Padaungiella wailesi (Deflandre, 1936)

Diagnosis: Body of shell broad, ellipsoid, prolonged into a tubular neck. Large elliptic or polygonal rounded plates, sometimes intermixed with small polygonal scales.

Dimensions: Length 75-100 µm, my measurements 103 µm.

Ecology: In mosses and Sphagnum.

Remarks: Kosakyan et al., 2025: “Padaungiella wailesi and P. lageniformis show a continuum of neck shapes ranging from the side generally tapering towards the aperture to the presence of a bulge in the middle of the neck. It remains unclear if this corresponds to intraspecific variability or points to the existence of some hitherto undescribed species. We maintain P. wailesi as an inquirenda species until P. lageniformis and its closely related species can be studied using more detailed morphological and molecular analyses.
