101. AGARICUS SOLIDIPES 7”. Sp. 
Pileus firm, at first hemispherical, then subcampanulate or 
convex, smooth, whitish, the cuticle at length breaking up 
into dingy-yellowish, rather large, angular scales; lamelle 
broad, slightly attached, whitish, becoming black ; stipe firm, 
smooth, white, solid, slightly striate at the top; spores very 
black with a bluish tint. Ce Re a 
Height~5’-8'’, breadth of pileus 2-3’, stipe 2’-4” thick. 
Dung heaps. West Albany. June. 
A large species, remarkable for its solid stem. The scales 
on the pileus are larger on the disk, becoming smaller toward 
the margin. The upper part of the stipe is sometimes beaded 
with drops of moisture. (Plate 4, figs. 1-0.) 
102. AGARICUS FIMICOLA F7. 
Pileus subcampanulate or convex, smooth, moist, pale 
erayish-brown tinted with ochre, girt with a narrow darker 
marginal band; lamellae broad, attached, becoming blackish 
with a grayish-purple tinge; stipe hollow, pallid, pruinose 
above.

Dung heaps. West Albany. June. 
The plant is sometimes ceespitose. The pileus is often darker 
on the disk and sometimes spotted or scaly there. The mar- 
ginal zone is more distinct in young and moist specimens, 
becoming obsolete or even disappearing in old or dry ones.

broadly subumbonate, reticulate-veined, grayish-white, the
