General Environment
This is a marine species.
Description
Thallus leafy, lamelliform, irregularly roundish in shape; roof of mature tetra/bisporangial conceptacles, moundlike to flush with the surface; cells bordering the tetra/bisporangial conceptacle pore canal similar in size and shape to the other roof cells within the pore plate; rosette cells similar to surrounding roof cells; gametophytic thalli monoecious to dioecious; tetra/bisporangial conceptacles confluent, not becoming buried in the thallus, but shed on senescence, often leaving shallow craters on the surface
Habitat
Synarthrophyton chejuensis is most abundant along the south coast of Korea at sites exposed to moderate wave action. Here, it forms conspicuous reddish purple to pinkish red (in the water) leafy thalli that grow on geniculate coralline algae, other algae or rocks and shells, between 5 and 15 m deep. Reproductive materials were found from February to June but there are no collections in other months. At sites along Cheju Island, the alga was usually attached to Amphiroa anceps, C. pilulifera and M. crassissimum, whereas at sites off the south-eastern coast of Korea it was often epiphytic on Alatocladia modesta or G. amansii
