Of these (Edogonium, Link, isidentical with Mr. Hassalls Vesiculifera, and with the still olderTiresias, Bory, which latter name should be adopted. Confervais retained for the species with simple threads, whose fruit is im-perfectly known. Rhizogonium is proposed for Conf. riparia, Ag.,and its allies; while sEgagropila, founded on C. cegagropila andSpongomorpha, on C. uncialis, I include in the genus now calledCladophora. It would be clearly a most artificial arrangementto separate C. uncialis generically from C. lanosa and C. arcta. Fig. 1. Cladophora lanosa :—natural size. 2. Portion of a filament 3.
