• "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."
