Abstract

Boudouresque, C.F.; Coppejans, E.; Marcot, J. (1976). Un nouveau genre de Peyssoneliaceae, Metapeyssonnelia (Rhodophyta). [A new genus of Peyssoneliaceae, Metapeyssonnelia (Rhodophyta).]. Phycologia 15(3/4): 283-288

Metapeyssonelia, a new genus of the Peyssoneliaceae (Rhodophyta), is described. This encrusting orbicular alga is completely calcified by aragonite. Small unicellular rhizoids are present. The centre of the thallus shows a Peyssonnelia-like structure that metamorphes towards the margins of older thalli: in these metamorphosed parts, an inferior perithallus is generated downwards. Each hypothallic cell gives rise to only one coxal cell, even in the metamorphosed parts: this characteristic distinguishes the structure of Metapeyssonelia from that of Polystrata. The type species is M. feldmannii nov. sp., collected at Port-Cros island (Mediterranean, France).
