Pileus subcampanulate becoming convex, striatulate, brown, 

 sometimes with a pinkish tinge ; lamellae numerous, uncinate,

This species is distinguished from A. galericulatus by the 

 lamellae being united with each other at the stipe as if in a 

 collar, and in not being venose-connected.

Pileus convex, becoming expanded, umbonate, striatulate, 

 grayish-brown ; lamellae not uncinate, rather broad, subventri- 

 cose, nearly free, sordid white ; stipe slender, smooth, hollow, 

 equal or slightly narrowed upward, villous at the base, pallid.

 June. 



I have found this plant in but one locality. It is quite 

 distinct from all other Mycencd known to me, by its broadly 

 convex or expanded umbonate pileus. The umbo is small 

 and subacute. The pileus becomes of a whitish-gra}' color 

 in drying, and appears to be covered with numerous whitish 

 fibrils. The lamellae reach the stem, but are slightly attached 

 to it and easily separated from it. (Plate 5, figs. 6-11.) 



44. Agaeicus pueus Fers. 



Pileus convex, smooth, striatulate, pinkish-purple or lilac ; 

 lamellae rather broad, sometimes rounded, sometimes sinuated 

 at tiie inner extremity, connected by numerous veins, colored 

 like the pileus ; stipe firm, smooth, hollow, concolorous ; plant 

 odorous. 



Height about 2', breadth of pihnis 6"- 12". 



Pine woods. West Albany and Sandlake. October.
