d. ditto, less magnified; in this case, the contents of the 
spore form a lobed gelatinous mass, which, with the inclosed 
branched colourless threads, resembles very much a Che- 
tophora. 
e. threads from a germinating spore, showing the inarticu- 
late slender threads of the centre, and the dichotomous moni- 
liform threads which arise from them. These gradually in- 
crease in size, acquire a brown colour, and at length assume 
the characters of the perfect plant. 
f. a portion, less regular, very highly magnified. 
f. a spore, giving out threads from the cells of the 
peridium. 
h. a portion of the same, more highly magnified. .

n. 1089. ; 
Clay banks near Maranham. June 1841. 
The specimens, compared with one from Schweinitz, pre- 
sent but little difference. They differ, indeed, more from — 
the technical characters, as given by Fries and Schweinitz, 
having the ultimate ramuli, for the most part, simply elon- 
gated, but amongst them are some which are dilated above, 
and almost plumose. In the greater number of individuals 
from a compressed stem, arise a large quantity of branches, 
disposed, in well grown specimens, in a palmate manner, with 
the ultimate ramuli half as high as the whole plant, and ex- 
tremely acute. Some crowded individuals show little of the 
palmate arrangement. Tufts about 1 inch high. >
