Cryptogamie is divided into three sections, each published as an individual publication: Cryptogamie, Bryologie, Cryptogamie, Algologie and Cryptogamie, Mycologie. Cryptogamie is a French journal of international scope publishing in several European languages. It accepts original papers and review articles on the systematics, biology and ecology of all cryptogams (algae; bryophytes; fungi and lichens, respectively).

Founded in 1924 by Pierre Allorge (1891-1944) and Gontran Hamel (1883-1944), Cryptogamie, Algologie was published as Revue algologique between 1924-1941 and 1954-1979.
