Current status. Species inquirenda.

Remarks. Fraser (1941b) designated material at the NMNHAbout NMNH ( USNMAbout USNM 43454) as the “ type ” of Campanularia fasciculata  . Although the specimen count of the species in the NMNHAbout NMNH online database is listed as “1”, the collection is currently listed as syntype material. We believe the type represents several pieces of a single colony, growing on a barnacle, and therefore constitutes a holotype. Colony fragments in the Fraser Hydroid Collection at the RBCMAbout RBCM ( BCPMAbout BCPM 976-00346-001), labelled “cotype”, are paratypes. Other material assigned to the species in collections at the NMNHAbout NMNH ( USNMAbout USNM 86217, USNMAbout USNM 86218) were collected during the 1980s and are not types.

This species was assigned by Fraser (1941b), with question, to Campanularia Lamarck, 1816  . It is unlikely referable to that genus in having hydrothecae with a true diaphragm rather than a basal annular thickening of perisarc, in lacking a characteristic subhydrothecal spherule, and in having an erect rather than a typically stolonal colony form. In such characters, the hydroid conforms with species of Obeliidae Haeckel, 1879 rather than Campanulariidae Johnston, 1837  . Cairns et al. (2002: 58) included C. fasciculata  as a possible synonym of Obelia longissima ( Pallas, 1766)  . That now seems unlikely based on its colony form. While the hydroid somewhat resembles O. longissima  , it differs in the mode of branching and in having a peculiar polysiphonic hydrocaulus. The species is currently regarded as a taxon inquirenda in WoRMS, a view adopted here. Gonophores were not observed in the type material, adding to uncertainties about classification of the species. The binomen Campanularia fasciculata  is provisionally retained for it here given its doubtful affinities.
