Dorsal silverline system (argyrome) of the oligohymenophorean ciliate, Lembadion lucens (Maskell, 1887) Kahl, 1931. There are 25-35 evenly spaced longitudinal somatic kineties. The posterior 2/3 of the pellicle of L. lucens has an areolate pattern divided into small roughly rectangular depressions (similar to the pattern of the entire pellicle of L. bullinum). The dikinetids of the somatic kineties occupy the center of the rectangles. The anterior 1/3 of the pellicle has a longitudinal striate pattern (similar to the pattern of the entire pellicle of L. magnum). The somatic dikinetids lie in the center of these striae. This specimen is stained by the silver carbonate technic (see Foissner, W. Europ. J. Protistol., 27:313-330;1991). This technic usually demonstrates the infraciliature which includes kinetodesmal fibrils and other structures not considered part of the silverline system but in this instance the silveline system and somatic dikinetids are stained. L.lucens is distinguished from L. magnum and L. bullinum by its smaller size and the structure of its pellicle. Specimen collected from a freshwater pond near Boise, Idaho 2005.Brightfield.

Portrait (dorsal view) of the oligohymenophorean ciliate, Lembadion lucens (Maskell, 1887) Kahl, 1931 showing detail of the pellicle. The cell outline is oval. The ventral surface is concave and the dorsum convex. The very large scoop-like peristome occupies most of the ventral surface. The cytostome is at the posterior end of the peristome. There is a small undulating membrane on the right margin of the peristome. A large sheet-like adoral membranelle arises from the left margin of the peristome. There are 25-35 evenly spaced longitudinal somatic kineties. The posterior 2/3 of the pellicle of L. lucens has an areolate pattern divided into small roughly rectangular depressions (similar to the pattern of the entire pellicle of L. bullinum). The dikinetids of the somatic kineties occupy the center of the rectangles. The anterior 1/3 of the pellicle has a longitudinal striate pattern (similar to the pattern of the entire pellicle of L. magnum). The somatic dikinetids lie in the center of these striae. Ingested diatoms and highly refractile crystals are visible in the cytoplasm. Collected from a freshwater pond near Boise, Idaho July 2004. DIC .

There is usually a tuft of longer caudal cilia. The contractile vacuole (seen here to the viewer’s right of the macronucleus) connects with its excretory pore by a long curved canal (not seen here). The single ovoid macronucleus and micronucleus are posterior (the micronucleus is seen overlying the macronucleus here). Ingested diatoms and highly refractile crystalline inclusions are visible in the cytoplasm. L. lucens is distinguished from L. magnum and L. bullinum by its smaller size and the structure of its pellicle.Collected from a freshwater pond near Boise, Idaho July 2004. DIC .

The very large scoop-like peristome occupies most of the ventral surface. The cytostome is at the posterior end of the peristome. There is a small undulating membrane on the right margin of the peristome (pink arrowhead). A large sheet-like adoral membranelle arises from the left margin of the peristome (green arrowhead). There are 25-35 evenly spaced longitudinal somatic kineties (yellow arrowhead). The posterior 2/3 of the pellicle of L. lucens has an areolate pattern divided into small roughly rectangular depressions (similar to the pattern of the entire pellicle of L. bullinum).

The ventral surface is concave and the dorsum convex. The very large scoop-like peristome occupies most of the ventral surface. The cytostome is at the posterior end of the peristome. There is a small undulating membrane on the right margin of the peristome (pink arrowhead). There is a densely impregnated longitudinal line of fibrils running the length of the peristome parallel to the undulating membrane (light blue arrowhead). A system of fine transverse fibrils lines the floor of the peristome. A large sheet-like adoral membranelle arises from the left margin of the peristome (green arrowhead). There are 25-35 evenly spaced longitudinal somatic kineties (red arrowhead). The posterior 2/3 of the pellicle of L. lucens has an areolate pattern divided into small roughly rectangular depressions (similar to the pattern of the entire pellicle of L. bullinum). The dikinetids of the somatic kineties occupy the center of the rectangles. The anterior 1/3 of the pellicle has a longitudinal striate pattern (similar to the pattern of the entire pellicle of L. magnum). The somatic dikinetids lie in the center of these striae. There is usually a tuft of longer caudal cilia. The closely-spaced kinetosomes from which these cilia arise are indicated by the dark blue arrowhead. The contractile vacuole connects with its excretory pore by a long curved canal. The single ovoid macronucleus and micronucleus are posterior. L. lucens is distinguished from L. magnum and L. bullinum by its smaller size and the structure of its pellicle. Stained by the silver carbonate technique (see Foissner, W.Europ. J.

Ventral infraciliature of the oligohymenophorean ciliate, Lembadion lucens (Maskell, 1887) Kahl, 1931. The very large oral aperture (OA) is bordered on the left by a vast undulating membrane, the densely stained base of which is seen here (AOM). The kinetids of the elongated caudal cilia form a line at the posterior pole (CC).There are 25-35 evenly spaced longitudinal somatic kineties. The posterior 2/3 of the pellicle of L. lucens has an areolate pattern divided into small roughly rectangular depressions (similar to the pattern of the entire pellicle of L. bullinum).
