DERMINI. 229 



then flattened, obtuse, "viscous; flesh compact, white. Stem solid, Phoiiota. 

 when young very compact, hard, and somewhat bulbous, then 

 elongated, somewhat equal, fibrillose (not scaly), white. Ring 

 more or less in the form of a cortina, floccose, moderately persist- 

 ent. Gills adnato-decurrent, not much crowded, quite entire, 

 white then becoming fuscoiis-clay-colour. 



Stem, which occurs at length also hollow, more or less curved from situation. 

 Inodorous. Scarcely caespitose though often a few individuals are joined at 

 the base. It is readily distinguished from all its allies by the paler superficial 

 scales on the pileus, and from neighbouring species by the fuscous ferruginous 

 colour of the spores. 



On trunks of beech. Rare.

505. A. heteroclitus Fr. Pileus 5-7.5 cent. (2-3 in.) then 10- 

 12.5 cent. (4-5 in.) broad, whitish or yellow, tawny when old, 

 fleshy, compact and when young hard, most frequently excentric, 

 hemispherical then flattened, very obtuse, sometimes even ; com- 

 monly broken up into broad, scattered, innate, adpressed, spot-like 

 (darker) scales, sometimes viscid when old and wet ; flesh thick, 

 firm, pallid. Stem curt, about 5 cent. (2 in.), thickened-bulbous 

 and bluntly-rooting at the base, 1-2.5 cent. (%-i in.) thick, solid, 

 hard, stout, fibrillose, white, commonly curved-ascending, veiled 

 at the apex, internally rhubarb - coloured at the base. Gills 

 rounded behind, slightly adnexed, very broad, plane, crowded, at 

 first pallid, at length dirty ferruginous. 



Disc piano-truncate. The veil is more rarely in the form of a perfect ring 

 at the very apex of the stem, commonly appendiculate on the pileus or in the 

 form of a cortina, floccoso-radiate, but always encircling the stem with an 

 annular zone. Solitary. Most distinct from its strong pungent odour, almost 

 that of horse-radish. 



On trunks of poplar and birch. Bromley, &c.

 broad, yellow or ferruginous - yellow, fleshy, campanulate then 

 convex, compact at the disc and hence gibbous when expanded, 

 moist, scarcely viscous, with darker adpressed spot-like scales, 

 when young sprinkled with floccose scales towards the margin ; 

 flesh both of pileus and stem white, at length becoming yellow. 

 Stem about 7.5 cent. (3 in.) long, 12 mm. (^ in.) and more thick,
