Gelidium pusillum   (Stackhouse) Le Jolis,  1863 (Algae)
Organism information awaits expert curation
Taxonomy
Kingdom:Plantae
Phylum:Rhodophyta
Class: Florideophyceae
Order:Gelidiales
Family:Gelidiaceae

Description
Color: Dark Red

Thallus form and type: Flattened tufts

Substratum: Intertidal rocks, coralline stones

Occurrence: Upper mid littoral zone, sheltered

Season: November-April

Abundance: Moderate

Plants forming small or large low cushions; firmly attached to the substratum by rhizoids given off from the decumbent branches; fronds seldom more than 1 cm high; some of the ramuli flattened, markedly attenuate at the base, irregularly arranged, apex broad, usually notched; cartilaginous in texture. Red colour results from the dominance of the pigments phycoerythrin and phycocyanin; this masks the other pigments, chlorophyll a (no chlorophyll b), beta-caratene and a number of unique xanthophylls.

Vegetative reproduction is rare; asexual reproduction is effected by the formation of various kinds of spores. Sexual reproduction is unique in this group due to their passive, non flagellated sperm cells (spermatia).
