| <i>Metapeyssonnelia</i>, a new genus of the Peyssonneliaceae (Rhodophyta), is described. This encrusting orbicular alga is completely calcified by aragonite. Small unicellular rhizoids are present. The centre of the thallus shows a <i>Peyssonnelia</i>-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 <i>Metapeyssonnelia</i> from that of <i>Polystrata</i>. The type species is <i>M. feldmannii</i> nov. sp., collected at Port-Cros island (Mediterranean, France). |
