Life History:
-
alternation of heteromorphic phases. Isolates from Sweden and Newfoundland had a macroscopic sporophyte with unilocular organs which bore zoospores which germinated to form dioecious microscopic filaments with plurilocular gametangia. Zygotes and unfused isogametes gave rise to filamentous protonemas from which grew macroscopic plants similar to field sporophytes ( Saga 1986; Peters and M & uuml; ller 1985; Arasaki 1949 )
