Xenia umbellata Lamarck, 1816

Emended diagnosis.

(Chiefly after Halász et al. 2019). Colonies are small and soft with cylindrical stalk, undivided or branched, terminating in one or more domed polyp-bearing regions. Polyps are not retractile and are always monomorphic. The dominant sclerites are ellipsoid platelets, usually abundant in all parts of the colony. They are composed of calcite rods, often dendritic or sinuous, mostly radially arranged, at least at the periphery of the sclerites. In addition to ellipsoid platelets, a few species have rods or unique spindles with pointed spear ends.
