Myxosporean spores of genera belonging to the Myxobolidae are flattened parallel to the
sutural line. They typically contain two
polar capsules, and have a central vacuole in which they store
β-glycogen. In some genera, the spore walls are drawn out into long processes which are thought to slow sinking through the water column.[citation needed]
Actinosporean stages which have been linked to members of the Myxobolidae have a single central "style" and three processes or "tails", around 200 micrometers long, projecting from this. A
sporoplasm packet at the end of the style contains 64
germ cells surrounded by a cellular envelope. There are also three polar capsules, each of which contains a coiled
polar filament.[citation needed]
