Description: Thallose; thallus composed of free, separated, initially creeping filaments and later erect branches; filaments more or less densely parallel situated forming Symploca-like fascicles. Trichomes uniseriate, only rarely with cells dividing lengthwise and laterally branched (V- and T-type). Cells barrel-shaped (forming torulous trichomes) in old filaments with thickened, usually brownish sheaths, young trichomes and branches with cylindrical cells, with thin, colorless sheaths. Heterocytes intercalary, rarely lateral. Akinetes missing. Reproduction by 8-10-celled hormocysts, which separate at the ends of branches. Sheaths of hormocysts thick, usually brownish. Hormogonia not known. Aerophytic, known mainly from flower-pots in glasshouses.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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