Descripción

Collected at 3:50PM, this species was located at the waterline at the mid intertidal zone loosely situated on top of a rock. Ulva and other abundance of green algae were found nearby. There are whorled branching patterns with each whorl consisting of three to four (sometimes two) determinate branches of unequal length. Gland cells are also found at the terminal of the cells of the determinate branches. It was the only Hollenbergia subulata present in this area, appearing to be scarce. Reproductive structures, tetraspores, are found on the branches of this species.
