Taxonomic notes
According to Grant et al. (2013: 62), the type species of Olisthodiscus, O. luteus Carter was found to be conspecific with Heterosigma akashiwo (Hada) Hada ex Hara & Chihara (Hara & Chihara 1987), as was O. carterae (Hallegraeff & Hara 2003). They also note that Yamaguchi et al. (2008) have suggested that Olisthodiscus may not belong in the Raphidiophyceae. - (04 March 2013) - G.M. Guiry
"Another thing I noticed in the list, you have Olisthodiscus luteus as a synonym of Heterosigma. That is what people believed from 1969 to 1983 when true Olistodiscus luteus was found in Japan (I think it was reported for the first time in the abstracts from the first phycological congress in Newfoundland). We also found it in Denmark and have both Heterosigma akashiwo and Olisthidiscus luteus in SCCAP. They are very different and actually belong to different classes but forget about that for moment, it has not been published yet! Just include Nellie Carter's nice species Olisthodiscus luteus in the Raphidophycae. It is a beautiful flat species (just as she described it) which swims along the bottom like a ray (without rotating), while Haterosigma akashiwo is a planktonic species which rotates all the time. It is barely flattened." Ø. Moestrup, e-mail 18 November 2013.

Contributors
Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera,
organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA)
and intended to be published in CD format.
These AlgaeBase descriptions are now being continually updated, and each current contributor is identified above.
The PSA and AlgaeBase warmly acknowledge the generosity of all past and present contributors and particularly the work of Dr Parker.
Descriptions of chrysophyte genera were subsequently published in J. Kristiansen & H.R. Preisig (eds.). 2001. Encyclopedia of Chrysophyte Genera. Bibliotheca Phycologica 110: 1-260.
