2l6 AGARICUS. 



Noianea. In grassy places. Holm Lacy, 1879. 



Plowright has indicated the opinion {Gard. Chron. Oct. 14, 1882) that A. 

 piceiis and A. nigripes may be one, and that possibly both may be identical 

 with A. cucumis and A. pisciodorus. Name — pix, pitch. Pitch-black.

476. A. infula Fr. — Pileus 1-4 cent, [yi-iyi in.) broad, fawn 

 or fuliginous when damp, isabelline-livid when dry, shining in 

 either state, membranaceous, pliant, conical or campanulate, often 

 repand and irregularly formed when larger, centre at length 

 depressed, smooth, even. Stem 2.5-7.5 cent. (1-3 in.) long, some- 

 what fistulose, cartilaginous, very tough, striate, polished and 

 quite naked, even, smooth, of the same colour as the pileus, pubes- 

 cent with the mycelium at the base. Gills typically adnexed 

 and separating-free, thin, jmr?'ow, very much crowded, at the first 

 s]ii?ti7ig white, then bright rose-colour. 



In stature and size it varies much like its allies, but differs remarkably from 

 all of them in its extraordinary toughness, its polished appearance, and in the 

 earliest colour of the gills being of a dazzling whiteness. Sometimes it is very 

 small, with the filiform stem 2.5 cent, (i in.) long, sometimes larger and 

 firmer (but always comparatively slender) 7.5 cent. (3 in.) It varies in the 

 insertion of the gills. Var. versiformis : smaller; pileus 12 mm. {% in.) 

 broad, umbonate, convex then depressed, then papillate in the centre, slightly 

 but very densely striate, silky-shining when dry, sometimes infundibuliform , 

 the papilla, however, persistent. On burnt ground.

**** Gills whitish. Pileus not hygrophanous. 



477. A. verecundus Fr. — Pileus watery reddish, but very 

 pallid, not changing colour when dry, somewhat membranaceous, 

 slightly fleshy at the disc, at tirst somewhat umbonate, then rather 

 obtuse (never depressed), obsoletely pellucid-striate to the middle 

 when damp, but wholly even at the disc, at first sight smooth, but 

 when more closely examined obsoletely silky towards the fioccu- 

 lose margin. Stem 4-5 cent. (iX~2 in.) long, 2-4 mm. (1-2 lin.) 

 thick, slightly firm, somewhat fistulose, cartilaginous, but not 

 very rigid and when crushed splitting into fibrils, becovmig pale, 

 mealy at the apex. Gills adnate, separating, rather thick, dista7it, 

 distinct, ventricose, in the form of a segment, 4 mm. (2 lin.) and 

 more broad, ascending-plane, whitish, watery. 



Spores reddish. Densely gregarious or growing in troops. Scarcely allied 

 to any.
