Description: Plants are minute (2-5 mm) parasites of Sarcodiotheca gaudichaudii, on which they form knobby, pustular outgrowths. The medulla is a mixture of subisodiametric cells mixed with rhizoids and is surrounded by a cortex of subisodiametric cells of peripherally decreasing size. Carpogonial branches are 2-3-celled, and auxiliary cells are well-differentiated before fertilization. Fertilized carpogonia emit 1 or 2 connecting filaments. Gonimoblasts radiate from a central sterile-celled placenta and fuse to unpigmented gametophytic cells and also pigmented host cells. Carposporangia are borne in chains and are surrounded by a non-ostiolate pericarp lacking a surrounding consolidated hull. Tetrasporangia are less common than bisporangia, the latter of which produce either uninucleate or binucleate spores. Uninucleate bispores are an asexual life history phase and result in production of plants producing binucleate bispores. Both tetraspores and binucleate bispores germinate to produce gametophytic plants (Goff 1981). Details of reproduction are presented by Goff and Hommersand (1982).

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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