Abstract
Virus-infected plants of Myriotrichia clavaeformis from the coast of A rgentina are sterile and produce virus particles in later al vesicles homologous to plurilocular sporangia of normal plants. Virions are rel eased into the surrounding sea water and can infect swimming spores of healthy Myriotrichia plants. Virus particles are hexagonal in cross s ection with a diameter of 170-180 nm and have an envelope with an elec tron dense core. Similar viruses are known for several genera in the o rder Ectocarpales. This is the first record of an infectious agent in the order Dictyosiphonales, which contains thalli with more complex ti ssues and life histories.
