1797 J. Stackhouse Nereis Britannica (1801) ii. p. xvi Codium. Fructification—invisible; frond roundish; soft and spungy, when wet; velvety, when dry.

1799 Analyt. Rev. Mar. 278 We cannot avoid remarking, that the shape of the frond cannot be admitted as a mark of generic distinction, as in the genus Codium.

1883 Cornishman 22 Mar. 6/2 Mr. Tellam has no doubt that this rare codium may be found on other parts of our coast, if carefully searched for.

1918 Bot. Gaz. 65 135 The species of Codium all have stout holdfasts, and require a knife or chisel to collect them.

1986 P. Matthiessen Men's Lives v. 55 We turned to heavy labor with the dredges, dumping the wet loads of eelgrass and codium,..onto the culling board.

2005 A. Ricciardi in H. A. Mooney et al. Invasive Alien Species vii. 167 The emergence of Codium as the dominant alga has disturbing implications for Atlantic coastal fisheries.
