LSID urn:lsid:algaebase.org:taxname:77373 [details]Unreviewed
Diet photosynthetic [details]Dimensions up to 20 cm high [details]
Distribution Long Island Sound to Strait of Belle Isle [details]
Habitat low littoral, tide pools and shallow sublittoral to 10 m growing on stone or as an epiphyte on diverse algae [details]
Morphology 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. [details]
Reproduction 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) [details]
