PRATELLI. 311 



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

 the dense gluten with which it is at first besmeared, i^eshy, con- 

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

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

 cent. (3 in.) \QX\<g,Jistiilose, thin, equal, very flexuous, often decum- 

 bent, very soft, diy, shini?2g white, s\W\-fibrillose below the medial 

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

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

 fuscous, when bruised whitish at the sides. 



Spores fuscous-purple. Gregarious, somewhat caespitose. Ihere 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.

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

 Resembling some states of A. cB7-ugiTiosns, but the spores are of a different 

 colour and much smaller. B. cr= Br. Spores 7 mk. B. 6= Br. ,-9x5 mk.

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

 part thick, convex then plane, obtuse, obsoletely viscid, co?nmonly 

 dry, even but often rimosely squajnulosej flesh compact, shining 

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

 and more thick, firm, stuff'cd, attenuated downwards, even, not 

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

 without a decurrent tooth, crowded, plane, white then beco^ning 

 purple-umber. 



Readily distinguished from preceding species by its obese stature and 

 compact 'flesh. 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 miliaria. 



On the ground among grass. Rare. 



Spores 6x9 mk. W.G.S.; 7x4 mk. W.P. Name — obturo, to stop up, 

 close. Perhaps from the stuffed stem. Fr. Monogr. i. p. 412. Hym. Flur.

698. A. melaspermus Bull.— Pileus 2.5-5 cent. (1-2 in.) broad, 

 yellow, changing colour when old, fleshy, soft, convex then flat- 

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

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