Chlorhormidium flaccidum (KÜTZ.) FOTT: 1 = filaments from the film layer in Bold liquid medium, 2 = filaments from the cotton-wool-like filament mass in Bold liquid medium other and follow a finger-print-like pattern. In the alga coat, the filaments are not arranged thus, but form a mere tangle, built up of longer or shorter filaments. The filaments comprising the film layer in definite pattern are much longer at places, the cells are more elongate than those in the alga coat (Fig. 1). In the cells of both formations, there are characteristic apical vacuoles which do not stain
