 black - squaimilose in the centre, membranaceous, convex then 

 flattened (margin at first inflexed), striate. Stem 5-7.5 cent.

 smooth, bluish-grey-green. Gills adnate, 4 mm. (2 lin.) broad,

Allied to A. asprellus, from which it differs only in the colour, which, how- 

 ever, is constant.

465. A. asprellus Fr. Pileus 2.5-4 cent, (i-i^ in.) broad, 

 hygrophanous, at first fuliginous or mouse-colour, then livid-grey, 

 somewhat membranaceous, convex then flattened, the darker 

 umbilicus villous at length squamulose, marked with spots, striate, 

 sometimes (the disc excepted) smooth, sometimes fibrillose. 

 Stem 2.5-5 cent. (1-2 in.) long, scarcely 2 mm. (i lin.) thick, 

 cartilaginous, fistulose, thin, equal, tense and straight, even, 

 smooth, typically livid, white-villous at the base. Gills adnate, 

 separating-free, somewhat distant, plane, equally attenuated from 

 the stem towards the margin, whitish-grey, the edge, which is 

 quite entire, of the same colour. 



The stem varies fuscous, green, and azure-blue. In some larger specimens 

 the pileus is squamulose throughout. 



In open pastures and grassy places. Uncommon. 



Name asper, rough. From the roughish pileus. Fr. Monogr. i. p. 289. 

 Hym. Eur. p. 205. Berk. Out. p. 147. C. Hbk. n. 280. S. Mycol. Scot. n. 

 262. Quel. p. 89. t. 6. / 4. 



466. A. nefrens Fr. Pileus 2.5-5 cent. (1-2 in.) broad, hygro- 

 phanous, fuliginous then livid-grey, membranaceous, campanulate 

 then flattened, striate, obsoletely fibrillose, with a deep darker 

 umbilicus and at length infundibuliform. Stem 2.5 cent, (i in.) 

 long, 2 mm. (i lin.) thick, fistulose, fragile, equal, smooth, some- 

 what naked, fuscous-livid. Gills adnexed, separating, broad, 

 pallid grey, the edge slightly black but entire. 



Pileus somewhat undulated. Certainly nearest to A. serrulatus in affinity. 

 It approaches A. serrulatus as A. asprellus approaches A. chalyboeus.
