squamulose except the umbo, often radiately rimose, whitish, with 
brownish squamules and blackish brown or fuscous umbo, flesh 
white, unchangeable, taste sweet, agreeable; lamellae thin, close, 
free, white becoming brown or blackish brown; stem equal or 
tapering upward, stuffed or hollow, whitish, sometimes brownish 
below the white annulus; spores .0002-.00024 of an inch long, 
.OOOT4—.00016 broad. 
Pileus 1-2 inches broad; stem 1-1.5 inches long, 2-3 lines

Near Trenton, N. J. September. E. B. Sterling. 
Growing with Agaricus placomyces Pk. from which 
it differs in its smaller size, campanulate pileus and brown umbo. 
It is one of the few species in which the color of the lamellae 
changes from white to brown without any intervening pink color. 
From similar species of Lepiota it may be distinguished by its 
brown spores and brown mature lamellae.
