Description: Thallus (gametophyte) erect, with a proliferous stoloniferous base giving rise to several percurrent primary axes that are densely clothed with fine lateral determinate branches (giving the appearance of ‘foxtails’), the density of branching increasing towards the apex. Structure uniaxial, with 3 periaxial cells per axial cell, ecorticate in lateral determinate branches but corticate in primary axes. Spermatangia on short clavate branches. Cystocarps obvious, pedicellate. Tetrasporangial phase (‘Falkenbergia’ stage) diminutive, tufted, uniaxial with 3 periaxial cells, ecorticate. Tetrasporangia cruciately divided. Life history triphasic, with a heteromorphic gametophyte and tetrasporophytes.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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