Nomenclatural notes
Substitute name for Coelodiscus Jao 1941, non H. Baillon 1858. - (1 Mar 2007) - Wendy Guiry

Description: Plants globular or lenticular in shape, 1-6 cm in diameter, hollow and pseudoparenchymatous, attached by simple or branched rhizoids. Thallus 2 or 3 layered outer cells small and pyriform or conical, inner cells large and spherical. Cells uninucleate with single parietal chloroplast and several pyrenoids. Asexual reproduction by quadriflagellate zoospores, 4 to 16 produced in each of many slightly modified outer cells. Sexual reproduction unknown. Jaoa grows on stones in running water and endophytically in Cladophora. Reported from China and Europe. It was suggested that J. endophytica is synonymous with Ectochaete endophytica (Moebius) Wille because it possesses hairs.

Verification of data
Users are responsible for verifying the accuracy of information before use, as noted on the website Content page.

Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
