The Floride^ are red or violet-coloured seaweeds, the greencolour of their chlorophyll-grains being concealed by a red;pigmentwhich can be extracted by cold fresh water. They are propagated[sexually] by means of oospores formed in capsular fruit-like cells, thecystocarps (see Fig. 386, p. 253), and [asexually] by tetraspores (, p. 251), produced in fours in special cells. The CEDOGONiEi^i, to which allusion has already been made, differso greatly from other Algae in the processes which accompany theirreproduction, that they cannot be included in any of the classes alreadynamed, but form a distinct one by themselves (see Fig. 385, p. 252). The SCHIZOMYCETES form a kind of supplementary class ; a groupof small organisms so near the extreme boundary of visibility that thesepar
