collar, and in not being venose-connected.

une. 
I have found this plant in but one locality. It is quite 
distinct from all other MZycene known to me, by its broadly 
convex or expanded umbonate pileus. The umbo is small 
and subacute. The pileus becomes of a whitish-gray color 
in drying, and appears to be covered with numerous whitish 
fibrils. The lamellee reach the stem, but are slightly attached 
to it and easily separated from it. (Plate 5, figs. 6-11.) 
44. AGARICUS PURUS Pers. 
Pileus convex, smooth, striatulate, pinkish-purple or lilac ; 
lamellee rather broad, sometimes rounded, sometimes sinuated 
at the inner extremity, connected by numerous veins, colored 
like the pileus ; stipe firm, smooth, hollow, concolorous ; plant 
odorous. 
Height about 2’, breadth of pileus 6’-12”. 
Pine woods. West Albany and Sandlake. October.
