HYGROPHORUS. 89 



yellow, becoming tawny at the base. Gills adnexed, ventricose, Hygro- 

 but at length separating, free, veiy broad (12 mm., y z in.), thick, p 

 distant, almost white. 



The stem is hollow and hence flattened, but the walls are slightly firm and 

 somewhat cartilaginous, fragile however and easily splitting into crisped 

 fibres. The gills are much more rigid and firm than in allied species. A. 

 laceratus Bolt. t. 68 which is referred to this species by Secretan is rather a 

 luxuriant form of H. conicus. 



In woods. Mossburnford. Oct. 



Name obrussa, the testing of gold. From the pure golden colour. Fr.

48. H. conicus Fr. Pileus commonly light yellow, becoming 

 black, somewhat membranaceous, conical, acute, smooth, often 

 lobed, then expanded and cracked. Stem hollow, cylindrical, 

 tense and < ~>\.\'&\v^\\.,fibroso-striate. Gills attenuato-free, ventricose, 

 thin, somewhat crowded, varying white, light yellow, &c. 



Very easily distinguished from all neighbouring species by its juicy and 

 fragile substance, &c. Viscid when moist, shining when dry. It is smooth 

 even when dry. The primary colour depends upon the weather. It has the 

 singular character of the flesh becoming black when broken, but in some forms 

 (springing in dry weather) it is unchangeable. The following forms may 

 be noted : a) coccinea, scarlet and shining, gills yellow, often reddish at the 

 base : b) lutea, pileus and gills yellow neither becoming black : c) pileus 

 reddish or tawny, gills yellow : d) sulphured, pileus bright light yellow-sulphur- 

 colour, sometimes greenish, gills often whitish both becoming black when 

 broken : e) squalida, pileus livid or fuliginous-light yellow : f ) tristis, pileus 

 at the first fuliginous, soon shining black both of their own accord becoming 

 wholly black. 



In pastures. Very common. July-Nov. 



Pileus 2.5-6 cent. (1-2% in.) Stem varying very much in length and 

 thickness. Spores sphasroid-ellipsoid, 10-11 x 6-8 mk. K. ; n x 6 mk. W. G.S. 

 Name from its conical shape. Fr. Monogr. ii. p. 142. Hym. Eur. p. 419.

49. H. calyptraeformis B. Br. Pileus about 2.5 cent, (i 

 in.) high, 18 mm. (^ in.) broad at the base, pink, becoming pallid, 

 thin, acutely conical, lobed below, moist when unexpanded, striate 

 under a lens, minutely innato-Jibrillose. Stem 2.5 cent, (i in.) or 

 more long, hollow, the walls fibrous within, remarkably smooth, 

 slightly striate, brittle, often splitting longitudinally, white. Gills 

 acutely attenuated behind, very narrow, distinct, rose-coloured at 

 length pallid. 



The gills are often almost evanescent behind. The stem is pure white, 

 except within the pileus where it has often a roseate tinge. Very distinct from 

 H. conicus. It does not turn black when bruised.
