Sorry, no etymologies found.
The product of the union of two zygoblasts is termed a _zygospore_.
After a long period of rest, this zygospore allows the whole of its contents to escape as a swarm-spore, which after a time secretes a gelatinous wall, and by division reproduces the sixteen-celled family.
The zygospore thus formed germinates after a long period and forms a new filament of cells.
_I_, development of the zygospore of a black mould,
These free-swimming cells, which apparently are formed only to reunite with each other, are called zoöspores, while the organism which results from their fusion is known as a zygospore.
The zygospore thus formed slowly increases in size, until it in its turn develops a new generation of zoöspores.
In poor environments, members of the genus may also reproduce sexually to create a zygospore that sinks into the sediment at the bottom of the body of water, where it waits to emerge until more propitious circumstances arise.
