Field characteristics

Cyst of Biecheleria baltica (Kremp et al., 2005) Moestrup et al., 2009

Field characteristics:
Spherical cysts covered with numerous solid short orthogonal protusions. The numerous alveolar vesicles that are typical for the motile can be reflected on the cyst wall. Archeopyle unknown

Dimensions: 20 - 30 µm
Stratigraphic range: Recent

Comparison with other species:
Cyst of Biecheleria baltica differ from those of Biecheleria cincta in being larger and not having a round archeopyle. It differs from the other transparant species with solid processes in having small spines that are not acuminate, branched or conical.

It is observed in the Baltic and probably related to low saline surface water conditions.
