Temporary name till it is published. This could also be a Luffisphaera species
This small cercozoan came up in wet mounts kept in moist chambers for some days. I’ve found it at several locations in oligotrophic and mesotrophic fresh waters, like Crailoo and ‘t Loo, both in the Netherlands, and in a small stream in Bretagne, France. It This cercozoan has filopodia, like Pseudodifflugia, and a bowl shaped test with a large aperture. The test is composed of particles which look like birds heads: a sphere with a pointed spine (see arrowheads), which in SEM show a triangular sheet with a network shaped structure (see below).
