Description: Thallus epiphytic, with limited to extensive prostrate axes and assurgent alternately to subdichotomously branched erect axes, attached to the host by unicellular rhizoids arising from periaxial cells. Axes filamentous, with nodal cortication; apices straight to forcipate. Nodes with 3–9 periaxial cells (some species with additional pseudoperiaxial cells), each with 3 or 4 corticating filaments; basipetal cortical initial single, transversely elongate. Spermatangia produced from cortical cells. Cystocarps near the apices, surrounded by involucral branches. Tetrasporangia generally in whorls on nodes, 1 per periaxial cell, involucrate, tetrahedrally divided.

Verification of Data
Users are responsible for verifying the accuracy of information before use, as noted on the website Content page.

Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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