Cryptochrysis fulva   Butcher  (Algae)
Organism information awaits expert curation
Class: Cryptophyceae
Order:Cryptophyceae incertae sedis

Size: Cells are 6-8x3-4 microns.

Cells are actively motile naked with an ovoid appearance in the dorsal view. Apex truncate with slight flattering on the ventral side. Towards the base the cells tapers. From the flattened ventral side, just behind the apex starts a vertical furow which runs down to the region of the pyrenoid. Trychocysts are noticed on the sides of the furrow. From the base of the furrow emerge two unequal flagellate, which are shorter than the cell. Chromatophore single, large, folded and brownish in color, pyrenoid single, large, globular and basal in position. In older cells, two pyrenoids are observed and are placed in either end of the cell. Oil granules similar to the size of the pyrenoids are noticed but not in all. Contractile vacuole present.

Reproduction by longitudinal division of the mother cell in both motile and resting state. Palmelloid stages seen occasionally in cultures. During this stage cells loose their flagellate, become round in shape and the contents turn dark brown in color. Inside these cells division of the chromatophores and other cell contents take place.
