Description of Anthophysa vegetans
provided by BioPedia
Cells are wide at the anterior and at one side of the anterior end is a site where food is taken in, and the two flagella (one longer one shorter) insert to the side of this. The posterior tip of the cell extendS into a fine protoplasmic filament of variable length and many cells are usually united at their bases into spherical or hemispherical colonies, and these may either be free-swimming or attached to the substrate by means of a stalk which is coloured brown and is often branched. The stalk nearest the cells is usually narrower and transparent, becoming thickened distally by the deposition of iron and manganese compounds; bacteria are embedded in it throughout its length and can be seen clearly close to the colony.
