Pyrenomonas is a genus of nomen nudum cryptomonad.1 It is a red alga with a bilobed chloroplast and a central pyrenoid, which has an invagination that houses a nucleomorph.2

Pyrenomonas salina, the type species, was characterized in 19843 but has since been renamed to Rhodomonas salina.4 According to AlgaeBase, Pyrenomonas would only encompass two recognized species: Pyrenomonas helgolandii U.Santore and Pyrenomonas ovalis P.Kugrens, B.L.Clay & R.E.Lee, 1999.5 The following species are considered synonyms of the accepted names:
