Status of name
This name is of an entity that is currently accepted taxonomically.
No synonyms are currently included in AlgaeBase.
The alga has spherical solitary cells, migrating cells, heliozoan-like cells, and zoospores as well as meroplasmodia with two forms of sessile cells. The main bodies of the meroplasmodial cells are about 15 microns in diameter. They have walls with fine pores and are connected by reticulopodia. The form of these cells is either spherical or kidney- to bulb-shaped with concave depressions. Solitary spherical cells have walls of about 0.15-0.35 microns thick, without lamellae. The vegetative reproduction of the sessile cells of the meroplasmodium takes place by binary fission. One of the daughter cells remains sessile, whereas the second cells is transformed into a migrating amoeboid cell which generally moves in the strands of the reticulopodia. Spherical solitary cells occasionally show budding or binary division. Zoospores are spindle-shaped, wrapped by one twisted and subapically inserted flagellum. Gametes are unknown. The bilobate chloroplasts have one pyrenoid, which is directed to the centre of the cell. The length of the bulbous pyrenoid is about 0.9 microns; the pyrenoid has a longitudinal incision and a capping vesicle with no internal structure. The nucleomorph is located laterally at the base of the pyrenoid in a peripastidial compartment.
