Grateloupia huanghaiensis H.W.Wang sp.nov.as a new species was discovered by my laboratory in 2010.To supplement information on its life history and confirm its best growth ecological condition, early development of G.huanghaiensis was investigated under different temperature gradient and different illumination.The results were listed as follows:(1)Four physiological stage were recognized by continuous microscopic observation: division stage,filament stage, discoid crust stage and erect thalli stage.At the beginning of the division stage,the carpospores developed germ tubes into which carpospore protoplasm was evacuated and septa was formed between the germ tubes, then the inflated apex of germ tubes began to develop the basal cell.
