* Pileus cinereous or fuscous. 



132. A. nebularis Batsch. Pileus 7.5-12.5 cent. (3-5 in.) broad, 

 fuliginous or fuscous, at length grey, fleshy, somewhat compact, 

 convex then becoming plane, very obtuse, at length depressed at 

 the disc, dry; at the first (in dry weather) covered over with a 

 grey, pruinose cloudiness, but when full grown and in wet weather 

 quite naked, smooth (more rarely innately streaked or shining 

 when scorched by the sun) ; flesh compact, white. Stem 7.5 cent. 

 (3 in.) long, about 2.5 cent, (i in.) thick, stout, remarkablyy^/y, 

 at first solid, but soft within and at length occasionally hollow, 

 spongy-elastic, attenuated upwards (obclavate), fibrillose-striate, 

 white. Gills shortly and equally decurrent, arcuate, very crowded, 

 thin, pallid white, sometimes becoming yellow. 



Robust, laxly gregarious, slightly odorous. The pileus may be even white 

 like the flesh. The stem varies, curt, equal, also villous and squamulose. It 

 may be easily interchanged with a form of A, humilis with spuriously de- 

 current gills which is thinner and more fragile. 



In woods, &c. Common. Aug.-Nov. 



Spores 3x4 mk. W.G.S. ; 3-5x3 mk. B. Margin of pileus at first invol- 

 ute, sometimes quite regular, sometimes waved. It smells of curd cheese.

133. A. clavipes Pers. Pileus 4-5 cent. (1^-2 in.) and more 

 broad, sometimes of one colour, fuscous, fuliginous, cinereous- 

 livid, sometimes whitish round the margin, very rarely wholly 

 white, fleshy, slightly convex, soon plane, at length almost obconi- 

 cal, very obtuse, even, smooth, dry ; flesh lax, white, thin towards 

 the margin. Stem 5 cent. (2 in.) long, conical, 12 mm. (}4 in.) 

 and more thick at the base, solid, internally spongy, somewhat 



Jibrillose, fuliginous-livid. Gills deeply decurrent, descending in a 

 straight line, somewhat distant, flaccid, quite entire, broad, wholly 

 and persistently white, but varying yellow. 



Of the same colour as A. nebularis, but most distinct in its nature. 

 Odour mild, pleasant. Substance wholly soft, elastic.
