Scinaiaceae

Scinaiaceae is a family of red algae (Rhodophyta) in the order Nemaliales.^[2][3]

Scinaiaceae
Scinaia furcellata
Scientific classification
Clade:	Archaeplastida
Division:	Rhodophyta
Class:	Florideophyceae
Order:	Nemaliales
Suborder:	Galaxaurineae
Family:	Scinaiaceae J.M. Huisman, J.T. Harper & G.W. Saunders 2004[1]
Genera
See text

Huisman had placed former members of Galaxauraceae family, that were lacking lime into his new family of Scinaiaceae.^[4]

Distribution

The family has cosmopolitan distribution.^[5] Including being found in India,^[6][7] Arabian Sea,^[8] Brazil,^[9] North America (including Alaska, British Columbia, Washington, and Oregon^[10]) Chile, New Zealand (Tasmania and Campbell Island) and the Falkland Islands.^[3]

Notes

Molecular analyses of DNA on species of Nothogenia has been carried out to determine species relationships.^[3]

Most Scinaiaceae species produce mucilage (thick, gluey substance) mainly in the cortical layer.^[11]

Several species in the Scinaiaceae family (including Nothogenia fastigiata and Scinaia hatei) have been screened for anti-viral activity (against herpes, Respiratory syncytial virus (RSV), Influenzavirus A, Influenzavirus B and simian immunodeficiency viruses). Sulfated polysaccharides (xylomannans) from the red alga, have inhibitory effects.^[12][13]

List of genera

According to the AlgaeBase (amount of species per genus);^[14]

• Gloiophloea J.Agardh - 3 spp.
• Nothogenia Montagne^[3] - 10 spp.
• Scinaia Bivona-Bernardi - 45 spp.
• Whidbeyella Setchell & N.L.Gardner - 1 sp. Whidbeyella cartilaginea^[15]

Former genera; Ginannia Montagne, Haloderma Ruprecht, Myelomium Kützing, Pseudogloiophloea Levring and Rhodosaccion (J.Agardh) Montagne.^[14]
