Abstract: Gloiotrichus fractalis Huisman & Kraft is documented for the first time
from the island of Hawai'i, Hawaiian Islands, which also represents the first
record for the Pacific Ocean. The single specimen on which the record is based
is 12 cm in height, extremely mucilaginous, with percurrent primary axes and
irregularly arranged lateral branches. Carpogonial branches are borne on the
basal one to three cells of cortical fascicles; when mature they are five to eight
cells long and straight. Before fertilization, cells of the carpogonial branch produce
several lateral branches similar in morphology to cortical filaments. After
presumed fertilization the zygote (= postfertilization carpogonium) divides
transversely and gonimoblast initials are produced from both of the resultant
cells. Mature carposporophytes are spherical, with terminal carposporangia and
a fusion cell formed from the cells of the carpogonial branch and basal cells of
lateral filaments. The Hawaiian specimen is identical in virtually all respects to
those from the Indian Ocean type locality in the Houtman Abrolhos Islands of
Western Australia.
