Microchlamys patella (Claparède & Lachmann, 1859) Cockerell, 1911
Diagnosis: Test clear, yellow to brown, dish-shaped, flexible. Test finely areolated, chitinoid, flexible and folded at the ventral side. Cell enclosed within a membranous sac which is fixed to the shell at intervals, but lost in empty shells. This membrane closes the shell from the ventral side and forms an aperture for the lobopodia. One vesicular nucleus, small crystals present.
Dimensions: 36-55 µm
Remarks: It is not certain whether the photomicrographs on this page show Microchlamys patella or a Spumochlamys-species. The photograph below shows a granulated pattern in the shell wall. This could be a Microchlamys.
