166 OUTLINES or BRITISH FUNGOLOGY. 



A. PRATENsis^ Vitt. ; distinguislicd by the small rufous 

 scales of the pileus, and the flesh having a slight pink 

 tinge. King's Cliffe. East Bcrgholt. 



A. viLLATicuSj BroncL, acquires a large size, and is very 

 scaly. 



This has been found by Dr. Badham in Suffolk. 



A. siLvicoLA, Vilt., has a shining, smooth pileus, and an 

 elongated bulbous stem, and is not uncommon in woods. 



The jNIushroom of our gardens is also a distinct form, re- 

 markable for its brownish hue and fibrillose or squamulose 

 pileus. Mr. Buchanan has sent a very distinct bed-Mushroom, 

 Avhich has the merit of being excellent in quality, and ex- 

 tremely prolific. It has a Avhite, opaque, nearly smooth, 

 depressed pileus. He also sent at the same time a variety 

 with a tall stem and somewhat bulbous base, approaching A. 

 silvicola, Vitt. 



A. VAPORARius, otto, has a broad, entire ring, while A. 

 iHiporarius, Vitt., has a brown pilose coat, which covers the 

 stem as well as the pileus, and leaves transverse fragments on 

 the stem as it elongates. Finally, a very distinct variety is 

 represented in our Plate 10, fig. 3, which is rufous, like A. 

 vaccinus, and whose flesh turns of a bright red when bruised. 

 In this the gills are at first perfectly white, as in A. cretaceus. 

 All of these might be proposed as distinct species, with al- 

 most as much justice as the two or three which follow. 



312. A. (Psalliota) arvensis, Schaff. ; pileus fleshy, ob- 

 tusely conico-carapanulate, then expanded, at first floccose, 

 then smooth, even, or rivulose ; stem hollow, with a floccose 

 pith ; ring broad, pendulous, double, the outer split in rays ; 

 gills free, wider in front, at first dirty-Avhite, then browu, 

 tinged with pink. (Plate 10, fig. 4.)—Huss. i. t. 76, 77. 



In meadows, forming large rings, and attaining an enor-
