1. Representatives of the generaUlothrix, Monostroma, Gomontia, Hormiscia, Acrosiphonia andSpongomorpha, though widely differing in morphological characters of their gametophytes, agree in the presence and similar development of a unicellular sporophytic Codiolum-stage.

2. These genera have been united into a new class, Codiolophyceae, to indicate a high degree of phylogenetic relationship, thus eliminating at the same time the present unsatisfactory classification into 3–4 different orders of the Chlorophyta.
