Description: Thalli microscopic, forming erect, dichotomously branched pseudofilaments. Cells surrounded by a thick mucilaginous sheath. Pseudofilaments uniseriate initially, becoming pleuriseriate except at the distal end and the basal region. Each cell containing several parietal, disk-shaped chloroplasts lacking pyrenoids. Contains B-Type II phycoerythrin. Pit plugs absent. Growth intercalary or diffuse, except in very early stages of development following spore germination when growth may be apical. Attached to the substratum by basal cells lacking rhizoids. Asexual reproduction by archeospores; entire vegetative cells transformed into archeosporangia with each releasing a single, wall-less archeospore. 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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
