or less accurately denned. Spiendra and 

 accurate works, illustrative of this Order, 

 have been given to the world by Scnaeirer, 

 Bulliard and Sowerby, which are" the more 

 useful as the generality of fungi cannot 

 well be preserved. The most distinguished 

 writer upon them, indeed the only good 

 systematic one, is Persoon, who has more- 

 over supplied us with some exquisite figures. 

 His Synopsis Methodica Fimgorum helps 

 / m to the following arrangement. 



1. Angiocarpi, such as bear seeds in- 

 ternally. These are either hard, like 

 Spharia, Sowerb. Fung. t. 159, 160; or 

 membranous, tough and leathery, like 

 Lycopcrdon, i 331, 332; Cyathm (A 7 /- 

 dularia) t. 28, 29; or Batarrea (Lyco- 

 perdon) t. 390, 



2. Gymnocctrpi, such as bear seeds im- 

 bedded in an appropriate, dilated, exposed 

 membrane, denominated hymenium, like 

 Helvetia, t. 39, in which that part is 

 .smooth and even; Boletus, t. 34, 87, 134, 

 in which it is porous; and the vast genus 

 AgartcuL u lJ 2, &c., in which it consists 

 of parallel plates called lamella^ or gill*,
