So far, I have found only a few specimens of Staurastrum suchlandtianum in the Mühlweiher Litzestetten. This location is quite unusual, as Lenzenweger (1997) describes this species as Staurastrum bicoronatum var. alpinum and indicates its distribution area as the shore regions of mountain lakes at about 1500 m altitude.

Identification is best achieved with the apical view of the three-armed symmetry of Staurastrum suchlandtianum. The distal ends of the 3 arms each bear 3 spines. At about halfway along the arms, there are two double-pointed spines each, and around the center, 6 short double points group together in a circle (s. fig. 1 a).

In lateral view, one can see that the arms are slightly curved toward the equator. The apices are slightly convex, and the short double points can be seen there in lateral view (s. fig. 2 a-d).
