Description: Thallus with thin membranous blades when young, developing a reticulum distally that can extend to the margins or terminate submarginally. Growth by means of a marginal row of obliquely dividing apical cells; new blades occasionally proliferating from the terminal margin, resulting in membranous regions alternating with mesh-like regions. Membranous portion with 1–5 cell layers; veins lacking; margins smooth or denticulate. Spermatangia in small sori on the network or the membranous blades. Cystocarps borne on the network or marginal membranous portion, with a distinct ostiole; carposporangia solitary or in chains of 2 or 3, terminating gonimoblast filaments. Tetrasporangia in small sori on membranous and network partitions, tetrahedrally divided.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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