LEUCOSPORI. 



33 



more or less radiato-wrinkled, smeared over with a thick tenacious Armiilaria. 

 gluten; margin striate when thinner. Stem 4-7.5 cent - OX-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 inserted at the apex of the stem, bent downwards and ghied 

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

 swollen and entire margin which sometimes becomes fuscous. 

 Gills rounded behind, 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. Aug.-Nov. 



Very beautiful, of an exquisite pellucid white. Tough and very sticky.

Submenus IV. TRICHOLOMA (0plf, a hair, Ao^a, a fringe). Tricholoma. 

 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 on the 

 ground, fleshy, never obconic or truly 

 umbilicate. Fr. Hym. Eur. p. 47. 



The sinuate gills distinguish this 

 from all the other white-spored sub- 

 genera. None are known to be truly 

 poisonous. A few, such as A. sapo- 

 naceus, are suspicious. 



Series A. Pileus viscous, fibrillose, scaly 

 or pubescent, and not watery-moist or be- 

 coding even. F!esh no, absorbing raois ,ure 

 nor hygrophanous. Stem fibrillose, as is also 

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