Noun

 * 1858, Peter Redfern, quoted in Quarterly Journal of Microscopical Science; Volume VI, page #96:
 * The extent of the cœnœcium rarely exceeds an inch on the Kincardineshire specimens, but it extends for three or four inches on those gathered in Dublin Bay and North Wales.
 * […]
 * The cœnœcium is thick in the centre ; thin, and composed of the last-formed individuals at the edges. The cells radiate from the centre, and they are imbricated in various degrees in different parts, the whole length of the cell, or merely its summit, being visible on the surface. The arrangement of the cells is variable, but generally alternating. When allowed to dry on the plant, the cœnœcium presents the appearance of a wrinkled, hairy membrane ; when it is sliced from the plant, and dissected with needles, a large quantity of viscid matter escapes from its cells.
 * 1872, Henry Alleyne Nicholson, A Manual of Palæontology, William Blackwood and Sons; Volume I, Chapter XVIII, page #196:
 * The entire cœnœcium is calcareous. In the nearly allied genus Retepora, the cœnœcium is also a fan‐shaped expansion, and is also of a calcareous consistence. In place, however, of transverse dissepiments, the branches of the cœnœcium unite with one another in such a manner as to form ovate interspaces or “ fenestrules.” The outer surface of the cœnœcium is non‐celluliferous and minutely striated.
 * 1887, Richard H. Moore, in The Journal of Microscopy and Natural Science, Bailliere, Tindall, &; Volume VI, page #71:
 * The under surface of the cœnœcium is stated to be well adapted for the purpose of locomotion, resembling in its central portion the foot of a gasteropodous mollusc. From the longitudinal disc or foot, which is contractile, a large flattened margin extends beyond the external series of orifices ; and a regular arrangement of tubes can be seen within the outer membrane, but having no external openings. Towards the end of the season the central upper portion of the cœnoecium is studded with dark circular bodies ; these are the “  statoblasts,” which are destined to form the colonies of the succeeding season, and which have been observed only in Cristatella and one other species.
