more dainty kinds. Agaricus pratemis of Sowerby is not the one mider consideration but A. oreades, the 

 Champignon. The shape of the vaulted gills is a striking peculiarity m the few Agarics which are placed 

 in the division Camarophylli ; the gUls are also very tliick and distant, and connected by prominent tumid 

 veins. In wet weather the pileus cracks from excessive expansion, and contracting again forms a number of 

 concentric \mnkles in the smooth leathery epidermis, but it is not zoned. The true shape and character of 

 A.pratensis is that given in the drawing; soil and season cause it frequently to vary much from this 

 portrait, but a little attention wiU enable the original to be identified. It has white spores ; it is not 

 furnished with milky juice, it has no kiud of veil, consequently no sheath or ring at any period of growth ; 

 and the name CHtocybe, from the shape of the pileus rising in the viiddle, points out a distinction from the 

 class Omphalia, in wliich the pileus is dimpled in the centre when youjig. 



With a Virgineus it will not be confounded, if the colour and consistency are carefully examined ; nor 

 witli C. Cibarius, if the test of the gills bemg separable from the pileus or not, be applied ; there is no 

 dangerous species allied to it.
