DOWNY AGARIC. 



TAB. CLVI. 



'TpHE root is fmall, black, and emits a few fhort brown fibres. 



The ftem is upright, cylindrical, hollow; the fubftance white, 

 and eafily torn in filaments; it is covered, on the outride, with a 

 lead-coloured down. 



The gills are arranged in three feries ; thofe of the firft feries 

 long and narrow; they are white on the fides, but furnilhed with 

 a black down or powder on the edges, which, before the plant is 

 torn, makes them appear wholly black. 



The pileus is at firft oval or oblong ; when the rim begins to 

 enlarge it becomes of a pyramidal figure; at laft bell-fhaped, 

 lacerates, and foon diffolves. In its firft fiages it is thickly covered 

 with a gray or lead-coloured down, which covering tears in frag- 

 ments as the pileus extends in breadth, and remains on its white 

 ftriated furface, in broken, deformed, gray patches. 



I gathered this fpecies near Ogden~Kirk y amongft wet mofs, 

 in the ground where peat is dug for fuel.
