Callophyllis cristata (sometimes designated as Euthora cristata)
Euthora = L. eu: good, well + thore:
sperm- i.e. “well seeded”
cristata = L.: having
a crest or plume
Common name=
lacy red weed

Algae are bushy, 3-6 (-13) cm tall,
soft but cartilaginous, pink, bright crimson, or brownish red, freely
branched, and with one or more fronds attached by a small disc. Fronds compressed
below and flattened above, repeatedly alternate to almost pinnately
or subdichotomously branched
above. Segments are successively
smaller, narrower, and dense above, with rounded angles, spreading, and with
linear terminal parts that are deeply cut at tips. Medulla is multiaxial,
cortex composed of 1 (-2) cell layers. Tetraspores
irregularly cruciate. Gametophytes dioecious

In Chile,
the demand of edible seaweeds has increased during recent years and Callophyllis variegata
is one of the most demanded species. This study summarizes information on phenology, aspects, in vitro culture and vegetative
propagation methods for Callophyllis.
Results indicate that spore production occurs mainly during winter, and
recruitment of new plants appears in nature in the spring (Hernandez et al.
2002).

The
antioxidant properties of the red seaweed Callophyllis
japonica were investigated. An ethanol extract isolated from C.
japonica exhibited intracellular reactive oxygen species, 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging
activity and lipid peroxidation inhibitory
activity. The radical scavenging activity of the extract protected the
viability of Chinese hamster lung fibroblast (V79-4) cells exposed to H2O2.
These findings suggest that C. japonica exhibits antioxidant
properties (Kang etal, 2005).

In the Northwest Atlantic the alga is
uncommon to locally common; it is a perennial taxon
that is epiphytic on larger algae, as well as occurring on rocks, sponges,
and hydroids. Found in deep lower tide pools and to 40 m.
