Chroomonadaceae

Chroomonadaceae is a family of cryptomonads first recognized by Clay et al in 1999 as including genera Chroomonas, Falcomonas, and Komma.[1] Following a molecular phylogenic study in 2002, Hemiselmis was also placed within the Chroomonadaceae.[2] Today, the family is generally recognized as sister to the Pyrenomonadaceae.

They are one of only two groups of cryptomonads (alongside Rhinomonas) to lack a rhizostyle. They are also distinguished by the lack of a cleavage furrow and the presence of several phycocyanins and phycoerythrins not observed in any other cryptomonad taxa.[3]
