Cells usually united into a small cluster by a gelatinous substance. Franceia Lemmermann. Chromatophores two, each with a pyrenoid. This genus in its general characteristics resembles Richteriella but it is distinguished from it by the larger size and oval shape of the cells, the shorter spines and the two chromatophores. Reproduction takes place by division in a single longitudinal direction. Fig. 185. Franceia sp. X about 600. (Original.).
