CRYPTOGAMIA. FUNGI. Agaricus. 
Stem hollow, white, viscid, tender, easily broken, splitting-, three or four 
inches high, thick as a crow quill. 
Ag. stipitatus , pileo hemisphoerico sordido: umhilico prominente , lamellis albis , 
stipite longo cylindraceo albo. FI. Suec. 1216. 
Pilous hemispherical, generally with a pointed boss, viscid. Gills white, 
not hollow underneath, their sides sprinkled with a dark coloured powder. 
Stem cylindrical, long, slender, white. Linn. 
Some doubt exists whether we are right in considering this species as the 
same with the clypeatus of Linnaeus. He says the gills are white , but the 
circumstance of "their being dusted with a dark-coloured powder may give 
them the colour we have described. He refers to Haller Enum. 41. 35, 
where that author describes them as very white ; in every other respect 
his description applies exactly to our plant, and he refers at 2388 of his 
Hist. Helv. to the same figures which we have found to correspond with 
ours. This in many respects resembles Ag. varius, but the elastic firm and 
wiry stem of that is very different from the tender texture of this. Mr. 
Stackhouse.

Var. 2. Gills darker brown: pileus powdery. 
Pileus white and powdery, but the powder easily falling off shows a red¬ 
dish brown ground. 
This is larger than the preceding, the diameter of the pileus being sometimes 
more than two inches, the stem six inches long, and as thick as a goose 
quill. 
Packington park, Warwickshire. Autumn. 
Ag. fimi-pu'tris. (Bull.) Gills dark brown to black, four or eight 
in a set: pileus pale brown, conical, blunt, apex polished: stem 
white. 
Bull. 66. very exact , but the stem more coloured than ours. 
Gills fixed, dark brown, changing to black and liquefying; numerous, 
mostly four, but in the full expansion of the larger plants, eight in a set. 
Pileus pale dead brown, conical, blunt, apex more or less smooth and 
polished, sides a little streaked, thin, semi-transparent, one to two inches 
from the edge to the top of the cone, and as much in diameter at the base, 
forming an equilateral triangle. Top of the pileus sometimes slightly 
tinged of a chesnut colour. 
Stem hollow, silvery white, splitting, cylindrical, two to five inches high, 
thick as raven’s quill.

In all other respects similar to the above, but not more than half the size.

colour, conical, pointed : stem mouse-colour, cylindrical, firm.

species, proving nearly fatal to a stout man. E.)
