Abstract:Five new species are described: one in the brown algal genus
Padina and four in the red algal genera Hypoglossum, Spirocladia, Micropeuce,
and Laurencia. Padina melemele Abbott & Magruder differs from known Padina
species because of extremely strong calcification on the ventral surface and
a bright yellow color on the dorsal surface. Hypoglossum wynnei Abbott differs
from other species of Hypoglossum in Hawai'i in having divided, ribbonlike
segments and small, discrete sporangial sori. Spirocladia hodgsoniae Abbott
shows distinctive holdfasts where proliferation of cortical cells connects decumbentaxes
and erect filaments. Micropeuce setosus Abbott is a minute species
collected at 72 m depth, showing conspicuous bristlelike trichoblasts on
each tetrasporangial segment. Laurencia mcdermidiae Abbott joins a number of
species of Laurencia marked by their bright green color, ordinarily pink or red
in other species. Dudresnaya littleri Abbott is proposed as a new name for D.
lubrica Littler [non D. lubrica (Lyngbye) Trevisan], and taxonomic notes are
given on Trichogloea species. Halymenia maculata J. Agardh, Predaea laciniosa
Kraft, Cubiculosporum koronicarpis Kraft, and Kallymenia sessilis Okamura are
given as new records.
