THESE are globubar grains, of a fhining black colour, growing 

 clofe together in vaft numbers, and fo aptly reiembling fine gun- 

 powder, that, when I firft law the plant, I was for a moment aftu 

 deceived with it. I firft found it on the root of a large afh tree, the 

 trunk of which had been fawn off clofe by the ground; it covered 

 almoft the whole furface, in one fingle ftratum ; the plants being fepa- 

 rate, or not adhering to one another. 



Grows moft frequently on the end of the grain, on flumps of trees ; 

 rarely on the- fide of the grain. The old plants are perforated in the 



' 



centre, and white within.

THIS is of an intenfe black colour, the furface fhining, the figure 

 generally oblong or oval, fometimes irregular. It is of an hard 

 fubftance, and the rotundance of the black fphierula;, which are lodged 

 under the bark or common cover, make the furface feem as if covered 

 with low fmooth warts. The fubftance of the common cover is firm 

 and hard, and internally of a fair white; and is replete with fphasrulas, 

 which are of a glofiy black. 



It differs from the Spharia tuberculofa, in being of a black colour, 

 in being a larger plant, in its compreffed figure, in that the bark is 

 internally white, in that the iphferulas are more numerous, and in that 

 it grows on the external, not internal, rind or bark of fallen and decay- 

 ing branches of trees.
