Amoeboid of the month

 

Difflugia oblonga
This drawing is part of the original description of Difflugia oblonga. It was described by Christian Gottfried Ehrenberg in 1838. All drawings show the same specimen. The smooth test is 110 µm long. If you look through the literature you will discover that many Difflugia tests have been identified as D. oblonga, but most of them are misidentified. They are much larger and have a different shape.
