Taxonomic notes
According to Chiasson et al. (2007: 257), the form taxon Chantransia pygmaea (specimens from the Hawaiian Islands) is unequivocally associated with five taxa, Batrachospermum ambiguum, B. arcuatum, B. atrum, Nemalionopsis tortuosa and Thorea violacea. - (20 Nov 2007) - Wendy Guiry

According to Necchi & Oliveira (2011: 685), nine species are associated with "C. pygmaea", including members of the Batrachospermales (B. antipodites, B. arcuatum, B. involutum, B. helminthosum, Kumano ambigua, K. virgatodecaisneana and Sirodotia suecica) and the Thoreales (Nemalionopsis tortuosa and Thorea hispida). Affinities have also been observed with taxa of higher taxonomic levels of three genera of the Batrachospermales (Batrachospermum, Paralemaneae and Kumanoa). - (27 Jul 2011) - Wendy Guiry

General environment
This is a freshwater species.
