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 95-145 µm, my measurements 103-125 µm.

Ecology: In mosses and Sphagnum, in peaty bogs.

Shell structure of P. lageniformis (l) and shell structure of Trinema enchelys present in the same sample.

This shell of P. lageniformis was found in a moss sample from Ecuador. It had obviously the same structure as shells of Trinema enchelys, which were present in the same sample. It is well known that these species get their xenosomes from preyed testaceans, but it is remarkable that the Trinema-structure was copied.
