 slightly emarginate, brownish-lilac ; stem equal, smooth, stuffed, reddish-brown ; 

 spores subelliptical, minute, .00012' long.

 veinlets which descend on the lamellae ; stem short, slender, firm, smooth or 

 sprinkled with minute mealy particles. 



Plant gregarious, white throughout, 8"-12" high, pileus 2"-4 // broad.
