The zygospores have very thick walls and the small, spherical inclusions are oil droplets (reserve food supply). These thick-walled spores can survive for prolonged periods (weeks - months- years) but eventually germinate to produce spores that will infect a later generation of the host. In the meantime, of course, they could be attacked and consumed by some other predator of 'thick-walled' spores like the giant mycophagous amoeba Vampyrella.
