General Environment
This is a marine species.
Description
Single foliaceous monostromatic thallus,
bright green in nature and becoming dark olive green after
drying. Liberation of zooids from specimens starts with marginal
zone discoloration, disintegration of the zooidangium
wall, and the release of four biflagellate zooids. Zooid
fusions and a Codiolum phase were not observed; therefore,
reproduction is asexual. After zooid release and a
short swimming period, one of the flagella attaches to the
substratum, while the zooid spins a little longer until settling.
After zooid attachment, cell divisions start, giving
rise to a uniseriate filament, which becomes multiseriate
without formation of tubular or saccate stages. A small
foliaceous thallus develops and expands into a monostromatic
plantlet after 30 to 40 days in culture, around 300 µm
broad. The mature thallus size is usually 7 ± 2.6 cm, with
cell size and thallus thickness of about 8 ± 3 µm and about 25 ± 1.8 µm,
respectively. Cells are uninucleate, with a large central
vacuole, parietal chloroplast, and one or two pyrenoids.
