Notes: Recent revisions based on molecular and morphological phylogenies of Gomphonema and its allies ( Jahn & al. 2019) resulted in the recognition of a monophyletic grouping around Gomphonema olivaceum (Hornemann) Ehrenberg and allies. Gomphonema olivaceum was originally described as Ulva olivacea Hornemann (1810 : fasc. 24; pl. MCCCCXXIX [1429]), which was transferred as Gomphonella olivacea (Hornemann) Rabenhorst (1853: 61 , pl. IX [9]), the generitype of Gomphonella Rabenhorst, 1853 . As a result, Jahn & al. (2019) resurrected the genus Gomphonella to define this monophyletic grouping. One taxon that was not transferred on the basis of this resurrected name was Foged’s Gomphonema olivaceoides var. densistriatum , which has all the characters ( Foged 1963, Bishop 2017) of the resurrected genus Gomphonella ,

_

necessitating this transfer and a new name at the species level as Gomphonella densistriata (Levkov) R.Jahn & N.Abarca is already occupied.
