Fructification: by zoospores, either single or very numerous, and by resting spores formed in sporangial cells after the contents have been impregnated by the contents of autheridial cells of different forms.

Reproduction by zoospores formed of the whole contents of a cell, with a crown of numerous cilia; resting spores formed in sporangial cells after fecundation by ciliated spermatozoids formed in antheridial cells.

Some of the cells enlarged, and then forming either vesicular empty cells or densely filled sporangial cells.

The close compression of the spores within the sporangium leads to a complete fusion of the encysting wall of each one with those of the others which it touches and with the sporangial wall.

Zodspores escaping each by a separate perforation of the sporangial wall, leaving a ** net. "
