Description: Plants cultured on agar consist of two types of filament long-celled filaments penetrate surface and grow horizontally; surface filaments erect, short-celled and often multiseriate. Cells uninucleate with parietal chloroplast and one to several pyrenoids. Zoospores and gametes produced in globose cells of erect system, zoospores biflagellate or quadriflagellate and gametes isogamous and biflagellate. Some cells of erect system produce haematochrome and become akinetes. Nayalia grows on the surface of desert soil in Egypt. This genus closely resembles Fritschiella.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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