Fig. 382. SPH^ROZYGA BROOMEI. 



Colour. Deep green. 

 Suhstance. Gelatinous; slimy. 



Character of Frond. Filmy patches, consisting of minute straight threads {filaments)) 

 unbranched; lyiug together in a 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 \, filaments ^jl^j of an inch long. 



Fructification. Minute seeds {zoos^jores) formed in the enlarged colour-cells, which 

 are then oval, twice as long as wide, not much wider than the ordinary cells, 

 and brown. 



Uahitat. In a brackish ditch at Shirehampton. On dead leaves. 



Fig. 383. SPHJiROZYGA BEEKELEYANA. 



Colour. Vivid green. 



Substance. Very gelatinous; slimy. 



Character of Frond. Filmy patches, consisting of minute curved threads {filaments) ; 

 unbranched; 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 -j^^ 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) inter- 

 mixed here and there. At maturity, some of the colour-cells run together, 

 forming larger ones (a microscopic object). 



Measurement. Fleecy layers ^ 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 chesnut brown. 



Habitat Muddy, brackish ditches at Shirehampton, Found with Sphcerozyga Broomei.
