Description: Tropical to temperate freshwater algae, sometimes penetrating into slightly brackish waters, forming minute tufts or turfs less than 1.5 cm tall, consisting of erect uniseriate filaments, attached by a coralloid holdfast and/or long secondary rhizoids. Sometimes several filaments arising from the same holdfast, basal cells are short. Thalli densely branched, with lower parts of the thallus frequently sparsely branched. Branches mainly opposite, sometimes pectinate. Insertion of branches subterminally, sometimes serially, at acute angles, with delayed cross wall formation, cross walls steeply inclined. Up to five laterals per cells, frequently forming whirls. Cells typically slightly constricted at nodes. Apical parts frequently long and unbranched. Adventitious rhizoids formed in all parts of the thallus. Cells in main axis 3–6 times as long as broad, cells in branches can be up to 1.5 mm long. Cell shape cylindrical to irregular. Apical cells 20–50 ?m in diameter, branches 20–60 ?m, basal parts up to 130 ?m. Cell walls relatively thin, up to 6 ?m in basal parts, 1 ?m in apical cells. Zoospore formation by transformation of terminal cells into slightly swollen zoidangia. Thalli epizoic on freshwater molluscs or attached to stationary substrates. Morphologically similar to Aegagropila

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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