Description: Plants forming small pulvinate tufts, without penetrating the tissue of the host, attached by rhizoidal filaments. Medulla hyaline, well-developed, pseudoparenchymatous, forming a basal hemispherical cushion with radiating branched filaments. Cortex consisting of assimilatory filaments and plurilocular reproductive structures. Paraphyses present or absent. Assimilatory filaments free, uniseriate, simple or with short branches at the base, below the meristimatic zone. Meristimatic zone conspicuous. Cells of the assimilatory filaments with numerous discoid chloroplasts, each with a pyrenoid. Two types of plurilocular structures: multiseriate, terminal, from the uppermost cells of the medulla, and intercalary by transfomation of vegetative cells of assimilatoty filaments.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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