76 AGARICUS. 



Ciitocybe. even, smooth, but at the first floccoso-fibrillose, the involute margin 

 villous; flesh soft, white. Stem 5-7.5 cent. (2-3 in.) long, solid, 

 fleshy-fibrous, elastic, thickened and more or less white-tomentose 

 at the base, naked upwards, even. Gills adnate, then slightly 

 decurrent, very crowded, thin, quite entire, narrow, never becom- 

 ing yellow. 



Inodorous, taste mild. Often growing in troops. It differs from A. (Trich.) 

 albus in the gills never becoming yellow. Compare Bull. t. 118, different 

 from Hygrophorus eburneus in the crowded, very thin gills, and smooth stem. 



In mixed or fir woods. Frequent. April-Oct. 



Not umbonate as A. opacus. M.J.B. Spores 3 mk. W.G.S. Probably 

 edible. Name cerussa, white-lead. Fr. Monogr. i. p. 108. Hym. Eur. p.

* A. difformis Schum. Caespitose, often gigantic ; pileus 

 undulato-lobed ; stem curt, sulcate or longitudinally wrinkled ; 

 gills at length pallid. 



It varies with the pileus at first sprinkled with flocci, 5-17.5 cent. (2-7 in.) 

 broad in the same cluster, the stem of the larger specimens 2.5 cent, (i in.) 

 thick and long. On rich ground. Spores 4x3 mk. B. Schum. p. 335. Fr.

148. A. phyllophilus Fr. Pileus 5-10 cent. (2-4 in.) broad, 

 tan then becoming pale white (of the same colour when moist and 

 dry), fleshy, convex then piano-depressed, obtuse, but never truly 

 infundibuliform, often excentric and repand, without stria?, 

 sprinkled with very thin silky superficial villous down, and silky 

 towards the margin. Stem about 5-7.5 cent. (2-3 in.) long, 

 elastic, externally fibrous, internally stuffed \vith a spongy pith 

 and hollow when this disappears, always tough, incurved (but not 

 bulbous) and villous at the base, white. Gills adnate, slightly 

 decurrent, 4-6 mm. (2-3 lin.) broad, scarcely crowded, at first 

 white, then becoming pale, almost tan-white. 



Tough, by no means hygrophanous, odour scarcely remarkable. The stature 

 like that of A. pithyop'hilus, &c., varies exceedingly, sometimes small and 

 solitary, sometimes large and casspitose. Stem sometimes straight, sometimes 

 decumbent, sometimes smooth upwards. 



In woods among leaves, chiefly beech. Common. Sept.-Oct. 



Distinguished from A. cerussa tits by its umbilicate pileus, and the gills 

 changing at length to yellow. M.J.B. Spores 6x3 mk. W. G.S. ; 4-8x3-5.
