9 Hydrolithon breviclavium Waianae coast at artificial reef Surge current. Bottom: smooth dead coral rock with pockets of sand and melobesioid covered, dead coral rubble. Preserved_Specimen Thallus deep red with small unbranched small excrescences. This form is very common and completely surrounds its substrate. Littler, M.M. 423 Oahu BISH 1968-03-07
10 Hydrolithon breviclavium Maile, Reef 2 m seaward of Very abundantly scattered about as aggregates in direct sunlight and often piled several layers deep in pockets. Preserved_Specimen Red in color and composed of highly branched and fused excrescenses. Littler, M.M. 531 Oahu BISH 1968-09-27
11 Hydrolithon breviclavium Makua, 300 m seaward of the beach A volcanic lava flow covered by coelenterate corals and melobesioids. No current and moderate surge. Preserved_Specimen Scattered about as aggregates on the lava flow. Small knobby excrescences and pale maroon in color. Littler, M.M. 514 Oahu BISH 1968-09-22
12 Hydrolithon breviclavium 1 mile off Maile On dead reef. Preserved_Specimen Forming crusts and aggregates. The crusts appear purple at depth. This is the most abundant species in the area of the mound. Small excrescences are present. Littler, M.M. 576 Oahu BISH 1969-02-13
13 Hydrolithon breviclavium Maili, 1 mile seaward Growing on dead coral. Turbid water and moderate surge. Dominant species in the area. Preserved_Specimen Appears deep purple at depth but is a maroon red with convex concepts. Appears similar to Melobesioid C. Forms aggregates but also covers large expanses of the relatively smooth sea floor. Littler, M.M. 544 Oahu BISH 1968-10-24
14 Hydrolithon breviclavium Mound 1 mile off Maile Substrate is dead coral. Water was moderately turbid. Coverage of the hard bottom was mainly by Symploca sp and Herposiphonia sp which trap sand. Preserved_Specimen Growing as crusts and free aggregates. Branched knob-like excrescences. This alga appears deep purple at depth but is pink in white light. This is the dominant alga in the area. Occasional lateral fusions are present. Littler, M.M. 555 Oahu BISH 1968-11-21
