Description: Member of the Kallymeniaceae with foliose blades; medulla lax, with an interconnected network of slender filaments and stellate cells; inner cortex typically one or two layers of periclinally elongated cells internal to two or three layers of smaller cortical cells that decrease in size towards the surface. Nonprocarpic; supporting cells either mono- or polycarpogonial, also carrying up to ten subsidiary cells; supporting cell, carpogonial branch cells and subsidiary cells typically elongate to some degree. Fusion cells, where known, prominent, deeply lobed, incorporating the supporting and subsidiary cells and issuing long connecting filaments. Auxiliary cell systems formed by the auxiliary cell bearing up to six subsidiary cells. Gonimoblast filaments develop from the auxiliary cell or from the connecting filament near the site of fusion with the auxiliary cell.

Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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