Porphyra's life history has been studied intensely throughout time, especially because of its high economic value. Originally, it was thought that Porphyra had a single life history stage, however, in 1949, Kathleen Drew-Baker discovered that the alga Conchocelis rosea was actually a stage in the life history of Porphyra! Therefore, Porphyra has a trimorphic life history, with a thallus stage, carposporophyte stage and a filamentous Conchocelis phase, as shown below.
