| ABSTRACT |
|
Two unrecorded species of Sphacelaria from Korea are investigated taxonomically. Sphacelaria fusca Agardh is characterized b its filamentous thallus, irregular branches with longitudinal divisions mixed with secondary transverse divisions in segments, cylindrical propagula with (2)-3-(4) arms, spherical unilocular sporangia with one pedicellate cell and ellipsoidal plurilocular sporangia. Judging from field phenology, the propagula formation is independent upon temperature and photoperiod, while the sporangium formation seems to be dependent on lower temperature. Sphacelaria californica Sauvageau is characterized by its filamentous thallus, opposite to pinnate branches with longitudinal divisions mixed with secondary transverse divisions in segments and tribuliform propagula. The lateral end cells of the propagula arms divide into two, which is another character differing from S. plumula.
