Diplochlamys spec. 164 and 342 µm

Diplochlamys spec.

Diagnosis: Membranous shell, ranging from hemispherical to spherical, greyish-yellow, and bilayered; inner hyaline sac enclosing the cell with flexible aperture; outer layer is more rigid, composed of loosely arranged organic spheres. Size up to approximately 400 µm. Granular endoplasm; multinucleate, with spherical nuclei containing irregular nucleoli, dispersed throughout each nucleus.

Dimensions: 164—378 µm; nuclei approximately 18 µm

Ecology: Sphagnum, Austria (Mittermoor, Tirol)

Remarks: This undescribed species resembles D. vestita Penard, 1909, but is significantly larger. The nuclei of D. vestita are considerably smaller (3-5 µm) and have a different structure, with a single central nucleolus.
This new species was abundant in Sphagnum but proved difficult to manipulate due to a dense debris covering, making it extremely challenging to observe the cytoplasm, number of nuclei, and type of food. With some effort, I was able to press cytoplasm out of the membranous test. It appeared relatively clear and devoid of food particles.

Specimen pressed by the cover glass; some cytoplasm was squeezed out of the test. P = pseudostome; M = Inner membrane
