Description: Thallus filamentous, loosely branched, composed of long cylindrical cells. Filaments usually tapered towards the tips, repeatedly branched. Later, the cells form multiseriate filaments composed by swollen, rounded, loosely connected cells. These filaments easily disintegrate into single cells. Chloroplast reticular, with indistinct pyrenoid. Asexual reproduction by thallus fragmentation into cell packets or single cells which become thick-walled akinetes. No zoospores were observed. Sexual reproduction unknown.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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