkled, subcircular outline of the semicells, could not be matched with any known species in a satisfactory way. All of the above-mentioned taxa are characterized by a semi-elliptic to pyramidal outline of the semicell, not a subcircular one. As our alga was found to be but little variable in shape and occurred in six out of the nine localities sampled (1, 2, 3, 4, 5 and 8), we think it justified to describe it as a new species.
