GELIDIELLACEAE

Note: The genus Gelidiella was segregated into its own family, Gelidiellaceae, by Fan (1961: 317) on the basis of two characters: the lack of medullary hyphae (rhizines); and the lack of a sexual phase in its life history. Subsequently, Sreenivasa Rao & Trivedi (1980b) found cystocarps in an undescribed species of Gelidiella from India (later described as G. diuens) while Maggs & Guiry (1988) found medullary rhizines at the attachment points of G. calcicola, a repent species newly described from the British Isles and Atlantic France. Subsequently, Guiry & Womersley (1992) recorded cystocarps and spermatangia in G. minima from southern Australia. Maggs & Guiry concluded that retention of the Gelidiellaceae separate from the Gelidiaceae was not warranted and, moreover, expressed doubts as to the validity of the criteria used to delimit Gelidiella from Gelidium. Hommersand & Fredericq (1988), when reviewing the Gelidiales, noted the opinion of Maggs & Guiry, but abstained from endorsing it. R. Norris (1992a), emphasizing the lack of rhizines in Gelidiella, redefined the family and transferred G. calcicola to Gelidium.

Note: Fucus rigidus Vahl, the intended basionym of Sphaerococcus rigidus, is not priorable since it is a later homonym of F. rigidus Turra (1780: 68; type locality: Italy), a name of unknown application. Sphaerococcus rigidus C. Agardh is treated as a nomen novum in accordance with Art. 58.3. Fucus spiniformis is included as a synonym on the authority of C. Agardh (1822 [1822–1823]: 285–286), Sphaerococcus rigidus on the authority of Børgesen (1932c: 5), Echinocaulon spinellum on the authority of J. Feldmann (1931a: 162), and Gelidium corneum var. setaceum on the authority of Papenfuss (1968c: 73). The misapplication of Gelidium micropterum was noted by Sreenivasa Rao (1971c: 65–67), that of Gelidiopsis rigida var. semipinnata by Hatta & Prud'homme van Reine (1991: 351, 353). The name Gelidiella acerosa forma minima was originally cited without a description (Sreenivasa Rao, 1969a: 46). Hatta & Prud'homme van Reine (1991: 351, 353) do not accept this forma, noting that the dimensions given by Sreenivasa Rao fall within the range displayed by Indonesian material of Gelidiella acerosa.
