AGARICUS. 



Piuteoius. at first viscous and covered over with a network of anastomos- 

 ing veins, when full grown more even or slightly pitted, slightly 

 striate at the margin. Stem 5 cent. 

 (2 in.) long, 4 mm. (2 lin.) and more 

 thick, hollow, equal, fragile (but the 

 cuticle becoming polished-even or car- 

 tilaginous), fibrillose, white, mealy at 

 the apex. Gills planely free, ventri- 

 cose, crowded, arid, dingy cinnamon. 



Spores dark ferruginous. 

 On dead wood. Rare. 



In the young state the pileus is of a delicate 

 bistre, and it is only in age that it assumes a 

 violet tinge, apparently from the colour of the 

 spores being partly seen through the flesh. 

 Care must be taken to distinguish it from

651. A. aleuriatus Fr. Pileus 1-2.5 cent - ( l A-i in.) broad, 

 bluish-grey, livid, rose-colour, somewhat membranaceous, conical 

 then convexo-plane, viscous, striate. Stem 2.5 cent, (i in.) long, 

 2 mm. (i lin.) thick, fistulose, incurved, pulverulent, white. Gills 

 free, ventricose, saffron-ochraceous. 



In structure and nature it is very closely allied to A. reticulatus, and does 

 not differ from it except in the stature of all its parts being smaller and thinner, 

 in the fistulose incurved stem being everywhere white-pulverulent, in the 'pileus 

 being somewhat membranaceous, striate but by no means wrinkled, and in the 

 gills being saffron-ochraceous and the spores bright ochraceous.

i. p. 264. Veil none or fibrillose. Stem somewhat cartil- 

 aginous, continuous with the hymenophore, tubular (tube some- 

 what hollow). Pileus more or less membranaceous, conical 

 or oval then expanded, striate, margin at the first straight, 

 addressed to the stem. Gills not decurrent. Slender, fragile.
