Overview
Comprehensive Description
Description
The sexual (gametophyte) plant is delicate, up to 30 cm tall, with barbed branches and is rosy pink, yellowish-pink or whitish-pink in colour. The thallus has prominent major axes, bare in lower parts but densely tufted above. The plant is attached to other algae by barbed rhizoids. The asexual (tetrasporophyte) plant is a rose-pink in colour, and is formed of irregularly-branched, polysiphonous axes that are usually aggregated into spherical or hemispherical masses 1-3 cm in diameter.The asexual (tetrasporangial) phase of Asparagopsis armata was once described as a separate species, Falkenbergia rufolanosa. The alga is a non-native species first recorded in Ireland in Galway Bay in 1939 and Britain in 1949 at Lundy in the Bristol Channel.

Description
The gametangial plant grows to 30 cms long and is attached by barbed rhizoids to other algae. Thallus with tufts of branchlets all about the same length and spirally arranged. The tetrasporic phase (=Falkenbergia) is of small fine filaments irregularly branched which aggregrate into small fluffy balls.

The sexual (gametophyte) plant is found in the shallow sublittoral or in deep littoral pools attached to other algae by its barbed axes. The asexual (tetrasporophyte) plant is typically found sublittorally and is epiphytic or sometimes free-living.

Asparagopsis armata
Asparagopsis armata is a red algae situated mostly in deep areas.
In the Azores Archipelago, this algae measures up to 15 cm and compromises a total of many abundance in local submerged parts, it has a boundary with the sea and is located in the Atlantic.
The cycle or life are in two phases of distinct morphology. It is identified in two different species than the same under the scientific names (Falkenbergia rufolanosa (Harvey) F.Schmitz).
These gametophyte algae occurs between June and July as well as August and September, it conforms to its water distribution. It provides the coloring with red. It has some cylindrical of around 1 mm in length and around 200 mm (20 cm) in width.
