Description: Uniaxial, terete or distinctly flattened, unbranched or distichously, subdichotomously or proliferously branched to about four orders. Midrib and lateral veins sometimes evident. Margins of ultimate order of branches sometimes fimbriate. Rhizoids surrounding axial cell and four medially situated periaxial cells. Cortical cells subspherical to elliptical, progressively smaller toward cuticle. Secondary pit connections lacking. Pit plugs lacking cap layers.
Monoecious or dioecious. Carpogonium terminating a long, usually unbranched, distally recurved, adventitious filament with slightly enlarged distal cells. Connecting filaments issuing from fusion process, contacting a succession of differentiated auxiliary cells occurring near distal ends of separate, unbranched, percurrent, adventitious filaments. No gonimoblast fusion cell. Most cells of cystocarp maturing into relatively small carposporangia. Carpostome lacking. Spermatangia superficial, cut off by oblique walls. Tetrasporophyte heteromorphic, crustose, Haematocelis- or Cruoriopsis-like. Tetrasporangia small, irregularly cruciate to irregularly zonate, attached basally.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera,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