Spumella (spew-mell-a), a heterotrophic stramenopile also referred to as Monas. With one long flagellum and one short flagellum which flops over the body. The long flagellum has hairs (not visible with the light microscope), but the presence of which causes fluid to be drawn towards the cell. The current carries particles of food which can be ingested after they make contact with the surface of the cell. Phase contrast.

Spumella (spew-mell-a) (Monas) (moan-ass) the archetypical colourless chrysophyte (stramenopile), almost certainly secondarily without plastid. With typical long and short flagellum, posterior inclusion is leucosin storage granule. This rounded form is common in stressed cells. Phase contrast.

Spumella (spew-mell-a) (Monas) (moan-ass) the archetypical colourless chrysophyte (stramenopile), almost certainly secondarily without plastid. With typical long and short flagellum, posterior inclusion is leucosin storage granule. This is a very typical shape for small chrysophytes. Phase contrast.

Spumella (spume-ell-a) (=Monas) a colourless chrysophyte cell, with two flagella, only one of which is visible here. The flagellum beats with an undulating beat, and water is drawn towards the top of the cell. These organisms usually consume suspended bacteria. Phase contrast. Material from Nymph Creek and Nymph Lake, thermal sites within Yellowstone National Park, photograph by Kathy Sheehan and David Patterson.

Spumella (spew-mell-a) (Monas) (moan-ass)
-
Spumella, a colorless chrysophyte flagellate. Cells are solitary and may be free-swimming or attached to subratum by drawn out posterior as seen here. The cell body is pyriform and truncate anteriorly with two unequal length flagella (the longer with tripartite hairs visible only by electron-microscopy, the short one smooth). Cells are phagotrophic. One or more contractile vacuoles. From temporary rainwater pool in grass field near Boise, Idaho. Phase contrast.

The cell on the left is very distressed, but is included to show the distinctive long and short flagella of the true chrysophytes. Phase contrast micrograph.

Spumella (Monas) uniguttata Skuja, 1939. Cells 7-12 microns long and 4.5-6 microns wide, metabolic, variable in shape. Cells obovate to oval, anteriorly oblique-truncated and posteriorly rounded, or round to cylindrical in a amoeboid form. Longer flagellum about 2-3 times cell length and short flagellum 1/2-1/3 times cell length. Cytoplasm hyaline. Contractile vacuole in the anterior part and nucleus in the centre.
