Request PDFDescription: Rhodymeniacean taxa with a medulla of large cells, typically two ordered rows near apices in some species, in irregular arrays in others, the cells separated by intervening spaces with small intercalating cells. Tetrasporangial sori initiated by the swelling of pre-existing (i.e., not adventitious) intercalary and terminal outer cortical cells, some converting to sporangial production, others compressed between developing sporangia appearing as 1–2- celled sterile filaments, but the general impression is that most outer cortical cells will eventually convert to sporangial production. Tetrasporangial sori are confined to a single thallus surface in some species, produced predominantly on one surface in others, or developing equally on both surfaces, but with one side lagging in development relative to the other. Sori are initially circular to oval, but expand with age to become oblong to cordiform (where branch tips are dichotomous). Cystocarps are protuberant, spherical or occasionally hemispherical, weakly to strongly basally constricted, and ostiolate; pericarp chambers are lined to varying degrees with an anastomosing network of typically stellate cells. Spermatangial mother cells, where known, are typically columnar to obpyriform.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera,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