82 AGARICUS. 



ciitocybe becoming silky-even or squamulose ; margin involute, pubescent, 

 always even; flesh white, at length soft. Stem as much as 10 cent. 

 (4 in.) long, 2.5 cent, (i in.) thick, solid, compact, but internally 

 spongy, elastic, attenuated upwards, fibrilloso-striate, whitish. Gills 

 deeply decurrent, pointed at both ends, somewhat crowded, soft, 

 simple, whitish, not changeable. 



The pileus is always very dry because the surface absorbs moisture. Odour 

 weak, pleasant, almost that of A, infundibuliformis. On account of its gigan- 

 tic stature and colour, it has often been interchanged with A. giganteus Sow. ; 

 it is in no wise, however, allied to that species, but is so closely allied to A. 

 infundibuliformis that it might be taken for a very luxuriant form of it. 



In grassy places, banks of hedges, &c. Frequent. July-Oct.

 A. giganteus Sow. is a true Paxillus. 



162. A. infundibuliformis Schasff. Pileus about 7.5 cent. (3 

 in.) broad, flesh-colour then becoming pale tan, fleshy at the disc, 

 otherwise thin, when young moderately firm, convexo-depressed, 

 gibbous with an umbo, involute at the margin ; when fuller grown 

 softer, flaccid, wholly infundibuliform, on closer inspection silky 

 on the surface, hence bibulous, never moist ; flesh soft, white. 

 Stem 5-7.5 cent. (2-3 in.) long, 6-10 mm. (3-5 lin.) thick, spongy- 

 stuffed, externally firm, elastic, conico-attenuated, more rarely equal, 

 pallid, white-tomentose at the base. Gills very decurrent, some- 

 what crowded, very much pointed at each end, soft, shining white. 



Stem often eroded by larvae and hollow. Odour, especially when damp, 

 weak but pleasant. The pileus varies in colour, passing from rufescent into 

 tan and white, but not white at the first. 



In woods and grassy places. Common. July-Nov.

* A. membranaceus Fr. differs in all its parts being thinner, in its equal 

 stem, in the pikus being -without an umbo, and in its brighter colour. Earlier 

 than the typical A. infundibuliformis.
