Lecythium granulatus, 100 µm
Lecythium granulatus (Schulze, 1875)
The photomicrographs on this page show several specimens of Lecythium granulatus which all came from one sample. Those cells mainly preyed on several species of diatoms. Cell with large diatoms could be very large. In these cells the nucleus is pushed aside by the diatom (see image below).
Dividing cells?
The same cell focused at two different heights
Cell with filopodia network, branching and anastomosing
Three specimens after division
Pseudostome
Two specimens, one is trying to engulf a diatom.
Specimen with kind of shell, though not fully enveloping the cell
Two plate-like parts of what seems to be a kind of shell
Specimen with ingested zoochlorellae, robbed of a crashed Difflugia pyriformis.
This specimen showed curious behaviour. The fundus opened and a small speudopodium came out of the cell (see arrow). It moved a little and grew longer, after which it was retracted. It shows the possibility of the membrane to make an aperture.
