Description: Solitary cells or groups of cells, joined to the substrate. Cells more or less polarized, attached to the substrate by the gelatinous pad and by rounded base, apical end Å rounded; they are vase-like or clubshaped, narrowed or widened near the base. Around cells firm, sometimes lamellated sheaths, which are later "opened" at the apical end (pseudovaginae). Cell content greyish blue-green, olive-green or pinkish red, finely granular, always without aerotopes. Reproduction by the rapid successive, total division of cells (multiple fission) into more small daughter cells (nanocytes). The first or several first division planes are oriented parallel with the substrate (perpendicular to the vertical axis of the sessile cell). Nonmotile nanocytes escape from the pseudovagina through the apical opening. All cells divide obligately once into small nanocytes, which after joining to the substrate grow again into the original size and shape (before the next division). Little known genus, found only from a few localities. Four species are marine, living attached to the higher littoral algae, two species are freshwater, known from Sphagnum leaves in alpine moors (Switzerland) and from periphyton on algae in a clear lake in Chatham islands (type species).

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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