Note: Although Kornmann accredited the names of both the genus and the species to Kuckuck, the author should be Kornmann since Kuckuck did not recognize this genus in his manuscript. Some authors prefer to assign the genus to the Ectocarpaceae, but we follow Parke & Dixon (1976: 559) and Fletcher (1987: 116) in including it in the Myrionemataceae.
Myrionema speciosum Børgesen, 1902: 421–424, fig. 78 (type locality: Vaags Ejde, Syderø, Faeroes).
