Pyropia

Pyropia is a genus of red algae in the family Bangiaceae. It is found around the world in intertidal zones and shallow water. The genus has folding frond-like blades which are either red, brown or green. Some Pyropia species are used to create nori, and are thus important subjects for aquaculture.

==Taxonomy== Pyropia was originally erected by Jacob Georg Agardh, a botanist and professor at Lund University. Before this, and sometimes after, many species of Pyropia were placed in Porphyra, a different genus of red alga. New species of Pyropia are still being discovered, for example in 2013 research done on New Zealand plants was able to move Pyropia plicata from Porphyra.
