Maullinia
Maullinia is a genus of intracellular, protistan parasites that infect brown algae (Phaeophyceae). Distribution. "Maullinia" has been found in brown macroalgae across the Southern Hemisphere, including Chile, the Falkland Islands, Australia, New Zealand and various sub-Antarctic islands. Based on genetic evidence, "Maullinia" have likely been dispersed widely via transport inside of buoyant rafts of southern bull kelp. Description. "Maullinia" infections have been found in filamentous brown algae such "Ectocarpus siliculosus" and "Acinetospora", as well as in macroalgae including "Macrocystis", "Desmarestia", southern bull-kelp. "Maullinia" can cause yellow galls to develop ( in diameter).
