NORTH AMERICAN SPECIES OF LEPIOTA 
BY A. P. MORGAN. 
( Continued from page 203.) 
§ 2. ANNULI MOBILES. THE VEIL IN THIS SEC¬ 
TION IS MARGINAL AND INFERIOR AS IN THE FIRST 
SECTION, BUT THE DERMIS OF THE PILEUS AND 
THAT OF THE STIPE ARE DISSIMILAR, THE COL¬ 
ORED CUTICLE OF THE PI LEU 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 PILEDS. 
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 
MOBILISE 
VII. SUBCLYPEOLARIAE. Dermis of the pileus a 
thin membrane, radiately hbrillose; the cuticle at first continuous, 
at length separating into small or minute scales, which are drawn 
apart and scattered over the white hbrillose surface. The cuticle 
of the stipe commonly white, smooth and even or only appressed- 
ly hbrillose; the annulus thin and membranaceous, usually per¬ 
sistent. 
This is a large tribe of mostly small Agarics; they differ 
from the Clypeolariae in having a smooth, white stipe, free from 
the colored scales of the pileus. 
a. Scales of the pileus white, cinereous, yellowish. 
42. LEPIOTA MIAMENSIS Morgan, Myc. Flora M. 
V. 1883. 
Pileus fleshy, ovoid then convex and explanate, subumbon- 
ate; the flesh thin, white; the dermis radiately fibrillose, all white 
or a little dusky in the center, the cuticle soon separating into 
small concentric scales; the veil thin and delicate, subappendicu- 
late. Stipe slender, tapering slightly upward, fistulous, glabrous, 
all white; the annulus lacerate, subpersistent. Lamellae rather 
broad, white, free approximate; the spores oblong-ovoid, obliquely 
apiculate, 5-7 x 3 mic.
