Description: Plants reach 20 cm in length and are erect from a discoid base. Fronds are flattened above, and irregularly branched. The medulla is densely crowded with large medullary cells and interspersed thin rhizoids, and is surrounded by a deep pseudoparenchymatus cortex. Cystocarps have a large fusion cell surrounded by dense clusters of gonimoblasts, and are characterized externally by a thorn-like projection that probably represents the apex of the fertile determinate lateral branch. Procarps and all stages of gonimoblast development are not well documented, and both male and tetrasporangial plants are unknown.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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