CRYPTOGAMIA. 501 



or less accurately defined. Splendid and 

 accurate works, illustrative of this Order, 

 have been given to the world by Schaiffer, 

 Bulliard and Sowerbv, which are the more 

 useful as the generality of fungi cannot 

 Mell 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 Mtthodica Fnngorum helps 

 us to the following arrangement. 



1. Augiocarpi, such as bear seeds in- 

 ternally. These are either hard, like 

 Spharia, Sonerb, Fung, t. 159, l60 ; or 

 membranous, tough and leathery, like 

 Lijcoperdon, t. 331, 332; Ci/athus (M- 

 dularia) t. 28, 29; or Batarrca {Lyco- 

 pcrdon) t. 390. 



2. Gynmocarpi, such as bear seeds im- 

 bedded in an appropriate, dilated, exposed 

 membrane, denominated hymenium, like 

 llelvella, t. 39, in which that part is 

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

 in which it is porous ; and the vast genus 

 Agaricus, t. 1,2, cS:c., in which it consists 

 of parallel plates called lamelUc, or gills.
