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]
