On decaying flicks, leaves, &c. in a ditch at Stoke Newington ; Jofeph 

 JVootls, junr. Efq. 



Mr. Woods difcovered this fpecies growing in flippery maffes about one 

 and a half inch long, of a purple brown color, and forming a thick coat 

 over decaying fubftances in a ditch. at Stoke Newington. The length and 

 diameter of the joints is equal, and in the middle of each there is the 

 appearance of a dark narrow tranfverfe band, which however proceeds 

 from the internal organization of the plant, and therefore appe.irs fomewhat 

 fhorter than the diameter of the filament. For the drawing in my fup- 

 plementary plate B, which was made with power I of the microfcope, I 

 am indebted to my friend Mr. Woods.

Among the leaves of water plants in the River Lea at Walthamftow. 



In March, 1802, I found a fingle fmall fpecimen of this fpecies amonc 

 a jelly-like fubftance of the Tremella kind, which almoft covers the water 

 plants in the Lea at Walthamftow. The filaments are fimple, very brittle, 

 contracted at the diflepiments, and of a brown color. The length of the 

 joints in fome filaments is about thrice, and in others not more than twice 

 the diameter, and they are generally marked with one or two tranfverfe 

 lines at uncertain diftances from each other. I have not fince b;en able to 

 find more than a few imperfect filaments of this plant, and in one of thefe 

 now before me, I obferve one or two joints much fhorter than the others, 

 whole length fcarcely exceeds the diameter, and which in appearance fome-
