AGARICUS. 



Ecciiia. 480. A. Parkensis Fr. — Pileus scarcely 2.5 cent, (i in.) broad, 



fuscous when moist, blackish when dry, by no 7neans hygro^han- 



otis, membranaceous, piano - convex, 

 deeply iiinbilicate, very smooth (by no 

 means fibrillose), slightly striate to the 

 middle. Stem short, scarcely 2.5 cent, 

 (l in.) long, not 2 mm. (i lin.) thick, fis- 

 tulose, attenuated downwards, smooth, 

 not dotted, fuscous. Gills decurrent, 

 crowded, distinct, linear and almost 2 

 mm. (i lin.) broad, whitish then be- 

 coming dingy flesh-colour. 



A very remarkable species, of which it is 

 difficult to indicate the nearest affinity. Easily 

 distinguished from neighbouring species by 

 the pileus not becoming pale with dryness.

 little more broad, hygropha7tous, umber or fuscous when moist, 

 grey when dry, membranaceous, deeply umbilicate, at first convex

 2 mm. (i lin.) thick, fistulose, equal, smootJi, somewhat naked, of
