Erythrotrichia carnea   (Dillwyn) J. Agardh,  1883 (Algae)
Organism information awaits expert curation
Class: Compsopogonophyceae

Image copyrights: Seaweed database

Color: Red

Plants upto 0.5 µm long, simple filamentous, filaments at the basal part slender, 6-13 µm wide, upper parts broader, 15-26 µm wide, chloroplast stellate with a pyrenoid, monosporangia formed by oblique walls.
Red color 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).

Epiphytic on various algae (e.g. Porphyra, Polyides, Dictyota, Padina) and on eelgrass Zostera.
