AND VOLVA. 253 



his immortal Philosophia Botanica into 

 12 chapters and 365 sections, and reckoned 

 seven parts of fructification as well as seven 

 species of calyx. 



7- Volva. Wrapper, or covering of the Fun- 

 gus tribe, of a membranous texture, con- 

 cealing their parts of fructification, and in 

 due time bursting all round, forming a 

 'ring upon the stalk, as in A gar km pro- 

 cerus, Sozcerb. Fung. t. 190, and A. cam- 

 pestris, the Common Mushroom, t. 305.; 

 Such at least is the original meaning of 

 this term, as explained in the Phil. Bot.\ 

 but it has become more generally used, 

 even by Linnaeus himself, for the more 

 fleshy external covering of some other 

 Fungi, which is scarcely raised out of the 

 ground, and enfolds the whole plant when 

 young. SeeAgaricus volvaceus, t. 1, and 

 Ly coper don fornicatum, £.198; also the 

 very curious L. phalloides, t. 390, now 

 made a distinct genus by the learned Per- 

 soon, under the name of Batarrea pltal- 

 loidrs.
