After the production of this oospore the parent filament gradually loses its vitality and slowly decays.
This oospore, or resting spore, may remain dormant in this state within the tissues of the foster plant for some months.
The oospore becomes an oosporangium, and from it at least a hundred germinating bodies are at length expelled.
Reproduction from an oospore formed by the combination of two sexual cells.
The oospore on germination usually gives origin to a zoosporangium, but may form directly a germ tube which infects the host.
The product of the union of an antherozoid and an oosphere is termed an oospore.
