Abstract:
A new species, Halichrysis corallinarius sp. nov. is
described from coral reef habitats in southwest Puerto
Rico as well as from Grand Cayman Island. The new
species produces strap-shaped thalli supported above
the substrata by abundant peg-like stipes. The lobed
branches are frequently anastomosed with colonies
measuring to 4.0 cm broad with individual axes measuring
to 7.0 mm across. Algae possess up to five layers
of medullary cells with frequent open spaces in the
medulla. Tetrasporangia, measure to 19 x 25 µm, and
are borne in sori limited to ventral surfaces. Gametophytes
are monoecious and hemispherical carposporophytes
are produced dorsally, measuring to 900 µm in
diameter and 600 µm high.
