Lyngbya glutinosa C. Agardh, 1824: 73 (type locality: "In sinu Codano'' [Kattegat, between Denmark and Sweden]).
Hydrocoleum glutinosum (C. Agardh) Gomont, 1890: 353.—Jadin, 1894: CLXV.— Forti, 1907: 318–319 (`Hydrocoleus glutinosus').— Hodgkin, 1959: 9.

Note: Drouet (1968: 263), incorrectly treating Lyngbya glutinosa as a nomenclatural synonym of Conferva majuscula Dillwyn (1809 [1802–1809]: 40, suppl. pl. A), referred this species to Microcoleus lyngbyaceus (Kützing) P. Crouan & H. Crouan on the basis of the Dillwyn type. In fact, C. Agardh (1824: 73, 74) cited "Osc. majuscula, Lyngb. & fl. D. t. 1549. f. 1'' under Lyngbya glutinosa, intending this citation to refer to a circumscription (Lyngbye, 1819: 91) that excluded the type of Conferva majuscula, which he cited in the synonymy of Lyngbya crispa (C. Agardh) C. Agardh, as "Oscill. majuscula, Dillw. t. A.''.
