I have only met with lateral hairs, which some- times were more than 400 tx long. As far as I can judge from my alcohol material, there is only one chromatophore to be found in each cell. Well. Fig. 2. Fiij. 3. Myrionenia Coranncp. Sauv. Fig. 2. a two branched, sterile filaments, one with a lateral hair, the other witli a lateral plurilocular sporangium: h to the left an assimilative filament and a rhizoid consisting of two cells, to the right a stalked plurilocular sporangium. (126:1.) Fig. 3. a shows stalked and divided plurilocular sporangium and a short rhizoid; h shows an assimilative filament and two rhizoids, the one of which (to the left) not yet separated from the mother cell with a wall, the other (to the right) consisting of one cell. (316 : 1.) developed rhizoids, like those figured by Sauvageau in fig. 14, /' (), are frequent in my material; they penetrate the sorus and grow inwards between the paraphyses and sporangia of the host-plant. My specimens are, as I have said before, hilly agreeing with Sau- vageau's descrii)lion and figures (1. c), and they also agree very well willi the Faeroese specimens mentioned by Borgesen (Fser. alg. p. 426), which were sent to Please note that these images are extracted from scanned page images that may have been digitally enhanced for readabi
