Notes 
From editor or global species database
Checked: verified by a taxonomic editorDiagnosis Hydroids sessile, hydranths often polymorphic, usually epizootic; hydrorhiza either perisarc-covered stolonal tubes, or as an encrusting mat resulting from the coalescence of the stolonal system, either covered by a common layer of perisarc or with naked coenosarc; in some genera the hydrorhizal mat is reinforced by a calcareous skeleton; frequently with chitinous or calcareous spines forming sometimes pillars and branches, sometimes with protective tubes overarching the hydranths; gastrozooids either with one or several whorls of filiform tentacles beneath hypostome, or with scattered tentacles on the upper half of the body, exceptionally with one or two tentacles only; dactylozooids, when present, with no tentacles. Gonophores typically borne on gonozooids, these with one or more whorls of filiform tentacles or without tentacles and mouth (= blastostyles), giving rise to fixed sporosacs, eumedusoids, or free medusae.
Medusa umbrella more or less bell-shaped, with or without slight apical process; manubrium tubular to sac-shaped, not extending beyond bell margin; with or without gastric peduncle; mouth with four simple or branched oral lips drawn out to form arms with terminal nematocyst clusters; four, eight, or more, solid, marginal tentacles, tentacles not in groups; four radial canals and circular canal; gonads on manubrium, interradial, sometimes extending along basal, perradial protrusions of the manubrium; with or without ocelli. [details]

Checked: verified by a taxonomic editorTaxonomy Several genera of the Hydractiniidae have been redefined by Miglietta et al (2010, 2012) based on molecular phylogenies. Many of these genera are now not diagnosable by morphological traits. Moreover, not all species were included in the phylogeny and thus for some Hydractinia species it is unclear to which genus they belong. If it is unlcear to what genus a hydractiniid species belongs, then Hydractinia should be selected as default. More revisory work is clearly needed to obtain a stable system [details]
