Description:

Portrait of Hyalosphenia. Amoebae of this genus are characterized by homogeneous proteinaceous tests that are smooth and compressed. Epipodia connect the cell body to the interior of the test. Test may have yellowish tinge. With SEM two tiny lateral pores are seen at the widest part of the test. Distinguishable from the relatively smooth Nebela carinata and N. flabellulum by the absence of lateral ridge and greater length than width respectively. From freshwater pond near Boise, Idaho. Phase contrast.
