with some tendency to unilaterality. The cells are cylindrical, not constricted at 
the transverse walls, (7,5—)9—11 (—12)y broad, 3—7, usually 4—5 diameters long. 
They contain a parietal chromatophore with a large parietal pyrenoid much pro- 
jecting into the interior of the cell. In the older cells the chromatophore is larger 
than in the younger and perhaps somewhat lobed. Hyaline hairs do not occur. 
The germination was unfortunately not observed. 
The sporangia are borne on branch- 
lets, usually placed on the inner side of | MER 
the branches near their base, very often S NN 
two or three seriate. The branchlets N. RA 
are as a rule one- or two-celled; in the SK 
first case it bears a terminal and a la- 
teral sporangium, in the latler the upper 
cell behaves in the same way, while the N EN 
lower cell bears one or two sporangia. Ÿ, | 
It happens however that the branchlets _ WW f 
may consist of more than two cells and = 
that they may be branched (fig. 54 D). SS 
Only rarely the sporangia may be ses- 
sile directly on the filaments. The spor- 
angia are always monosporous, oblong, ik 1 
18—19 » long, 9—10,5 » broad. Renewal 
ofthe emptied sporangia from the under- 
lying cell frequently occurs. \ 
As already said, the Danish spec- Se \ 7

of DE Noraris from Genoa. ARDISSONE IN LS Vp

rently sessile sporangia (1867 fig. 3); the \ IF

it by the absence of sex-organs and by 
the want of a larger cell originating from the germinating spore and giving off 
erect filaments and descending endophytic filaments. In spite of repeated search I 
have never found such a cell and that is in accordance with Bornet’s statement
