33 



more or less radiato-wriJikled, smeared over with a thick tenacious Armillaria. 

 gluten; margin striate when thinner. Stem 4-7.5 cent. (iX~3 in.) 

 long, 2-4 mm. (1-2 lin.) thick at the apex, thickened at the base, 8 

 mm. (4 lin.), stuffed, thin, rigid, curved-ascending, smooth, white, 

 but fuliginous-scaly at the base when most perfectly developed. 

 Ring i7iserted at the apex of the stem, bent downwards and glued 

 close to the stein, silicate; the white border again erect, with a 

 swollefi a7id entire margi?i which sometimes becomes fuscous. 

 Gills rounded behijtd, obtuse, adhering to the stem and striato- 

 decurrent, distant, broad, lax, mucid, always shining white. 



Very variable in stature, from 2.5 cent, (i in.) (when of this size the stem is 

 almost equal) to as much as 15 cent. (6 in. ) broad. The colour of the pileus 

 varies grey, fuliginous, olivaceous. The gills sometimes become yellow, but 

 only from disease. Sometimes solitary, sometimes a few are joined in a caes- 

 pitose manner at the base. 



On beech. Frequent.

 Fr. Syst. Myc. i. p. 36. Veil obsolete or only consisting of flocci 

 or fibrils which adhere to the margin 

 of the pileus. Stem fleshy, not fur- 

 nished with a bark. Hymenophore 

 continuous with the stem, gills sin- 

 uate behind. All growing 07t the 

 ground, fleshy, 7iever obconic or truly 

 timbilicate. Fr. Hym. Etir. p. 47. 



The si7tuate gills distinguish this 

 from all the other white-spored sub- 

 genera. None are known to be truly 

 poisonous. A few, such as A. sapo- 

 7iace7is, are suspicious. 



Series A. — Pileus viscous, fibrillose, scaly 

 or pubescent, and not watery-moist or be- 

 coming even. Flesh not absorbing moisture 

 nor hygrophanous. Stem fibrillose, as is also 

 the universal veil, which is adnate (and scarcely distinctly conspicuous)
