Description: Thallus shortly stipitate or sessile with lobed or rounded blades with age becoming divided and laciniate. Structure multiaxial, composed of a mostly filamentous medulla; cortex composed of three to five layers of isodiametric cells in size decreasing towards the surface; stellate cells forming a compact subcortical layer. Dioecious; polycarpogonial three-celled carpogonial branches borne on supporting cell, which also produces four to six subsidiary cells. Fusion cells and connecting filaments are present, auxiliary cells not identified. Gonimoblasts arising from vegetative cells. Carposporangia formed in groups, intermixed with filaments. Carposporophytes immersed in young thalli, in mature thalli progressively more protuberant. Spermatangia in superficial sori on both sides of the lamina. Tetrasporangia not found in thalli bearing blades. Carpospores germinate to produce crustose thalli.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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