The plurilocular sporangia are simple or branched, 58 — 100 fx long and 5,8 — 7 a broad; in the central portion of the disc they have a 20—40 u long stalk consisting of 1 — 4 cells, but nearer the margin they are often sessile. The sporangia consist usually of a single series of loculi and I have but seldom observed two series in the middle portion.

Some of my specimens were for the most part composed of unbranched, 100—140 a long and 6 — 7 tj. broad, assimilative filaments, the cells of which were twice as long as broad. I have only met with lateral hairs, which some- times were more than 400 fi long. As far as I can judge from my alcohol materia], there is only one chromatophore to be found in each cell. Weil. Fig. 2. Fig. 3. Myrioncma Corunnæ Sauv. Fig. 2. a two branched, sterile filaments, one with a lateral hair, the other with a lateral plurilocular sporangium; b 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 ; b 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, F (), 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 1 have said before, fully agreeing with Sau- vageau's description and figures (1. c), and they also agree very well with the Færoese specimens mentioned by Börgesen (Fær. 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 readability -
