NEW YORK SPECIES OF LEPIOTA. 
‘‘White-spored, hymenophorum distinct from the stem, veil uni- 
versal, concrete with the epidermis of the pileus. Lamellee free, often 
remote, neither sinuate nor decurrent.” — Hymen. Hurop., p. 29. 
The word Lepiota has reference to the scaly character of the pileus. 
The species grouped under this name may be distinguished from the 
species of Amanita by the character of the scales of the pileus, which 
in that subgenus are wart-like and superficial and for the most part 
easily separable from the pileus, while in this they are intimately 
united to the cuticle, which usually breaks up into scales or scale-like 
fragments. On the other hand they are distinguished from the species 
of Armillaria by the lamellee which in most of the species do not reach 
the stem but are wholly free from it. In the few instances in which 
they reach the stem.they are but slightly attached to it, and not sin- 
uate or decurrent as in Armillaria. 
The species are mostly of medium size, though Agaricus procerus 
has few rivals in length of stem, and A. Morgani in breadth of pileus. 
The pileus is soft and fleshy but generally rather thin. The cuticle, 
which is usually entire in the very young plant, soon breaks up into 
scales which are appressed or erect, large or small, fibrillose, floccose, 
granular or mealy according to the species. These scales often give 
an ornamental or variegated appearance to the pileus which is quite 
attractive. In form, the pileus in the young plant is subglobose or 
ovate, then it becomes convex or campanulate and finally in many 
species it is nearly flat with a central prominence or umbo. This 
umbo in such species as A. procerus and A. mastoideus is especially 
prominent. 
The lamelle are white or whitish in most of the species. Occa- 
sionally they may be tinged with yellow and in a few species they 
assume a smoky-red or pinkish-brown hue in old age or in drying. In 
A. Badhami, A. meleagris and A. Americanus the whole plant changes 
color when wounded or in drying. 
The stem in most of the species is rather slender and either hollow 
or stuffed with webby or cottony filaments. The annulus or ring that 
is attached to and surrounds the stem is sometimes slight and disap- 
pears in very wet weather or in old age. The spores, which are nor- 
mally white, sometimes assume a yellowish hue when kept a long time. 
A. Morgani, an Ohio species, is remarkable for producing spores of a 
bright-green color which soon fades to a dull-green. The spores vary
