Hygrocybe. **** Stem inclining to fuscous ; cortina of a pallid dirty colour or white 

 (not yellow) ; gills dark. 



II. Tenuiores. Pileus somewhat membranaceous, conical then expanded, 

 umbonate, umbo acute or more rarely obtuse and vanishing (the opposite is 

 the way of the Firmiores), margin at first straight. Stem somewhat equal or 

 attenuated at the base. {The thinness of the pileus is only relative to its size.) 



* Stem white. 



** Stem inclining to violet or reddish. 



*** Stem yellowish, commonly becoming pale.

106. C. subferrugineus Fr.— Pileus about 7.5 cent. (3 in.) 

 broad, ferruginous or watery cinnamon, more or less hygrophan- 

 ous, when dry sometimes shining and tawny, sometimes becom- 

 ing pale, unequally fleshy, abruptly more compact at the disc, 

 convex then expanded, obtuse, here and there flexuous, firm but 

 not rigid, even, smooth ; flesh scissile, dingy, isabelline-white. 

 Stem variable in stature, commonly 7.5 cent. (3 in.) long, 12 mm. 

 {% in.) thick, solid, more or less bulbous, attenuated upwards, 

 adpressedly fibrillose, externally rigid and somewhat cartilagin- 

 ous, pallid, internally soft, saffron - yellow at the base. Veil 

 entirely fibrillose and marginal only, not sheathing, very fuga- 

 cious. Gills remarkably emarginate, 6 mm. (3 lin.) broad, ?nore 

 or less crowded, opaque, at first pallid, soon watery then dark 

 ferruginous. 



Among heaped rotting pine-leaves the stem is stout, very inflated, spongy. 

 Odour that of the Inolomata, taste unpleasant. There are many forms definite 

 as to colour, but scarcely to be defined by description. It differs from C. ar- 

 meniacus in the opaque colour, in the fleshy obtuse pileus, in the stem not 

 being elastic, in the veil not collapsing, &c, and from C. bivelus in the simple 

 veil, the smooth and hygrophanous pileus (watery ferruginous when moist, 

 becoming tan-ferruginous when dry), &c.

 tusely umbonate, even, smooth, not viscid, here and there slightly 

 striate at the margin; flesh somewhat of the same colour, scissile.
