Description: Thalli large, perennial, erect, epilithic, caespitose or non-caespitose, arising from a discoid/ conical holdfast or from prostrate axes with haptera; primary axes cylindrical, simple or branched; primary laterals annual, cylindrical and profusely radially branched; all orders of laterals decreasing in length towards the apex, the majority of species with numerous spine-like appendages; laterals sometimes iridescent, with scattered cryptostomata and inconspicuous aerocysts; tophules present or absent; in section, thallus parenchymatous, comprising a central, well-developed medulla of small polygonal cells, surrounded by a cortex of globose, thin-walled, sometimes deformed, cells within an enclosing, single layered, palisade-like meristoderm comprising cells ellipsoidal to rounded in surface view, pronouncedly rectangular in cross section. Monoecious, receptacles formed at the end of terminal branchlets, with grouped conceptacles and spiny or filiform appendages; conceptacles hermaphrodite, with dark brown oogonia borne around base, large, with a single egg, which upon release may be incubated on receptacle surface; antheridia yellowish, small, sessile on branched multicellular paraphyses.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera,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.
