340 FUNGUS-FLOEA. 



has observed tlie gills to ^lonr forth a sulphur- coloured milk, 

 like A. scrohiculatus. (Berk.) 



Readily distinguished from allied species by the following 

 characters : — stem hollow, straight, cylindrical, fibrosely 

 striate ; pileus siibmembranaceous, acutely conical, glabrous, 

 more or less-lobed, then exi)anded and cracked, not becoming 

 pale when dry, as in allied species, but shining in dry weather, 

 and becoming blackish m rainy w^eather ; gills narrowed 

 behind and almost free ; ventricose, thin, rather crowded, 

 but varies to yellow, whitish, smoky, and in purple -crimson 

 forms, reddish at the base. (Fries.) 



A polymorphous plant, especially in regard to colour. 

 Pileus acutely conical, smooth, shining, particular when 

 young, fleshy, margin striate, irregular, frequently lobed, 1-2 

 in. from the base to the apex of the cone, becoming partly ex- 

 panded in age, the margin sometimes turning up, and even 

 revolute, mostly some shade of deep yellow, orange, or bright 

 red, often intermixed with each other, in some varieties 

 brown or even black, the brightest colour then remaining 

 longest at the margin ; lamella numerous, more or less deep 

 yellow, ventricose, but attenuated towards the stipes, to 

 which they are frequently slightly attached. Stipes hollow, 

 with a great tendency to split, variously coloured, like the 

 pileus, 2-3 in. high, diameter various. (Grev.). 



Hygrophorus (Hygro.) calyptraeformis. Berk. 



Pileus lh-2h in. high and the same across when expanded, 

 flesh very thin, at first acutely conical, then splitting and 

 expanded, the margin eventually much upturned, innately 

 fibrillose, pale clear rose-colour, becoming paler with age ; 

 gills narrowed behind and slightly adnexed 1-1 J line broad, 

 rather distant, pale rose-colour then whitish ; stem 3-4 in. 

 long, l-h in. thick, slightly striate, white, fragile hollow ; 

 spores elliptical, 7x4^.

Among grass. 



Habit of H. conicus, but very distinct in colour and in not 

 turning black. A very beautiful species. Fragile.
