Description: In habit, epi/endozoic within invertebrates. Uniseriate erect and basal systems, erect filaments free, basal filaments endozoic, forming a tortuous network of filaments of varying compactness. Direct life history by asexual tetrasporangia. Tetrasporangia terminal or lateral on erect filaments, cruciately divided, frequently with an apical lens, discoidal and slightly elongated plastids. Plastids of vegetative cells diffuse parietal bands, or more distinctly lobed, to spiraled in cells towards the apices of erect and basal filaments; pyrenoids absent. B-phycoerythrin.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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