Description: Thallus purple-red (0.22.5 cm), repent, forming entangled mats on upper intertidal rocks; holdfast attached to the substrate by brush-like rhizoidal haptera; uprights mostly absent; decumbent axes terete to slightly compressed, irregularly to subdistichously branched; lateral branches arising at almost right angles. Uniaxial structure with a more or less conspicuous dome-shaped apical cell; cortex consisting of 24 layers of ovoid pigmented cells; medulla consisting of both longitudinal filaments of elongated cells and unicellular rhizoidal filaments with thickened walls, secondarily formed from the innermost cortical and medullary cells. Life history triphasic with isomorphic generations; gametophytes dioecious. Spermatangia in compressed with roundish apices. Cystocarps spherical to ovoid on the apical parts of axes and branches, bilocular, with one ostiole on each surface of the branch; carposporangia elongated, terminal.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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