Metapeyssonnelia Boudouresque, Coppejans & Marcot-Coq., 1976
Holotype species: Metapeyssonnelia feldmannii Boudouresque, Coppejans & Marcot
Original publication and holotype designation: Boudouresque, C.-F., Coppejans, E. & Marcot, J. (1976). Un nouveau genre de Peyssonneliaceae, Metapeyssonnelia (Rhodophyta). Phycologia 15: 283-288.
Description: Plants are orbicular, encrusting, anchored by unicellular rhizoids, and completely calcified. The interiors of young thalli are Peyssonnelia-like, but towards the margins the blades become differentiated into a superior and inferior perithallus. Cells of the hypothallial layer in such cases produce a single coxal cell only, in contrast to the paired arrangement of coxal cells in Polystrata. Reproductive structures are unknown.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera,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.
