The following names are considered synonyms of G. tenuissima: Gelidium tenuissimum Thuret, G. pannosum Bornet non Grunow, G. pannostem Weber van Bosse, Echinocaulon pannosum Feldmann, Gelidiella pannosa (Bornet) Feldmann & Hamel, G pannosa (Feldmann) Feldmann & Hamel, and G. tenuissima (Thuret) Feldmann & Hamel.
