The vegetable nature of this order of plants was long 
doubted by some naturalists, who were disposed to as- 
cribe to them an animal origin ; but the labours of Dry- 
ander, Schaeffer, and Hedwig, have shewn that they 
possess a vegetable character, by detecting their seeds, 
and explaining the parts of fructification. In the Sy* 
yiopsis Methodica Fungorum of Persoon, the order of 
mushrooms is divided into such as produce their seeds 
internally, or in vessels, and such as have them expos- 
ed or imbedded in an appropriate membrane. To the 
first division belong Sphceria and Lycoperdon, or Puff- 
ball y and to the second Helvetia, in which the seed- 
membrane is smooth and even •, Boletus , in which it is 
porous ; and Agaricus, in which it is composed of pa- 
rallel plates, denominated Latnellce, or Gills.
