AMANITA. 261 



with a membrane which in course of expansion either falls 

 oif or forms a deflexed ring. 



Stem 3-4 in. high, half an inch thick, fibrillose with a 

 few adpressed scales arising from the partial ring which was 

 at first in contact with it, attenuated upwards, bulbous 

 below and there furnished with a variously lobed volva, 

 which is adnate with the base of the stipes, but has the 

 margin free and more or less expanded, in general hollow at 

 the apex or for some distance down, though occasionally the 

 inner substance is only a little more spongy than the outer, 

 varying much in size and colour and degree of scaliness, and 

 according to Fries in the manner of adherence of the volva. 

 When fresh it has a powerful but not disagreeable smell ; 

 when past maturity, its odour becomes almost insupportable.
