ResumoThe occurrence of the Conchocelis-phase of a species of Porphyra in the peduncular scales of the barnacle, Pollicipes cornucopia at Roscoff, France, is recorded. This Conchocelis-growtb. closely resembles that described by Batters as G. rosea, the only species in the genus created by him. It is also identical with growths of Gonchocelis originating from spores of Porphyra umbilicalis (L.) Kiitz. in culture. A study of the fertile cell rows occurring in the peduncular scales of P. cornucopia suggests that, by the breakdown of the transverse walls, tubes are formed and that the spores pass along these to the surface of the scales and are there liberated into the sea. The ecological importance of the Gonchocelis-phase in the life history of Porphyra is stressed.
