PRATELLI. 311 



(2 in.) broad, pallid light yellow, but becoming livid-purple with Stropharia 

 the dense gluten with which it is at first besmeared, fleshy, con- 

 vexo - plane, somewhat umbonate, pelliculose, viscid, smooth, 

 slightly striate at the margin ; flesh thin, soft, white. Stem 7.5 

 cent. (3 in.) \ong,Jistulose, thin, equal, very flexuous, often decum- 

 bent, very soft, dry, shining white, < =\\k\-fibrillose below the medial 

 distant fugacious ring. Gills adnate, with a decttrrent tooth, 6 

 mm. (3 lin.) broad, scarcely crowded, whitish then becoming 

 fuscous, when bruised whitish at the sides. 



Spores fuscous-purple. Gregarious, somewhat caespitose. There are two 

 forms : one with the pileus campanulato-expanded, and the stem stuffed ; 

 another with the pileus convexo-plane, more evidently umbonate, and the 

 stem hollow. Very remarkable, soft, the pellicle of the pileus easily separat- 

 ing. 



In pastures. Ely, &c. Oct.-Nov. 



Stem 6 cent. (2% in.) high, 6 mm. (3 lin.) thick, stuffed, composed of fibres. 

 Resembling some states of A. ceruginosus, but the spores are of a different 

 colour and much smaller. B. & Br. Spores 7 mk. B. dr 5 Br. ,'9x5 mk.

697. A. obturatus Fr. Pileus light yellow, fleshy, for the most 

 part thick, convex then plane, obtuse, obsoletely viscid, commonly 

 dry, even but often rimosely squamulosej flesh compact, shining 

 white. Stem short, 2.5-4 cent, (i-i^ in.) long, 6 mm. (3 lin.) 

 and more thick, firm, stuffed, attenuated downwards, even, not 

 scaly, white. Ring superior, deflexed, white. Gills adnate and 

 without a decurrent tooth, crowded, plane, white then becoming 

 Purple- umber. 



Readily distinguished from preceding species by its obese stature and 

 compact Jlesh. The spores are fuscous on a white ground, vinous-purplish on 

 a black ground. The gills never become ferruginous ; they often become 

 sterile and remain white, so that it may be easily taken for a species of 

 A r mill aria. 



On the ground among grass. Rare.

 tened, obtuse, pelliculose, viscid in wet weather, shining when 

 dry, even, smooth, never rimosely squamulose ; flesh soft, white.
