Abstract: | A hemiparasitic alga, Sorellocotax stellaris sp. nov. is described growing on plants of Sorella repens collected from Onagawa, Miyagi Prefecture, east coast of Honshu, Japan. The thallus is small, up to 2 mm high, once or twice branched from the margin. The growing apex has a transversely dividing apical cell, and intercalary cell divisions occur in the cells of first-order rows. Tetrasporangia are cut off from the cells of the inner cortex, The procarp is composed of a supporting cell, one group of sterile cells and two carpogonial branches. Carposporangia are borne in short chains. |
