220* AGARICUS. 



Phoiiota. convexo-plane, obtuse, smooth, then cracked into patches, margin 

 even. Stem commonly curt, 5 cent. (2 in.) long, about 12 mm. 

 (Yz in.) thick, stuffed, even solid, hard, becoming silky-even, then 

 longitudinally cracked when dry, thickened at the apex, mealy 

 and more than usually widened into the pileus, varying ventri- 

 cose and irregularly shaped. Ring torn. Gills adnate, striato- 

 decurrent with a tooth, ventricose, 12 mm. (y z in.) broad, livid 

 th en fuscous-ferruginous. 



The stem is abundantly furnished with fibrillose rootlets at the base. 

 Although very closely allied to A. prcecox, it is readily distinguished by its 

 ferruginous or brown-ferruginous spores. 



In garden ground. Uncommon. Spring and Autumn.

497. A. prsecox Pers. Pileus about 7.5 cent. (3 in.) broad, 

 whitish then tan colour, fleshy, soft, convex, soon plane, obtuse, 

 even, smooth, moist but not viscous in rainy weather, becoming 

 pale; flesh soft, white. Stem 7.5-10 cent. (3-4 in.) long, 6-8

Spores brown inclining to fuscous. There is,a var. much smaller by waysides : 

 pileus 2.5-4 cent - U- 1 ^ in -) broad; stem 2.5-4 cent, (i-i^ in.) long, 2-4 

 mm. (1-2 lin.) thick, stuffed with a soft pith ; ring fugacious or only appen- 

 diculate. 



In pastures, waysides, &c. Common. Spring-Autumn. 



Ring striate above. Paler than A. durus, but it is very doubtful whether it 

 is really distinct. M.J.B. Spores sphasroid- ellipsoid, 8-13x5-7 mk. K. ;
