Description: Plants epiphytic, attached with a small discoid holdfast, ligulate, polystichous, composed of 2 fairly distinct tissues, medullary layer and cortical layer. Medullary layer consisting of large colorless, closely united cells. Cortical layer consisting of small, cubic, pigmented cells. Phaeophycean hairs present occasionally forming tufts. Unilocular sporangia projected from the surface, surrounding hair tufts. Plurilocular sporangia not detected on erect thalli. Very close to Punctaria, distinguished by the presence of projected unilocular sporangia and distinction between medulla and cortex.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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