Fig. 382. SPH^ROZYGA BROOMEI. 
Colour. Deep green. 
Substance. Gelatinous ; slimy. 
Character of Frond. Filmy patches, consisting of minute straight threads {filaments) ; un- 
hranched ; lying together in n layer of jelly. 
Filaments. Formed of bead-like colour-cells, with here and there a larger, squarish, colourless 
one (called the connecting cell) intermixed. At maturity, some of the colour-cells 
run together, forming larger ones (a microscopic object). 
Measurement. Patches J, filaments of an inch long. 
Fructification. Minute seeds {zoospores) formed in the enlarged colour-cells, which are then 
oval, twice as long as wide, not much wider than the ordinary cells, and brown. 
Habitat. In a brackish ditch at Shirehampton. On dead leaves. 
Fig. 383. SPH^ROZYGA BERKELEYANA. 
Colour, Vivid green. 
Substance. Very gelatinous ; slimy. 
Character of Frond. Filmy patches, consisting of minute curved threads {filaments) un- 
branched ; lying together in a layer of jelly ; the younger ones often enclosed, several 
together, in a distinct gelatinous sheath. (See Figure.) 
Filaments. Formed of bead-like colour-cells, with here and there a larger, slightly-compressed, 
colourless one intermixed. At maturity, some of the colour-cells run together, forming 
larger ones (a microscopic object). 
Measurement. Patches J, filaments perhaps of an inch long. 
Fructification. Minute seeds {zoospores) formed of the enlarged colour-cells, which are then 
oblong, twice the width of the ordinary cells, and brown ; and lie, generally in pairs, 
on each side a connecting cell. 
Habitat. In a brackish ditch at Shirehampton. Amongst the filaments of Conferva fracta, 
&c. 
Fig. 384. SPERMOSIRA HARVEYANA. 
Colour. Brilliant green. 
Substance. Membranaceous ; scarcely gelatinous. 
Character of Frond. A fleecy layer of slender, much curled and twisted threads {filaments) ; 
unbranched ; tubular ; containing green colour-cells nearly as long as broad ; a longer, 
squarish, pale reddish one (called a connecting cell) intermixed here and there. At 
maturity, some of the colour-cells run together, forming larger ones (a microscopic 
object). 
Measurement. Fleecy layers J inch long ; filaments rather finer than human hair. 
Fructification. Minute seeds {zoospores) formed in the enlarged colour-cells, which are then 
exactly globose, almost twice the width of the common cells, and a fine chestnut 
brown. 
Habitat. Muddy, brackish ditches at Shirehampton. Found with Sphcerozyga Broomei.
