ORED CUTICLE OF THE PI LEI'S NOT BEING CONTIN- 

 UED DOWNWARD UPON THE STIPE, RARELY COLOR- 

 ING EVEN THE UPPER MARGIN OF THE VEIL. THE 

 VEIL IS ANNULATE UPON THE STIPE AND IS COM- 

 MONLY A THIN MEMBRANACEOUS BAND, THOUGH 

 SOMETIMES IT IS THICKENED AND SUBCORIACE- 

 OUS; IT IS CONTINUOUS DOWNWARD WITH THE 

 DERMIS OF THE STIPE, AND BY ITS UPPER BORDER 

 CONNECTS WITH THE DERMIS OF THE PILEUS. 

 SOMETIMES THE VEIL IS FIRST TORN AWAY FROM 

 THE STIPE AND DRAWN UPWARD TO SOME EXTENT 

 UNTIL THE EXPANSION OF THE PILEUS BEGINS, 

 THUS GIVING RISE TO THE TYPICAL "ANNULUS 

 MOBILIS/' 



VII. SUBCLYPEOLARIAE. Dermis of the pileus a 

 thin membrane, radiately hhrillose ; the cuticle at first continuous, 

 at length separating into small or minute scales, which are drawn 

 apart and scattered over the white Hhrillose surface. The cuticle 

 of the stipe commonly zvhite, smooth and even or only appressed- 

 ly hhrillose ; the annulus thin and membranaceous, usually per- 

 sistent. 



a. Scales of the pileus zvhite, cineleous, yellowish. . . 



Species : 42-45 



b. Scales of the pileus red, rufous, fulvous. 



Species: 46-52 



c. Scales of the pileus brown or blackish. . Species : 53-59 



VIII. HIATULOIDES. Pileus submembranaceous, thin, 

 soft and flexible, umbonate ; the flesh ivcll nigh obsolete except 

 beneath the central disc; the dermis radiately hbriUose and pli- 

 cate-sulcate often to the umbo; the cuticle separating into scales. 

 Stipe slender and sometimes much elongated, hsttdous and fragile, 

 sub glabrous; the annulus thin and membranaceous. 



a. Pileus zvhite with pallid or browmish scales. 



Species : 60-66 



b. Pileus white with yellozv or all yellow. . Species 67-72 



IX. PROCERAE. Pileus thick and fleshy, usually um- 

 bonate ; the dermis floccosc or Hbrillose beneath the cuticle ; the 

 cuticle at first smooth and continuous, at length commonly sep- 

 arating into large irregular scales zvhich are more or less de- 

 ciduous. Stipe tapering upzvard from a thickened or bidbous 

 base; the annulus often thick subcoriaceous, and truly movable. 



a. Lepiotae of the largest size: the anmdus thick and easily 



movable Species : 73-77 



b. Lepiotae of small size; the annulus thin membranaceous, 



and not easily movable. . . Species : 78-83
