Description: Thallus erect, irregularly branched, with revolute apices, developing axes each bearing a membranous monostromatic keel and 2 adjacent rows of alternating simple terete determinate laterals that are pectinately arranged; holdfast discoid. Indeterminate axes ecorticate, with 6 pericentral cells (dorsal and ventral and with 2 lateral ones on each side); dorsal cells forming the keel and the 2 ventral lateral cells forming the determinate laterals from alternate segments. Indeterminate branches arising endogenously adjacent to the keel. Trichoblasts adaxial from each segment of the determinate laterals. Gametophytes dioecious. Spermatangial organs replacing trichoblasts, flat or triradiate, with sterile marginal cells. Procarps in series on the second trichoblast cell on the next to basal segment of determinate laterals; carposporophytes with terminal carposporangia; cystocarps ovoid ; pericarp corticated. Tetrasporangia in long series in the axes or in proliferous branch clusters, cut off from the lateral pericentral cells opposite to those bearing a determinate lateral, large and covered by a layer of corticating cells [after Womersley (2003: 325)].

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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