AMANITOPSIS. 257 



white or pallid ; stem 4—5 iu. high, I in. thick at the base^ 

 equally attenuated upwards, very soft and at length fragile, 

 the entire surface broken up into squamules, hollow or with 

 line fibrils more or less occupying the cavity ; volva entirely 

 free from the stem, except a point at the extreme base, 

 sheathing, lax, fragile ; spores elliptical, 10 x 7-8 /x. 



Amanitopsis vaginata^ Roze, in Karsten, Hattsv., i. p. 7. 



Agaricus (^Amanita) vaginatus, Cke., Hdbk., p. 10 ; Cke., 

 Illustr., pi. 12, & 18.

Agaricus nivalis^ Grev., Scot. Cr. FL, t. 18 (the white 

 form). 



Among grass, in woods, &c. 



Pileus 4 in. or more broad, plane, slightly depressed in the 

 centre, scarcely umbonate, fleshy except at the extreme 

 margin, which in consequence is elegantly grooved; viscid 

 when moist, beaiitifully shining when dry; at first there 

 are a few broad scales, the remains of the volva, but these 

 soon vanish; the epidermis easily peels ofi". Gills free, 

 ventricose, broadest in front, often imbricated, white. Spores 

 white, round. Stem 6 in. or more high, J-1 in. thick, 

 attenuated upwards, obtuse at the base, where it is furnished 

 with a volva which is adnate for about an inch and then, in 

 general, closely surrounding it like a sheath, but sometimes 

 the margin is expanded, marked within at the base, with 

 the groves of the pileus, brittle, sericeo-squamulose, scarcely 

 fibrillose, but splitting with ease longitudinally, hollow, or 

 rather stuffed with fine cottony fibres, the very base solid, 

 not acrid, insipid ; smell scarcely any. The volva is easily 

 overlooked if care be not taken to dig up the very base of 

 the stem, as it is apt to be entangled in the grass. It occurs 

 of various colours ; the more general one is a mouse-grey. 

 Bolton figures a tawny variety agreeing with A. fulvus, 

 Schaefi"., t. 95. Others are figured by Schaeff"er of a bluish 

 and bay hue. Batsch has a white and Haller a green 

 variety. (Berk.) 



White. Pileus 2-3 in. broad, ovate in the volva, then 

 convex, at length plane and subumbonate, the centre sub- 

 ochraceous, at first warty then quite smooth. Flesh white, 

 very thin on the margin. Gills subdistant, broad in front, 

 narrow behind, entire. Stem 3-5 in. high, 3-4 lines thick,
